Answer:

A. 6m and 2m

E. 11.25m and 3.75m

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

Verify each case

case A) 6m and 2m

[tex]\frac{6}{4.5}=\frac{2}{1.5} \\ \\6(1.5)=2(4.5)\\ \\9=9[/tex]

therefore

The legs are proportional

case B) 8m and 5m

[tex]\frac{8}{4.5}=\frac{5}{1.5} \\ \\8(1.5)=5(4.5)\\ \\12\neq22.5[/tex]

therefore

The legs are not proportional

case C) 7m and 3.5m

[tex]\frac{7}{4.5}=\frac{3.5}{1.5} \\ \\7(1.5)=3.5(4.5)\\ \\10.5\neq15.75[/tex]

therefore

The legs are not proportional

case D) 10m and 2.5m

[tex]\frac{10}{4.5}=\frac{2.5}{1.5} \\ \\10(1.5)=2.5(4.5)\\ \\15\neq11.25[/tex]

therefore

The legs are not proportional

case E) 11.25m and 3.75m

[tex]\frac{11.25}{4.5}=\frac{3.75}{1.5} \\ \\11.25(1.5)=3.75(4.5)\\ \\16.875=16.875[/tex]

therefore

The legs are proportional

Answer:

  (a) √2

  (b) 1/2

Step-by-step explanation:

(a) The ratio of distances will be the magnitude of the ratio f(z)/(f(z) -z), so will be ...

  |(1+i)z/((1+i)z -z)| = |(1+i)/i| = |1-i| = √(1+1) = √2

___

(b) You want |g(z) -0| = |g(z) -z|, so you have ...

  |(a +2i)z -0| = |(a +2i)z -z|

  |(a +2i)|·|z| = |a-1 +2i|·|z|

Dividing by the magnitude of z and squaring both sides, we have ...

  a^2 +4 = (a-1)^2 +4

  0 = -2a +1 . . . . . . subtract a^2+4 and simplify

  1/2 = a . . . . . . . . . divide by -2, add 1/2

Number of pallets moved in 4.5 hours = 108

converting 4.5 hours in minutes we get,

4*60 + 0.5*60 = 240+30 = 270 minutes

So, 108 pallets were moved in = 270 minutes

1 pallet was moved in = [tex]\frac{270}{108}=2.5[/tex] minutes

As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = [tex]\frac{120}{2.5}= 48[/tex] pallets.

Hence, 48 pallets can be moved before quitting time.

Answer:

The answer is 2.5 minutes; 48 pallets

Step-by-step explanation:

Number of pallets worker moved in a warehouse = 108

Number of hours it takes to do so  = 4.5

Rate at which they require to move one pallet is given by

Number of pallets worker moved in a warehouse = 108

Number of hours it takes to do so  = 4.5

Rate at which they require to move one pallet is given by

4.5/108 x 60 minutes = 2.5 minutes

Now, if the worker will be off the clock in 2 hours ,

So, number of pallets he can move before quitting time is given by

In 4.5 hours, number of pallets they moved = 108

In 1 hour, number of pallets they moved = 108/4.5 = 24

In 2 hours, number of pallets they moved = 24 x 2 = 48

Answer:

[tex]\log_2(ab^3)^{\frac{1}{2}}=\frac{1}{2}[\log_2(a)+3\log_2(b)][/tex].

Step-by-step explanation:

The given logarithmic expression is [tex]\log_2\sqrt{ab^3}[/tex].

We rewrite the radical as an exponent to obtain;

[tex]\log_2(ab^3)^{\frac{1}{2}}[/tex].

Recall that; [tex]\log_a(M^n)=n\log_a(M)[/tex]

We apply this rule to obtain;

[tex]=\frac{1}{2}\log_2(ab^3)[/tex].

We now use the rule: [tex]\log_a(MN)=\log_a(M)+\log_a(N)[/tex]

This implies that;

[tex]=\frac{1}{2}[\log_2(a)+\log_2(b^3)][/tex].

We again apply: [tex]\log_a(M^n)=n\log_a(M)[/tex]

[tex]=\frac{1}{2}[\log_2(a)+3\log_2(b)][/tex].

Henley can draw 7.2 sketches in 3 hours based on the proportion of 12 sketches in 5 hours; however, when rounding to the nearest whole number, she can complete 7 sketches.

The problem at hand is a simple proportion problem where we want to find out how many sketches Henley can make in 3 hours given that she can make 12 sketches in 5 hours. To solve this, we set up a ratio that relates her drawing rate to the time spent drawing:

12 sketches    x sketches

----------- = ------------

 5 hours        3 hours

We can solve for x by cross-multiplying and then dividing by the coefficient of x:

12 sketches [tex]\times[/tex] 3 hours = 5 hours [tex]\times[/tex] sketches

x = ([tex]12 sketches \times 3 hours[/tex]) / 5 hours

x = 7.2 sketches

Therefore, Henley can draw 7.2 sketches in 3 hours. However, since one cannot draw a fraction of a sketch, we round down to the nearest whole number. Henley can thus draw 7 sketches in 3 hours assuming a consistent drawing speed.

Answer:

b. [tex]y=3.9^x[/tex]

Step-by-step explanation:

Remember that the standard exponential function is [tex]y=ab^x[/tex]

where

[tex]a[/tex] is the coefficient

[tex]b[/tex] is the base

If [tex]b>0[/tex], the function is growing

If [tex]0<b<1[/tex] the graph is decaying

We can infer from the graph that the function is growing, so we can discard [tex]y=0.45^x[/tex] and [tex]y=0.73^x[/tex].

Now, to evaluate our tow remaining equations, we are using the test values [tex]x=0[/tex] and [tex]x=1[/tex]:

For [tex]y=1.8^x[/tex]

For [tex]x=0[/tex]

[tex]y=1.8^0[/tex]

[tex]y=0[/tex]

For [tex]x=1[/tex]

[tex]y=1.8^1[/tex]

[tex]y=1.8[/tex]

The graph passes through the points (0,1) and (1, 1.8)

For [tex]y=3.9^x[/tex]

[tex]x=0[/tex]

[tex]y=3.9^0[/tex]

[tex]y=0[/tex]

[tex]x=1[/tex]

[tex]y=3.9^1[/tex]

[tex]y=3.9[/tex]

The graph passes through the points (0,1) and (1, 3.9)

We can see in the graph when [tex]x=1[/tex], [tex]y[/tex] is almost 4, so we can conclude that the correct equation is [tex]y=3.9^x[/tex]

Answer: option c.

Step-by-step explanation:

 To solve this problem you must keep on mind the properties of logarithms:

[tex]ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a[/tex]

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

[tex]ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})[/tex]

Therefore, the answer is the option c.

Answer:

C

Step-by-step explanation:

We can use 3 properties here to write this as single logarithm:

1. Log (a^b) = b Log a

2. Log x + Log y = Log (x*y)

3. Log x - Log y = Log (x/y)

We can use property #1 first to write:

[tex]ln2x+2lnx-ln3y\\=ln2x+lnx^2-ln3y[/tex]

Now we can use property #2 and property #3 to write this as single logarithm:

[tex]ln2x+lnx^2-ln3y\\=ln(\frac{(2x)(x^2)}{3y})\\=ln(\frac{2x^3}{3y})[/tex]

Answer choice C is right.

Answer: [tex]x=\frac{37}{9}[/tex]

Step-by-step explanation:

By the negative exponent rule, you have that:

[tex](\frac{1}{a})^n=a^{-n}[/tex]

By the exponents properties, you know that:

[tex](m^n)^l=m^{(nl)}[/tex]

[tex](m^n)(m^l)=m^{(n+l)}[/tex]

Rewrite 4, 8 and 32 as following:

4=2²

8=2³

32=2⁵

Rewrite the expression:

[tex](2^2)^{(x-7)}*(2^3)^{(2x-3)}=\frac{32}{2^{(x-9)}}[/tex]

Keeping on mind the exponents properties, you have:

[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=32(2^{-(x-9)}[/tex]

[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=(2^5)(2^{-(x-9)})\\\\(2)^{(2x-14)}*(2)^{(6x-9)}=(2^5)(2^{(-x+9)})\\\\2^{((2x-14)+(6x-9))}=2^{(5+(-x+9))}[/tex]

As the bases are equal, then:

[tex](2x-14)+(6x-9)=5+(-x+9)\\\\2x-14+6x-9=5-x+9\\\\8x-23=14-x\\9x=37[/tex]

[tex]x=\frac{37}{9}[/tex]

Answer:

[tex]x=4\frac{1}{9}[/tex]

Step-by-step explanation:

We are given the following linear equation and we are to solve it:

[tex] 4 ^ { x - 7 } \times 8 ^ { 2x - 3 } = \frac { 32 } { x ^ { x - 8 } } [/tex]

Changing the constants to the same base to make it easier to solve:

[tex] 2 ^ { 2 ( x - 7 ) } \times 2^ { 3 ( 2x - 3 ) } = \frac { 2 ^ 5 } { 2 ^ { x - 9 } } [/tex]

[tex]2^{2x-14} \times 2^{6x-9} = 2^{5}(2^{-x+9})[/tex]

[tex] 2 ^ { 2x - 14 + 6x - 9 } = 2 ^ { 5 - x + 9 } [/tex]

[tex] 2 x + 6x - 14 - 9 = 5 - x + 9 [/tex]

[tex]8x+x=14+9+5+9[/tex]

Answer:

f(x) = (x + 6)(x – 2)

Step-by-step explanation:

The roots of a polynomial are the solutions to its factors. This means you can set the factors equal to 0 and the roots are the solution. Working backwards, if the roots are x = -6 and x = 2 then they must have resulted from factors x + 6 and x - 2. This is true since x + 6 = 0 has solution x = -6. And x-2 = 0 has solution x = 2.

So the polynomial has factors (x+6)(x-2). The solution is f(x) = (x + 6)(x – 2).

Answer:

Probability of winning first situation:  0.0793

Probability of winning second situation:  0.0146

You should go with the first option

Step-by-step explanation:

See attached photo for answers.   For this situation you need to identify p-hat, p, q and n.

P-hat, p, and q all stay the same for both situations, only n changes.

p-hat is the proportion of green balls we want, which is 0.7

p = 98/159 = 0.62

q = 0.38 because q = 1 - p, which in this case is q = 1 - 0.62 = 0.38

n = 73 for the first situation, and n = 175 for the second situation

Using the normal probability distribution and the central limit theorem, it is found that:

a)

With 73 draws, there is a 0.0808 = 8.08% probability of getting more than 70% green balls.

With 175 draws, 0.015 = 1.5% probability of getting more than 70% green balls.

b)

Due to the higher probability of getting more than 70% green balls, 73 draws should be chosen.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Central Limit Theorem

Item a:

Out of 73 draws:

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.6203(0.3797)}{73}} = 0.0568[/tex]

The probability of more than 70% green balls is 1 subtracted by the p-value of Z when X = 0.7, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.7 - 0.6203}{0.0568}[/tex]

[tex]Z = 1.4[/tex]

[tex]Z = 1.4[/tex] has a p-value of 0.9192.

1 - 0.9192 = 0.0808

With 73 draws, there is a 0.0808 = 8.08% probability of getting more than 70% green balls.

Out of 175 draws:

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.6203(0.3797)}{175}} = 0.0367[/tex]

Then:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.7 - 0.6203}{0.0367}[/tex]

[tex]Z = 2.17[/tex]

[tex]Z = 2.17[/tex] has a p-value of 0.985.

1 - 0.985 = 0.015.

With 175 draws, 0.015 = 1.5% probability of getting more than 70% green balls.

Item b:

Due to the higher probability of getting more than 70% green balls, 73 draws should be chosen.

3.

     n1 = 8

     n2 = -2

Step-by-step explanation:

1. First problem

We need to Add or subtract the expressions to find the equivalent terms

a) (−2x^2 −4x + 13)+ (12x^2 + 2x −25)

We add together the terms with the same exponent

= (−2x^2 + 12x^2 ) +  (−4x + 2x) + (13 - 25)

= (10x^2 ) +  (−2x) + (-12)

=  10x^2 −2x -12

b) (7x^2 + 4x − 26)− (−7x^2 − 3x + 15)

= (7x^2 + 4x − 26) +  (7x^2 + 3x - 15)

We add together the terms with the same exponent

= (7x^2 + 7x^2 ) +  (4x + 3x) + (- 26 -15)

= (14x^2 ) +  (7x) + (-41)

=  14x^2 + 7x -41

2. Second problem

(5x − 1)(6x^2 + 3x + 7)

We need to multiply to find the equivalent expression\

(5x − 1)(6x^2 + 3x + 7) = (5x)*(6x^2 + 3x + 7) + (-1)*(6x^2 + 3x + 7)

= [(5x)*(6x^2 + 3x + 7)]  + [-6x^2 - 3x - 7]

=  [(5x*6x^2) + (5x*3x) + (5x*7)]  +  [-6x^2 - 3x - 7]

= [(30x^3) + (15x^2) + (35x)]  +  [-6x^2 - 3x - 7]

We add together the remaining terms

= [(30x^3) + (15x^2 - 6x^2) + (35x - 3x)  - 7]

= (30x^3) + (9x^2) + (32x)  - 7

= 30x^3 + 9x^2 + 32x  - 7

Lets use the quadratic formula

Let   y = ax2 + bx + c

a = 1

[tex]\theta=25^o\to\cos25^o\approx0.9063\\\\b=3[/tex]

Substitute:

[tex]\dfrac{3}{c}=0.9063[/tex]

[tex]\dfrac{3}{c}=\dfrac{9063}{10000}[/tex]          cross multiply

PARALLEL slopes always have the same slope no matter what because they are parallel

Answer:

[tex]y=47x-654[/tex]

Step-by-step explanation:

To find the line parallel to the given linear equation, we have to use the same slope, because the condition of parallelism is that they must have the same slope.

So, the slope of the given line is [tex]m=47[/tex], because it's expressed in slope-intercept form, where the coefficient of the variable x is the slope.

Now, we know that they new parallel lines must have a slope equal to 47, and must pass through (14,4). Using this data, we apply the point-slope formula to find the equation of the new line:

[tex]y-y_{1}=m(x-x_{1})\\y-4=47(x-14)\\y=47x-658+4\\y=47x-654[/tex]

The image attached shows the parallelism.

Therefore, the answer is [tex]y=47x-654[/tex]

The last term of this sequence is -229.

The nth term of this sequence is given by:

[tex]a_n=a_1+d(n-1)[/tex]

We use the last term to determine the number of terms in the sequence.

[tex] - 229 = 3 + - 8(n - 1)[/tex]

[tex]- 229 - 3= - 8(n - 1)[/tex]

[tex]- 232= - 8(n - 1)[/tex]

[tex]S_n= \frac{n}{2} ( a_{1} + l)[/tex]

The sum of the first 30 terms is given by:

[tex]S_{30}= \frac{30}{2} ( 3 + - 229)[/tex]

[tex]S_{30}=15( - 226)[/tex]

[tex]S_{30}= - 3390[/tex]

Reducing the equation, we get:

3^(3-3a) = 3^(-2a)

So 3-3a = -2a, a = 3.

The value of the variable 'a' will be 3. Then the correct option is C.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

[tex]7 + 42 \cdot 3^{2 - 3a} = 14 \cdot 3^{-2a} + 7[/tex]

Simplify the equation, then we have

[tex]42 \cdot 3^{2 - 3a} = 14 \cdot 3^{-2a}\\\\3^{2 - 3a} = \dfrac{1}{3} \cdot 3^{-2a}\\\\\left (3 \right )^{2 - 3a } } = (3)^{-1 - 2a}[/tex]

Compare the power of the number 3, then we have

- 1 - 2a = 2 - 3a

3a - 2a = 2 + 1

a = 3

The value of the variable 'a' will be 3. Then the correct option is C.

Answer:

See below  

Step-by-step explanation:

19)

  13² =  4² + AM²

 169 = 16  + AM ²

AM ² = 153

AM =√153 = √(9× 17) = 3√17

sinA = MT /AT  = 4/13

cosA = AM/AT  = (3√17)/13

tanA = MT/AM  = 4/(3√17)   = (4√17)/51

sinT = AM/AT  = (3√17)/13

cosT = MT/AT  = 4/13

tanT = AM/MT = (3√17)/4

20)

10² =  5² + AJ²

100 = 25  + AJ²

AJ² = 75

AJ = √75 = √(25×3) = 5√3

sinA = JT/AT  = 5/10       = ½

cosA = AJ/AT = (5√3)/10 = (√3)/2

tanA = AJ /AJ = 5/(5√3)  = (√3)/3

sinT = AJ/AT = (5√3)/10 = (√3)/2

cosT = AJ/AT = 5/10       = ½

tanT = AJ/JT  = (5√3)/5   = √3
