Figure ABCD is translated down by 6 units:



Which of the following best describes the sides of the transformed figure A'B'C'D'? (1 point)

Answer:

The measure of angle y is 90°

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

so

m∠y=(1/2)[180°] -----> because the diameter divide the circle into two equal parts

so

m∠y=90°

m∠x=(1/2)[148°]

m∠x=74°

Answer:

Y = 90

Answer:

[A.] and [D.]

Step-by-step explanation:

Before we even solve to see which options are true and false, write the polynomial in descending order.

To do this, break the polynomial into terms.

1. -2xy^5

2. 3x^7

3. -10x^3y^6

4. 8x^6

5. 4

To write this in descending order, look at the exponents or degrees.

We have 5 terms [So A. is already a correct option choice] so look at the exponents or degrees for each term

1. -2xy^5  [degree: 6 (x has an exponent, 1)]

2. 3x^7 [degree: 7]

3. -10x^3y^6 [since there are 2 exponents, add them together (degree: 9)]

4. 8x^6 [degree: 6]

5. 4 [degree: 1 (even though it doesn't look like it, 4 actually has an exponent, 1, along with other numbers like 1, 2, 3, 4, 5 etc.)]

-10x^3y^6 has the largest degree, then 3x^7, then 8x^6 and -2xy^5, and lastly 4.

Now, rewrite the polynomial

-2xy^5 + 3x^7 -10x^3y^6 + 8x^6 + 4 = -10x^3y^6 + 3x^7 + 8x^6 -2xy^5 + 4

We already established A.) is a correct answer.

B.) is not correct since our leading term is -10x^3y^6 and -10 would be the leading coefficent.

C.) Is not correct since the degree of the polynomial is 9, since the highest degree is 9

D.) Is correct since 4 has no variables attached to it

E.) Is not correct since the polynomial was not in descending form, we had to do it for them.

Thus, A.) and C.) are the correct answers.

I hope this helps! Let me know if I did something wrong or you have any questions! Thanks! :)

Answer:

f(x)=-3(x+1)^2+27

Step-by-step explanation:

Forst, simplify the expression by pulling out -3, but leave 24 out.

=-3(x^2+2x)+24

Then complete the square of the equatio inside the parenthesis (remember to subtract from the outside what you add to the inside times -3).

=-3(x^2+2x+1)+24+3

=-3(x+1)^2+27

The equation is now in vertex form.

from that, we now know that the vertex is (-1,27).

Set this equation equal to 0 to find the x intercepts:

0=-3(x+1)^2+27

-27=-3(x+1)^2

9=(x+1)^2

3 and -3=x+1

The Answer is in the picture below...

the area of the pool and deck can be calculated by using the expression [tex]500 + 90x + 4x^2[/tex]

The dimension of the pool are:

25 ft long and 20 ft wide

We know that the deck extends x ft away from every side of the pool.

Thus, the total length of the pool and deck together is 25 + 2x ft, and the total width is 20 + 2x ft

Area of rectangle can be found using the formula:

[tex]Area = length \times breadth[/tex]

Putting in values we get:

[tex](25 + 2x) \times (20 + 2x)[/tex]

On simplifying we get:

[tex](25 + 2x) (20 + 2x) = 500 + 50x + 40x + 4x^2 \\\\(25 + 2x) (20 + 2x) = 500 + 90x + 4x^2[/tex]

Thus the area of the pool and deck can be calculated by using the expression [tex]500 + 90x + 4x^2[/tex] ft²

h divided by eight / h over eight

x plus seven times four

Step-by-step explanation:

Add 6 to both sides

-102 + 6 = -2(6 - 7x)

Simplify -102 + 6 to -96

-96 = -2(6 - 7x)

Divide both sides by -2

-96/-2 = 6 - 7x

Two negatives make a positive

96/2 = 6 - 7x

Simplify 96/2 to 48

48 = 6 - 7x

Simplify 48 - 6 to 42

42 = -7x

Divide both sides by -7

-42/7 = x

Simplify 42/7 to 6

-6 = x

Switch sides

EXPLANATION

If C(a,1) is on the line that passes through A(3, 7), and B(-4, 9), then the three points are collinear.

This implies that, when we find the slope using any two points, we should get the same result.

[tex] \frac{9 - 1}{ - 4 - a} = \frac{9 - 7}{ - 4 - 3} [/tex]

We simplify to obtain;

[tex] \frac{8}{ - 4 - a} = \frac{ - 2}{ - 7 } [/tex]

[tex]\frac{8}{ - 4 - a} = \frac{ 2}{ 7 } [/tex]

We cross multiply to get;

[tex]8 \times 7 = 2( - 4 - a)[/tex]

This implies that,

[tex]56 = - 8 - 2a[/tex]

[tex]56 + 8= - 2a[/tex]

[tex]64 = - 2a[/tex]

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.

These numbers are:

[tex]+30\ and\ -2\\+ 30-2 = + 28\\+ 30 * -2 + -60[/tex]

Firstly to facilitate the conversion we need to convert mph to km/h.

50 m= 0.05 km

1 mph= 0.001 km/h

2 mph= 0.002 km/h

For the girl

D=0.05 km

S= 0.002 Km/h

T= 25 h

For the Boy

D=0.05

S= 0.001

T= 50 h

Final answer is [tex]\frac{80}{3}[/tex].

Step-by-step explanation:

We have been given an infinite geometric series.

Now we need to find it's sum.

common ratio [tex]r=-\frac{1}{5}[/tex].

plug n=1 to get the first term

[tex]a_n=32\left(-\frac{1}{5}\right)^{\left(n-1\right)}[/tex]

[tex]a_1=32\left(-\frac{1}{5}\right)^{\left(1-1\right)}[/tex]

[tex]a_1=32\left(-\frac{1}{5}\right)^{\left(0\right)}[/tex]

[tex]a_1=32\left(1\right)[/tex]

[tex]a_1=32[/tex]

Now plug these values into infinite sum formula

[tex]S_{\infty}=\frac{a_1}{1-r}=\frac{32}{1-\left(-\frac{1}{5}\right)}=\frac{32}{1.2}=\frac{320}{12}=\frac{80}{3}[/tex]

Hence final answer is [tex]\frac{80}{3}[/tex].

The sum of the infinite geometric series given in the problem is 26.6

7.

A geometric series is a sequence of terms in which each term is obtained by multiplying the previous term by a constant ratio. It is a specific type of series where the terms follow a geometric progression.

Formally, a geometric series is expressed as:

a, ar, a[tex]r^2[/tex], a[tex]r^3[/tex], ...

To solve the geometric series sum of the form:

S = a + ar + a[tex]r^2[/tex] + a[tex]r^3[/tex] + ...,

where a is the first term and r is the common ratio, we can use the formula for the sum of an infinite geometric series:

S = [tex]\frac{a}{1 - r}[/tex].

In this case, the given series is:

S = 32[tex]\times \frac{-1}{5}^(^n^ -^ 1^)[/tex],

Comparing this to the standard geometric series form, we can identify that the first term a is 32, and the common ratio r is [tex]\frac{-1}{5}[/tex].

Substituting these values into the formula, we get:

S =  32[tex]\times \frac{-1}{5}^(^n^ -^ 1^)[/tex],

S = [tex]\frac{32}{(1 +\frac{1}{5})}[/tex],

S = [tex]\frac{32}{\frac{6}{5} }[/tex],

S = 32 [tex]\times \frac{5}{6}[/tex],

S = [tex]\frac{160}{6}[/tex]

S = [tex]\frac{80}{3}[/tex] = 26.67.

Therefore, the sum of the given geometric series is 80/3 or approximately 26.67.

Answer:

w = 4 m

Step-by-step explanation:

The volume (V) of a cuboid is

V = lwh ( l is length, w is width and h is height )

Given V = 144 m³, then

lwh = 144 ( substitute l = 3 and h = 12 )

3 × w × 12 = 144

36w = 144 ( divide both sides by 36 )

w = 4

The volume of a rectangular prism is given by the product of its dimension: let w, h, l be the width, height and length of the prism, we have

[tex]V = whl[/tex]

In your case, everything is given except the width:

2. a=2 and b= 3

[tex]\sqrt{648}= \sqrt{2^2.3^3}\\25.4 = \sqrt{108}\\25.4 \neq 10.3[/tex]

So, Option B is incorrect

3. a=3, b=4

[tex]\sqrt{648}= \sqrt{2^3.3^4}\\25.4 = \sqrt{648}\\25.4= 25.4[/tex]

Step-by-step explanation:

Using the rules of logarithms

• log [tex]x^{n}[/tex] ⇔ nlogx

• logx + logy ⇔ log xy

Given

2 log 4 + log 2 + log 2

= log 4² + log (2 × 2)

= log 16 + log 4

= log (16 × 4) = log 64

Answer:

A, log 64

Step-by-step explanation:

your answer A, log 64 is correct. i will explain why below:

2 log 4, log 2 and log 2 have the same bases (10), meaning they are able to be added easier. but before we add, we use the Power Rule of Logarithms on 2 log 4

the Power Rule says that we can move an exponent in a logarithm to the front then solve. this also applies to the reverse, as we can move 2 back as an exponent of 4 and solve

2 log 4 ---> log 4² < simplify the exponent and we get log 16

we can now use the Product Rule of Logarithms where log x + log y = log(xy)

we can use that on the first two terms of the addition

log 16 + log 2 ----> log (16 × 2) = log 32

now we can apply the other log 2 to the rule but instead with log 32

log 32 + log 2 ---> log (32 × 2) = log 64

our answer is log 64
