Answer:

h(x) = –5 |x| + 10

k(x)=1/4(x-4)^2+4

m(x)=1/4 |x-8| +6

Step-by-step explanation:

The given function is:

g(x) = |x + 3| + 4

At y-intercept x=0,

g(0) = |0 + 3| + 4

g(0) = 3 + 4=7

The y-intercept of this function is 7.

We look for the functions with y-intercepts greater than 7.

[tex]f(x)=-2(x-8)^2[/tex]

[tex]f(0)=-2(0-8)^2[/tex]

[tex]f(0)=-128[/tex]

h(x) = –5 |x| + 10

h(x) = –5 |0| + 10=10

[tex]j(x)=-4(x+2)^2+8[/tex]

[tex]j(0)=-4(0+2)^2+8=-8[/tex]

[tex]k(x)=\frac{1}{4}(x-4)^2+4[/tex]

[tex]k(0)=\frac{1}{4}(0-4)^2+4=8[/tex]

m(x)=1/4 |x-8| +6

m(0)=1/4 |0-8| +6=8

Answer with explanation:

The given function is

  g(x)=|x+3|+4

The meaning of Y intercept is the distance between origin and Point where the curve cuts Y axis.

In , g(x), put x=0

g(0)=|0+3|+4

   =3+4

   =7

So, Length of Y intercept =7 unit

2.

f(x)=-2(x-8)²

f(0)=-2×(0-8)²

     = -2 × 64

      = -128

Length of Y intercept =-128 unit

3.

h(x)=-5|x|+10

h(0)=-5 × |0| +10

       =10

Length of Y intercept =10 unit

4.

j(x)=-4(x+2)²+8

j(0)=-4×(0+2)²+8

     =-4 × 4+8

    = -16 +8

    = -8

Length of Y intercept =-8 unit

4.

[tex]\rightarrow k(x)=\frac{1}{4} \times (x-4)^2+4\\\\\rightarrow k(0)=\frac{1}{4} \times (0-4)^2+4\\\\\rightarrow k(0)= 4+4\\\\=8[/tex]

Length of Y intercept =8 unit

5.

[tex]\rightarrow m(x)=\frac{1}{4} \times |x-8|+6\\\\\rightarrow k(0)=\frac{1}{4} \times |0-8|+6\\\\\rightarrow k(0)= 2+6\\\\=8[/tex]

Length of Y intercept =8 unit

⇒ h(x),k(x) and m(x) has y intercept greater than y-intercept of the function g(x) = |x + 3| + 4.

The area of the shaded region between a larger circle with a radius of 4 cm and a smaller circle with a radius of 2 cm is 12π cm². This is calculated by subtracting the area of the smaller circle from the area of the larger circle.

This concerns the area of the shaded area between two circles, one with a radius of two centimetres and the other with a radius of four centimeters.

In order to determine this, we first compute the area of each circle using the formula πr², where r is the circle's radius.

Let's start by calculating the area of the bigger circle: π(4cm)² = 16π cm² is the area.

In a similar manner, we can calculate the smaller circle's area: π(2cm)² = 4π cm² is the area.

The area of the shaded region is equal to the area of the larger circle minus the area of the smaller circle, or area = 16π cm² - 4π cm² = 12π cm².

Answer:

12 cm

Step-by-step explanation:

The total surface area of the cone = area of base + area of curved surface

Subtract the base area from total area, that is

πrs = area - πr²

r is the radius and s the slant height

πrs = 417.8 - (π × 7²) = 263.86

Divide both sides by πr

s = [tex]\frac{263.86}{7\pi }[/tex] ≈ 12 cm

I'm going to assume you're saying 3x to the power of 2. So first, apply the values of the variables to the equation just as shown:

3(-5)^2 - |-2|

So first, do -5 to the power of 2:

(-5)(-5)=25

Then, multiply 3 to 25:

3*25=75

Now, the absolute value of y is the absolute value of -2. The aboslute value of any number is its positive value, so now we are left with 75-2

75-2=73

Answer:

h = 10 m

Step-by-step explanation:

We are given the following formula of the area of a trapezoid:

[tex]A=\frac{1}{2} (b+c)h[/tex]

where [tex]h[/tex] is the height of the trapezoid and [tex]b[/tex] and [tex]c[/tex] are its bases.

Re-arranging the given formula to solve for h:

[tex]A=\frac{1}{2} (b+c)h[/tex]

[tex]2A=(b+c)h[/tex]

[tex]h=\frac{2A}{(b+c)}[/tex]

Finding the height of the trapezoid given the bases 20 m, 7 m and area 135m^2.

[tex]h=\frac{2 \times 135}{(7+20)}[/tex]

h = 10 m

ANSWER

h=10m

EXPLANATION

The given formula is

[tex]A = \frac{1}{2} (b + c)h[/tex]

We multiply through by 2 to get,

[tex]2A =(b + c)h[/tex]We divide both sides by (b+c) to get,

[tex] \frac{2A}{b + c}=h[/tex]

Or

[tex]h=\frac{2A}{b + c} [/tex]

[tex]h=\frac{2 \times 135}{20 + 7} [/tex]

We simplify to get,

[tex]h=\frac{270}{27} [/tex]

Therefore

[tex]h = 10[/tex]

Now if b=20, c=7 and A=135, then,

Answer:

x = -12

Step-by-step explanation:

Step 1: Isolate x

1/4x + x = -12 - 3

Step 2: Combine like terms

5/4x = -15

Step 3: Simplify

x = (-15)(4/5)

x = -12

Answer: -12

Step-by-step explanation:−1 /4  x−12=x+3

Step 1: Subtract x from both sides.

−1 /4 x−12−x=x+3−x

−5 /4 x−12=3

Step 2: Add 12 to both sides.

−5 /4 x−12+12=3+12

−5 /4 x=15

Step 3: Multiply both sides by 4/(-5).

( 4 /−5 )*( −5 /4 x)=( 4 /−5 )*(15)

x=−12

The first option is correct: we have

[tex]\left(k^{\frac{1}{8}}\right)^{-1} = \dfrac{1}{k^{\frac{1}{8}}} = \dfrac{1}{\sqrt[8]{k}},\quad \left(k^{-1}\right)^{\frac{1}{8}} = \left(\dfrac{1}{k}\right)^{\frac{1}{8}} = \dfrac{1}{\sqrt[8]{k}}[/tex]

The second option is also correct, because it simply applies the definition

[tex]k^{\frac{1}{n}} = \sqrt[n]{k}[/tex]

The third option is also correct, because it applies the rule

[tex](a^b)^c = a^{bc}[/tex]

The expressions equivalent to (k^(1/8))^(-1) are (k^(-1))^(1/8) and k^(-1/8), matching options a and c from the given choices. These are determined by correctly applying the exponent multiplication rule.

The student is dealing with an expression involving exponents and radicals, specifically focused on understanding the rules for combining and simplifying these expressions. The expression in question is (k^(1/8))^(-1), which we'll simplify in a step-by-step fashion.

The rule of exponents we need to apply here is (a^m)^n = a^(m*n). When applying this rule to the given expression we get:

(k^(1/8))^(-1) = k^(1/8 * -1)

Simplify the exponent:

k^(1/8 * -1) = k^(-1/8)

So, the equivalent expression is:

k^(-1/8)

Now let's examine the choices given:

8 + 4 (2x+7) = 2 (2+6x), 4 (2x+7) + 8 = 2 (6x+2), (4 x 2x + 4x7) + 8 = 2 (6x+2)

x = 9

difference=3a

so an=-6a+(n-1)3a

=3an-9a

Answer:

Option D. [tex]a_{n}=3an-9a[/tex] is the answer.

Step-by-step explanation:

The given sequence is -6a, -3a, 0a, 3a, 6a...........

Since the given sequence is having a common difference d = -3a - (-6a) = -3a + 6a = 3a

Therefore, the given sequence is an arithmetic sequence.

And for an arithmetic sequence general rule or explicit formula is given by

[tex]T_{n}=a+(n-1)d[/tex]

Where a = first term of the sequence

d = common difference

n = number of term which we have to find

Now we put the values from the given sequence

[tex]T_{n}=-6a+(n-1)3a[/tex]

[tex]T_{n}=-6a+3an-3a[/tex]

[tex]T_{n}=3an-9a[/tex]

Option D. [tex]a_{n}=3an-9a[/tex] is the answer.

Step-by-step explanation:

Look at the picture.

The graph of an exponential function  [tex]f(x)=a^x[/tex], a > 0

is above the x-axis and lie in I and II Quarter.

Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

= 2xy(2x + 3)(2x - 5)

Answer:

Step-by-step explanation:

1)  1

2) 5

3) 2

You are looking for the x values of this "rule". It gives you the y-values so all you have to do is plug the y-values into the rule and solve for x

y = 4 so...

4 = x + 3

4 - 3 = x + (3-3)

1 = x + 0

x = 1

When y is 4 then x is 1

y = 8 so...

8 = x + 3

8 - 3 = x + (3 - 3)

x = 5

When y is 8 then x is 5

y = 5 so...

5 = x + 3

5 - 3 = x + (3 - 3)

2 = x + 0

x = 2

When y is 5 then x is 2

Answer:

a) Samuel has a better credit score, so his interest rate is lower.

Step-by-step explanation:

Alan and Samuel both are same age and make same amount of money.

They both have a 30-year mortgage. But Alan pays 5 percent interest, while Samuel only pays 3.5 percent.

There correct answer here will be - Samuel has a better credit score, so his interest rate is lower.

When a person has a good credit rating, that means he has never defaulted any payment and has always paid his loan on time. He must be a trusted customer for the bank that is why he got a lower interest rate than Alan.

For this case we must evaluate [tex]x = 2[/tex] in each of the inequalities and verify if the inequality is met or not:

Option A:

[tex]6x + 20 <29\\6 (2) +20 <29\\12 + 20 <29\\32 <29[/tex]

It is not fulfilled!

Option B:

[tex]7x-10 <11\\7 (2) -10 <11\\14-10 <11\\4 <11[/tex]

Answer:

37

Step-by-step explanation:

Pamela's age can be repesented with the variable, p .

Pamela is 11 years younger than Jerry. Jerry's age can be represented with the expression p + 11.

So,

Pamela: p

Jerry: p + 11

If their total, combined age is 63, the following equation can be used to represent their ages.

p + (p + 11) = 63

Now, solve.

p + (p + 11) = 63

p + p + 11 = 63

2p + 11 = 63

2p = 52

p = 26

Now, remember that 26 is how old Pamela is. We're looking for Jerry's age.

We established before that Jerry's age can be represented with the expression p + 11.

We know what p is, so substitute the value of p into the equation.

p + 11

26 + 11

37

So, Jerry is 37 years old.

If you'd like to double check your answer, add 37 [Jerry's age] and 26 [Pamela's age] and you get 56.

I hope this helps you!!! :)
