Given that we have to factor -3y - 18

Use the distributive property,

a(b + c) = ab + bc

From given,

-3y - 18

Factor out the greatest common factor of 3 and 18

The factors of 3 are: 1, 3

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 3

Factot out 3 from given expression

-3y - 18 = 3( - y - 6)

Or else we can rewrite as,

-3y - 18 = -3(y + 6)

Thus the given expression is factored

The radius of the circle is approximately 7.5 cm, and the corresponding area is approximately 56.25π cm², as calculated using the formulas for circumference and area. Here option C is correct.

1: Find the radius using the circumference formula

We know the circumference C = 157 cm.

We also know the formula for circumference of a circle: C = 2πr, where r is the radius.

Rearranging the formula to solve for r, we get: r = C / (2π).

Substituting C with 157, we get: r = 157 / (2π) ≈ 7.5 cm.

2: Calculate the area using the area formula

Now that we know the radius, we can use the formula for the area of a circle: A = πr², where A is the area.

Substituting r with 7.5, we get: A = π * (7.5)² ≈ 56.25π cm².

Therefore, the area of the circle is 56.25π cm². Here option C is correct.

Answer:

25.4 feet tall

Step-by-step explanation:

254 divided by 10 equals 25.4

The height of the apple tree that you expect an apple tree to be ​25.4 feet.

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

A coast redwood tree is about 10 times as tall as an apple tree.

Let 'x' and 'y' be the height of redwood and apple trees. Then the equation is given as,

y = x / 10

One of the tallest coast redwoods even measured 254 feet tall. Then we have

y = 254 / 10

y = 25.4 feet

Answer:

[tex] {f}^{ - 1} (x) = 3 {x}^{2} - 3[/tex]

Step-by-step explanation:

We want to find the inverse of

[tex] y = \sqrt[3]{ \frac{x}{3} + 1} [/tex]

We interchange x and y to get:

[tex]x= \sqrt[3]{ \frac{y}{3} + 1} [/tex]

We solve for y;

[tex] {x}^{2} = \frac{y}{3} + 1[/tex]

Multiply through by 3

[tex]3 {x}^{2} = y + 3[/tex]

Subtract 1 from both sides:

[tex]y = 3 {x}^{2} - 3[/tex]

Therefore the inverse is

[tex] {f}^{ - 1} (x) = 3 {x}^{2} - 3[/tex]

Answer:

a. - 1 3/4

b. 6

Step-by-step explanation:

For each, plug in the given number to the corresponding variable:

a. When x = -2. Plug in -2 for  x in the given expression:

2^(-2) - 2

Simplify. Note that when a negative sign is located in the power sign, you would do the normal power, and then put the number over 1.

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

Simplify:

1/4 - 2 = - 1 3/4

- 1 3/4, or -7/4 is your answer.

b. When x = 3. Plug in 3 for x in the given expression:

2^(3) - 2

Simplify. First solve the power, then subtract:

2^3 = 2 * 2 * 2 = 4 * 2 = 8

Answer:

b. 4

Step-by-step explanation:

Given f(x) = 4x - 4 and g(x) = x - 1, we can find (f/g)(x) by dividing f(x) by g(x):

(f/g)(x) = (4x - 4)/(x - 1)

Now, substituting x = -4 into the expression

(f/g)(-4) = (4*(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4

Therefore, the correct answer is b. 4.

Given the function g(x) = x - 1, let's solve (f/g)(-4) using the function f(x) = 4x - 4.

To find (f/g)(-4), we need to evaluate the expression (f(x)/g(x)) at x = -4.

First, let's find the value of f(x)/g(x) for any x:

(f/g)(x) = f(x)/g(x) = (4x - 4)/(x - 1)

Now, substituting x = -4 into the expression:

(f/g)(-4) = (4(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4

Therefore, the correct answer is b. 4.

Your answer would be 4000.

The only step needed:

Multiply 400 by 10.

400 ---> 400×10 ---> 4000

The total number of books based on the given percentage will be 20 including 15 paperback books.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Suppose Mr. Sanchez bought a total of x number of books.

75% of x = (75/100)x

This is the paperback thus,

(75/100)x = 15

x = 1500/75 = 20

Thus, the number of total books = 20 including 15 paperback books.

Hence "The total number of books based on the given percentage will be 20 including 15 paperback books".

Width of the rectangle is 4 units

Step-by-step explanation:

Area of the rectangle = length × width

⇒ 20 = x (x + 1)

⇒ 20 = x² + x

⇒ x² + x - 20 = 0

⇒ x² + 5x - 4x - 20 = 0 (Using Product Sum rule to factorize)

⇒ x(x + 5) - 4(x + 5) = 0

⇒ (x + 5)(x - 4) = 0

⇒ x = -5, 4 (negative value is neglected)

x = 4

Final answer:

The solution reveals that the width of the rectangle is 4 units.

Explanation:

The student is asking to find the width of the rectangle when the length is given as the sum of the width and 1 unit, and the area of the rectangle is 20 square units.

To solve this, we can set up an equation using the area formula for a rectangle, A = length * width, where the area (A) is 20 square units.

Let's denote the width as w units.

Then the length can be expressed as w + 1 units. Substituting these expressions into the area formula gives us:

20 = w * (w + 1)

Expanding the right side, we get:

20 = w² + w

This is a quadratic equation, which we can solve by setting it equal to zero:

w² + w - 20 = 0

Factoring the quadratic equation, we find:

(w + 5)(w - 4) = 0

Therefore, w could be -5 or +4. Since a width cannot be negative, the only reasonable solution is w = 4 units.

Thus, the width of the rectangle is 4 units.

Answer:

{ - 9, - 7, - 3, - 1 }

Step-by-step explanation:

To obtain the range substitute the values of x from the domain into f(x)

f(- 2) = - 2(- 2) - 5 = 4 - 5 = - 1

f(- 1) = - 2(- 1) - 5 = 2 - 5 = - 3

f(1) = - 2(1) - 5 = - 2 - 5 = - 7

f(2) = - 2(2) - 5 = - 4 - 5 = - 9

range is { - 9, - 7, - 3, - 1 }

First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.

Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.

Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.

The height of an object off the ground h after t seconds is [tex]h(t)=-16t^2+128t[/tex] and the rate of change of h is 192.

Given data:

The average rate of change of a function over an interval [a,b] is given by the formula:

[tex]R=\frac{f(b)-f(a)}{b-a}[/tex]

Now, the function [tex]h(t)=-16t^2+128t[/tex] represents the height of an object off the ground at time t seconds. We are asked to find the average rate of change of h over the interval [4,8].

So, the value of a = 4 and b = 8.

[tex]h(8)=-16(8)^2+128(8)[/tex]

[tex]h(4)=-16(4)^2+128(4)[/tex]

On simplifying the equation:

[tex]R=\frac{h(8)-h(4)}{8-4}[/tex]

[tex]R=\frac{768}{4}[/tex]

[tex]R=192[/tex]

Hence, the average rate of change of h over the interval is 192 feet per second.

The average rate of change of h over the interval [4,8] is -64 feet per second. This is found by substituting the values of a = 4 and b = 8 into the equation h(t) = -16t² + 128t and into the formula for average rate of change.

To find the average rate of change of h over the interval [4, 8], we use the formula for the average rate of change: (h(b) - h(a)) / (b - a). Here, a = 4 and b = 8.

First, calculate h(a) and h(b) using the given equation h(t) = -16t² + 128t:

Substitute h(a) and h(b) into the formula to get:
(0 - 256) / (8 - 4) =-256/4 = -64.

So, the average rate of change of h over the interval [4, 8] is -64 feet per second.

Step-by-step explanation:

2 x 7 x 7 or in exponential form, 2 x 7². 98 turns into 2 times 49, then 49 turns into 7 times 7.

The prime factorization of 98 is equal to 2 x 7².

The prime factorization of 98 involves breaking it down into prime numbers that multiply together to give the original number, 98.

The process for finding the prime factors of 98 is as follows:

Start with the smallest prime number, 2.

Since 98 is an even number, it is divisible by 2. So, divide 98 by 2 to get 49.

Now, 49 is not divisible by 2, so we try the next prime number, which is 3.

Since 49 is not divisible by 3 either, we move to the next prime number, 5, and so on until we reach 7, which does divide 49.

Divide 49 by 7 to get 7. So, 49 is 7 multiplied by 7, both of which are prime numbers.

Putting it all together, the prime factorization of 98 is 2 × 7 × 7 or 2 × 7².
