Write 60/105 in its simplest form.

Answer:

I think that the actions of older people/family members around you greatly influence that thoughts/actions of a younger child. Since Marie looks up to Alice, Marie probably thinks that having a child at such a young age is a good idea. Therefore if Alice gave birth at the age of 15, there is a high chance her younger sister will follow in her footsteps.

Using the line of best fit, it is found that the prediction of the forearm length of a man whose height is of 72 in is of 19.417 in.

It states that the predicted forearm length of a person of height x is given by:

y = -0.2967 + 0.2738x.

In this problem, the height is of x = 72 in, hence:

y = -0.2967 + 0.2738(72) = 19.417 in.

Answer:

17

Step-by-step explanation:

→ f(x) = 3x + 2

→ f(5) = 3(5) + 2

→ 15 + 2

→ 17 is the answer.

Answer:

F(5) = 17

Step-by-step explanation:

to solve, we just need to plug all values of x into 5 as shown

f(x) = 3x + 2
f(5) = (3*5) + 2

then following the format of PEMDAS (explained at footer) we solve the new equation

f(5) = (3*5) + 2
f(5) = 15 + 2
f(5) = 17

therefor F(5) is equal to 17

The PEMDAS format of solving equations:

the term Pemdas stands for the steps involved in solving an equation

The number of miles she drove the van for is 250 miles

From the question, we are to determine the number of miles Shelly drove the van

The given equation which shows the relationship between the number of days she rented the van, d, and the number of miles she drove the van, m is

20d + 0.7m = 235

Now, if she rented the van for 3 days, that is, d = 3

Putting the value of d = 3 into the equation to determine the value of m

We get

20(3) + 0.7m = 235

60 + 0.7m = 235

0.7m = 235 - 60

0.7m = 175

m = 175 / 0.7

m = 250

Hence, the number of miles she drove the van for is 250 miles

The equation that represents the amount saved is T(n) = 3 * (2^n), and the total amount saved in 5 weeks is $186

The statement is given as:

raise $2 to the number of weeks he has been working, multiply it by 3,

Let the number of weeks be n.

So, we have:

T(n) = 3 * (2^n)

For week 1 to 5, we have:

T(1) = 3 * (2^1) = 6

T(2) = 3 * (2^2) = 12

T(3) = 3 * (2^3) = 24

T(4) = 3 * (2^4) = 48

T(4) = 3 * (2^5) = 96

The sum is then calculated as:

Sum = 6 + 12 + 24 + 48 + 96

Evaluate the sum

Sum = 186

Hence, the total amount saved in 5 weeks is $186

Answer:

Period = [tex]\frac{\pi }{4}[/tex]

Amplitude = 4

Step-by-step explanation:

To find the answer, use the form acos(bx - c) + d:

a = -4

b = 8

c = 0

d = 0

The amplitude is the absolute value of a, so:

|a| = |-4| = 4

To find the period, use this equation:

[tex]\frac{2\pi }{b}[/tex]

Replace b with 8 in the formula and solve:

[tex]\frac{2\pi }{8} = \frac{\pi }{4}[/tex]                Simplify

So, the period is equal to [tex]\frac{\pi }{4}[/tex]

Answer:

A coupon for 30%

Step-by-step explanation:

A coupon takes the a certain percentage of a price and subtracts it (a discount). A coupon for 30% off takes 30% of the price which is $60 and subtracts it, same goes for the $20 off coupon. Because a greater percentage is being taken off of the price, the 30% off coupon would save someone more money.

The required negative function h(x) with a y-intercept at "-4" with one solution is x + 4

The y-intercept of an equation is the pint where the x-value of the function is 0, that is;

f(-4) = 0

Since the solution has one solution, hence it will be linear in nature

h(x) = x + 4

This gives the required negative function h(x) with a y-intercept at "-4" with one solution

Step-by-step explanation:

to find the area, we need the radius

The radius(R) is half of the diameter(D)

R = D/2

R = 42/2

R = 21

area of a circle(A) = pi x radius[tex]^{2}[/tex]

A = pi( which most times in a problem, equals 3.14) x 42[tex]^{2}[/tex]

Answer:

Step-by-step explanation:

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

The domain is all real numbers, and the range is all real numbers less than or equal to 4.

The equation of the function is given as:

f(x) = -(x + 3)(x -1)

The above function is a quadratic function, and the domain of a quadratic function is the set of all real numbers

Expand the function

f(x) = -(x² + 3x - x - 3)

f(x) = -(x² + 2x - 3)

Expand

f(x) = -x² - 2x + 3

Differentiate

f'(x) = -2x - 2

Set to 0

-2x - 2 = 0

Add 2 to both sides

-2x = 2

Divide through by -2

x = -1

Substitute x = -1 in f(x)

f(-1) = -(-1 + 3)(-1 -1)

Evaluate

f(-1) = 4

This means that the maximum value of the function is 4

Hence, the domain is all real numbers, and the range is all real numbers less than or equal to 4.
