The value of the function when the value of x is 5 is 29.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

[tex]f(x)= \left \{ {{x^3 \;\;\;\;\;\; x < -3} \atop {2x^2-9\;\;\;-3\leq x < 4}} \atop {5x+4\;\;\;x > 4}}\right.[/tex]

As the value of the function is to be found when the value of x is 5.

So, we can write the function as,

f(5) = 5x + 4

f(5) = 5(5) + 4

f(5) = 29

The finance charge on the average daily balance for , this 1 month period is $3.45  .

In the question ,

it is given that ,

the daily balance over the period of 1 month = $145

The APR rate of interest = 28.5%

the monthly APR rate of interest = (28.5%)/12 = 2.375%

the finance charge for the 1 month period can be calculated using the formula .

finance charge = (daily average balance)×(monthly rate of interest)

Substituting the values , we get

finance charge = 145 × 2.375%

= 145 × 0.02375

= 3.44375

≈ 3.45

Answer: (0,0)   (12,0)

Step-by-step explanation:

y=4x³-96x²+576x

Let y=0

Hence,

4x³-96x²+576x=0

Divide both parts of the equation by 4:

x³-24x²+144x=0

x(x²-24x+144x)=0

x=0

Thus, (0,0)

x²-24x+144=0

x²-2(x)(12)+12(12)=0

x²-2(x)(12)+12²=0

(x-12)²=0

x-12=0

x=12

Thus, (12,0)

The probability that a teenager selected at random is female and their favourite hobby is watching films is 1/4.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

From the information given, there is a total of 32 teenagers. Of those, 8 are female with a favorite hobby of watching films.

Therefore, the probability will be:

= Female who watch films / Total teenagers

= 8/32

= 1/4.

Step-by-step explanation:

[tex]4x+7=1+2(2x+3)[/tex]

⇒ Our goal is to solve for x. We can do this by moving everything else to the other side of the equation.

⇒ Open up the parentheses:

[tex]4x+7=1+4x+6[/tex]

⇒ Simplify:

[tex]4x+7=4x+7[/tex]

Because both sides are equal, we end up with x = x.

In this case, we can say that all values of x are true.

All values of x are true.

Answer:

[tex]y=-\dfrac{1}{8}x^3[/tex]

Step-by-step explanation:

If a function is symmetrical about the origin, when y is replaced with (-y) and x is replaced with (-x), the resulting function will be equal to the original function.

Original function:

[tex]y=-\dfrac{1}{8}x^3[/tex]

Replace y with (-y) and x with (-x):

[tex]\implies -y=-\dfrac{1}{8}(-x)^3[/tex]

[tex]\implies -y=-\dfrac{1}{8}\cdot -x^3[/tex]

[tex]\implies -y=\dfrac{1}{8}x^3[/tex]

Multiply both sides by -1:

[tex]\implies y=-\dfrac{1}{8}x^3[/tex]

Therefore, as the function is equal to the original function, this function is symmetric with respect to the origin.

Step-by-step explanation:

The number of revolutions = Total distance divided by its circumference

The radius of the tire is 1.167 yards.

A circle is a two-dimensional figure with a radius and circumference of
2πr.

The area of a circle is given as πr².

We have,

The number of revolutions = Total distance divided by its circumference

Total distance = 200 yards

Revolutions = 27.28

A tire is in the form of a circle.

So,

The circumference of the tire.

= 2πr

Now,

27.28 = 200 yards / 2πr

2πr = 200 yards / 27.28

r = 200/(27.28 x 2 x 3.14)

r = 200 / 171.32

r = 1.167 yards.

The radius of the tire is 1.167 yards.

Answer:

Step-by-step explanation:

The given steps describe constructing a parallel line using a compass and straightedge given line  and a point E that is not on line .

Step 1: Draw a line through point E that intersects line , and label the point of intersection, C.

Step 2: Place the point of the compass on C and draw an arc that crosses both lines.

Step 3: Without adjusting the compass width, move the compass to point E and draw an arc that has a similar orientation to the first arc drawn.

Step 4: Set the compass width to where the lower arc crosses the two lines.

Step 5: Move the compass point to the upper arc on the intersection of the arc and line .

Step 6: Draw an arc so it intersects the bottom of the arc. Label the intersection D.

Step 7: Use a straightedge to connect points E and D to form the parallel line .

so the answer is Place the point of the compass on C and draw an arc that crosses both lines

The two possible locations of L are (-2,-1) and (14/3, -5/3).

According to the question,

We have the following information:

JK has endpoints J(-10, 1) and K(2, -2). Point L divides JK into two parts with lengths in a ratio of 2:1.

We know that the following formulas are used to find the coordinates of a point:

x = [tex]\frac{(mx2+nx1)}{(m+n)}[/tex] and x = [tex]\frac{(mx2-nx1)}{(m+n)}[/tex]

y = [tex]\frac{(my2+ny1)}{(m+n)}[/tex] and y = [tex]\frac{(my2-ny1)}{(m+n)}[/tex]

In this case, we have the following values:

x1 = -10 and y1 = 1

x2 = 2 and y2 = -1

m = 2 and n = 1

So, we have:

x = {2*2+1*(-10)}/(2+1)

x = (4-10)/3

x = -6/3

x = -2

For the negative sign:

x = {2*2-1*(-10)}/3

x = (4+10)/3

x = 14/3

x = 4.67

The values of y:

y = {2*(-2)+1*1}/3

y = (-4+1)/3

y = -3/3

y = -1

For the negative sign:

y = {2*(-2)-1*1}/3

y = (-4-1)/3

y = -5/3

y = -1.67

The p-value of this sample proportion is equal to 0.0360.

At the 0.01 (1%) significance level, there isn't enough evidence to conclude that freshmen students study less than 2.5 hours per day, on an average.

For this statistical study, we would use a t-test statistic and the null and alternative hypotheses would be given by:

H₀: p ≥ 150 minutes

H₁: p < 150 minutes

Mathematically, the t-test statistic can be calculated by using this formula:

[tex]t=\frac{x\;-\;\mu}{\frac{\delta}{\sqrt{n} } }[/tex]

Where:

Substituting the given parameters into the formula, we have;

t-test, t = (135 - 150)/(44/√30)

t-test, t = (-15)/8.0333

t-test, t = -1.8672

From the t distribution table, the p-value is given by:

p-value = P(t < -1.8672)

p-value = 0.0360

Since the p-value (0.0360) is greater than the significance level (0.01), we fail to reject the null hypothesis because there is insufficient evidence to claim that the mean time of the freshman students is less than 2.5 hours per day.

Based on the Federal Housing Administration's (FHA) total fixed payments-to-income ratio, Roberto would not qualify for the mortgage loan.

The Federal Housing Administration (FHA) allows 31% of a person's income to settle housing costs (as the front-end ratio) and 43% (as the back-end ratio) towards housing expenses and other long-term debt.

Monthly gross income = $3,500

Monthly payments for Housing:

Monthly mortgage = $1,000

Property taxes = $150

Homeowners insurance premium = $75

Mortgage insurance premium = $75

Total monthly housing costs = $1,300

Other monthly debts per month = $500

Total monthly payments = $1,800

Minimum front-end ratio = 31% = $1,085 ($3,500 x 31%)

Maximum back-end ratio = 43% = $1,505 ($3,500 x 43%)
