Moe painted the lid of a barrel. The circumference of the lid is 32 inches. Which
measurement is closest to the area of the lid in square inches?

Answers

Answer 1

Answer:

A ≈ 81.487 in²

Step-by-step explanation:

We know that circumference is C = 2πr, where r is the radius.

So,

C = 2πr

32 = 2(3.14)r

[tex]r=\frac{32}{2(3.14)}[/tex]

r ≈ 5.093 in

We also know that the formula for the area of a circle is A = πr², so:

A = πr²

A = (3.14)(5.093)²

A ≈ 81.487 in²

Which r-value suggests a weak negative correlation?
A. r = 0.13475
B. r = 0.95768
C. r = -0.13475
D. r = -0.95768

Answers

Answer:

r = -0.13475

Step-by-step explanation:

Here, we want to select a value for a weak negative correlation

When a correlation is week, its value is usually less than -0.5

In this case, we have our correct answer as r = -0.13475

Which equation can be simplified to find the inverse of y = 2x²?
O1/y=2x²
Oy=1/2x²
O-y= 2x²
O x= 2y²

Answers

Answer:

y=1/2x²

Step-by-step explanation:

y=2x-²

y=1/2x²

The equation can be simplified to find the inverse of y = 2x² is y=1/2x², the correct option is B.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Equation y = 2x²

Now,

To find the inverse of a function, you need to swap the x and y variables and solve for y. So, the equation that can be simplified to find the inverse of y = 2x² is x = 2y². You can simplify it by dividing both sides by 2 and taking the square root of both sides. The inverse function is y = ±√(x/2).

Therefore, by the equation the answer will be y=1/2x²

A telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members. The company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan. The number of phone subscribers x months after the plan was launched is modeled by the function below.

Answers

Answer:

450 x (1 + 0.5) ^ X = Phone subscribers

Step-by-step explanation:

Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:

450 x (1 + 0.5) ^ X = Phone subscribers

So, for example, in 3 months, the number of subscribers would be the following:

450 x (1 + 0.5) ^ 3 = 1,518.75

Thus, in 3 months, the company would have 1,518 subscribers.

Step-by-step explanation:

The height of the swipe card is given by :

[tex]h(t)=-3t^2+15t+18[/tex] .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

[tex]\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s[/tex]

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

[tex]h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet[/tex]

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.

Answers

Answer:

[tex]\Huge\boxed{B.18.610}[/tex]

Step-by-step explanation:

Hello There!

We can find y by using trigonometric ratios

sine, cosine and tangent

[tex]tan= \frac{opposite}{adjacent}[/tex]

the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35

so...

[tex]tan28=\frac{y}{35}[/tex]

now we solve for  y using basic algebra

we want to isolate the variable (y) using inverse operations

to get rid of the 35 we multiply each side by 35

[tex]\frac{y}{35} =y\\tan28*35=35tan28[/tex]

now we let the calculator do the rest of the work

[tex]35tan(28)=18.60983011[/tex]

*round to the nearest thousandth*

we're left with

y = 18.610

hence your answer is B

Step-by-step explanation:

Bc i just did on edge

The pair of equations below is a result of constructing the altitude, h, in Triangle ABC is A; sin C = h/a and sin A = h/c.

What are trigonometric identities?

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We know:

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]

So from the attached figure;

sin C = h/a

sin A = h/c

These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms;

h = a (sin C)

h = c (sin A)

Thus, option A is correct pair.
