Step-by-step explanation:
The amount of dollars needed to cover the united states is 9.5×10¹⁴ dollars. The correct option is B.
What is an expression?Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that Tyler’s math class found that it would take 2.5×10⁸ dollar bills to cover a square mile area. The surface area of the United States is about 3.8×10⁶ square miles.
The number of dollars will be calculated as below:-
A = [ ( 2.5×10⁸) x (3.8×10⁶) ]
A = ( 9.5 x 10¹⁴ ) dollars.
Therefore, the amount of dollars needed to cover the united states is 9.5×10¹⁴ dollars. The correct option is B.

Two projectiles are shot vertically upward at the same instant.
Projectile A's height in feet, f(t), is represented in the table, where t is the seconds since the projectile was shot off
Projectile B's height at any time t is modeled by the function
h (t)=-16t^2 +96t
How do the times at which the projectiles begin their descents compare?
SEE PHOTO
Projectile B begins its descent 1 seconds before Projectile A does.
What is y-intercept?In Mathematics and Geometry, the y-intercept of any graph or table such as a quadratic equation or function, generally occurs at the point where the value of "x" is equal to zero (x = 0).
By critically observing the table shown in the image attached above, we can reasonably infer and logically deduce the following y-intercept of Projectile A:
y-intercept = (0, 44).
Maximum height = (4, 300).
When t = 0, the y-intercept of Projectile B can be calculated as follows;
h(t) = -16t² + 96t
h(0) = -16(0)² + 96(0)
h(0) = 0.
For the maximum height, we have:
h(t) = -16t² + 96t
h'(t) = -32t + 96
32t = 96
t = 96/32
t = 3
Difference in time = 4 - 3
Difference in time = 1 seconds.

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answer:
8 chickens, 14 sheep needs to be simplified
Step-by-step explanation:
So the chicken has 1 beak and 2 legs and a sheep has 4 legs.
so since there are 8 chickens we know we have 8 beaks
if we mulitply 2 times 8 we get 16
if we mulitply 4 times 14 we get 56
the number of legs is 16+56=72
so we have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simpilfy u get 1:9 as the answer
Verify the identity.

Drag the values to the correct location in the equation. Not all values will be used. Which two values will make the equation true, for y≠0
The two values which will make the given true are 17 and 4.
SimplificationWhat is simplification?By employing different processes, simplification refers to reducing the expression to a simpler form. The mathematical equation is simplified to its closest value using approximation, which is not perfectly accurate.
Simplification for the given equation:Consider the given equation and substitute the vale 17 and 4 in the blank space.
= [tex]17y\sqrt[3]{6y} -14\sqrt[3]{48y^{4} }[/tex]
= [tex]17y\sqrt[3]{6y} -14\sqrt[3]{6*8y^{3} y}[/tex]
= [tex]17y\sqrt[3]{6y} -14\sqrt[3]{6*2^{3} y^{3} y}[/tex]
Further simplifying,
= [tex]17y\sqrt[3]{6y} -14*2y\sqrt[3]{6y}[/tex]
= [tex]17y\sqrt[3]{6y} -28y\sqrt[3]{6y}[/tex]
= [tex]-11y\sqrt[3]{6y}[/tex]
Therefore, the values for which the [tex]17y\sqrt[3]{6y} -14\sqrt[3]{48y^{4} }[/tex] = [tex]-11y\sqrt[3]{6y}[/tex] is 17 and 4.

the tallest building in franklin is two -third the highest of the tallest building in mayville. if the tallest building in mayville is 8013/16feet, find the hihest of the tallest building in franklin
Answer:
[tex]\dfrac{2671}{8}\ \text{feet}[/tex]
Step-by-step explanation:
Given that,
The tallest building in franklin is two-third the highest of the tallest building in mayville.
The tallest building in mayville is [tex]\dfrac{8013}{16}[/tex] feet
We need to find the height of the tallest building in franklin.
Let f is the height of the tallest building in franklin and m is the height of the highest building in mayville.
ATQ,
[tex]f=\dfrac{2}{3}m[/tex]
We have, m = [tex]\dfrac{8013}{16}[/tex] feet
So,
[tex]f=\dfrac{2}{3}\times \dfrac{8013}{16}\\\\f=\dfrac{2671}{8}\ \text{feet}[/tex]
So, the height of the tallest building in franklin is [tex]\dfrac{2671}{8}\ \text{feet}[/tex].

In the last 6 years the population of Manchester, England, has grown at a rate of 0.8% per year to 530,300. If this rate continues, what will be the population in 15 more years? Round your answer to the nearest whole number.
Given parameters:
Current population = 530,300 people
Growth rate = 0.8% per year
Unknown
Population in 15 more years = ?
To solve this problem, we must compound the increase per year.
This implies that we treat the problem like that of a compound interest.
Since we know that population increases by 0.8%,
it is similar to 1 + [tex]\frac{0.8}{100}[/tex] = 1.008 increase
Now the population in 15years will be;
530300 x (1.008)¹⁵ = 597626 people
So, the population after 15yrs is 597626 people
