A football is kicked at 40 yards away from a goal post that is 10 feet high. Its path is modeled by y = -0.03x 2 + 1.6x, where x is the horizontal distance in yards traveled by the football and y is the corresponding height above the ground in feet.
Does the football go over the goal post? How far above or below the goal post is the football? Use two or more complete sentences to explain your answers. (Hint: The unit conversion is built into the given function.)
Answer:
It goes over the goal post by 6 feet
Step-by-step explanation:
The football will be at the same x position as the goal when x = 40. When x = 40, y = -0.03 * 40² + 1.6 * 40 = 16. The height of the goal post can be represented by the equation y = 10. Since 16 > 10, the football goes over the goal post by 16 - 10 = 6 feet.

A teacher took a group of 48 students to the movie theater. They have saved $353 in a fund for the students' tickets. How much money will they have left in the fund if the ticket for each student was $7
Answer:
$17
Step-by-step explanation:
If each ticket is $7 and there are 48 student multiply 7 and 48 to see how much the tickets were in total (336)
Now subtract 353 and 336 to see how much money is left (17)
Answer: -17?
Step-by-step explanation:
because 7*48= 336

(will give brainliest) find the value of x
Answer:
x = 180 - [(180 - 3x) + (180 - 2x)]
Step-by-step explanation:
Start off by finding the angles of the triangle
Angle F = 180 - 3x
The angle across from I (which I will call I) = 180 - 2x
Angle G = 180 - (F + I)
Now that we know what G is, we know what x is because the Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. So pretty much X = G
Therefore x = 180 - (F + I) or otherwise said as:
x = 180 - [(180 - 3x) + (180 - 2x)]

What is the prime factorization of 10? Enter your answer as a product of prime numbers, like 2x3 or as a single prime number, like 17
Answer:
2 × 5
Step-by-step explanation:
We want to split the number 10 into its prime numbers.
A good way to start is divide the number by 2, if it's even. 10 is even, so we can divide by 2.
[tex]10\div2=5[/tex]
So the current factors are 2 and 5. We would keep going if one of these numbers was composite, but 2 and 5 or both prime numbers, so we can end the factorization here.
Therefore, the prime factorization of 10 is 2 × 5.
Hope this helped!
The prime factorization of 10 is 2 x 5.
What is the prime factorization of 10?Prime factorization is when you figure out the prime numbers that you can multiply together to get a certain number.
To figure out the prime factors of 10, we begin by dividing it by the lowest prime number, which is 2. Because 10 can be divided evenly by 2, we can say that 10 is equal to 2 multiplied by 5.
The numbers 2 and 5 are special because they can only be divided by 1 and themselves. This makes them prime numbers. The prime factorization of 10 is the result of multiplying the prime factors 2 and 5 together.

Answer:
[tex] 0.7287[/tex]
Step-by-step explanation:
Let $534.9=a$
Thus, given:
$\log a=2.7287$
Hence:
$\log \Big( \frac{a}{100}\Big)=\log a- \log 100$
$\implies \log \Big( \frac{a}{100}\Big)=2.7287-2=0.7287$
what would it be if the sum of six consecutive even numbers is 130 what would the 2nd number be in the sequence PLZ HELP
Answer:
[tex]\huge\boxed{Second\ Number = 42}[/tex]
Step-by-step explanation:
Let the consecutive even numbers be x,x+2,x+4, x+ 6, x+ 8 and x+10
So, the given condition is:
x+x+2+x+4+x+6+x+8+x+10 = 270
6x + 30 = 270
Subtracting both sides by 30
6x = 270 - 30
6x = 240
Dividing both sides by 6
x = 40
So,
First Number = x = 40
Second Number = x+2 = 40+2 = 42
Third Number = x+4 = 40+4 = 44
Fourth Number = x+6 = 40+6 = 46
Fifth Number = x+8 = 40+8 = 48
Sixth Number = x+10 = 40+10 = 50

Complete each congruency statement and name the rule used. If you cannot show the triangles are congruent from the given information, leave the triangle's name blank and write CNBD for "Cannot be determined" in place of the rule. ∆ANT ≅ ∆_____ by _____
Answer:
The correct answer is;
ΔANT ≅ ΔFLE by the SIde-Side-Side (SSS) rule of congruency
Step-by-step explanation:
The given information are;
Segment TN is congruent ts segment EL
Segment TA is congruent ts segment EF
Segment AN is congruent ts segment FL
Therefore, triangle ΔANT is congruent to ΔFLE by the Side-Side-Side (SSS) rule of congruency
One of the rule used to serve as proof that two or more triangles are congruent, is the Side-Side-Side (SSS) rule of congruency. The Side-Side-Side rule of congruency states that if the dimensions of the three sides of one triangle are equal to the dimensions of the three sides of another triangle, the two triangles are congruent.
Therefore, the correct option is ΔANT ≅ ΔFLE by the Side-Side-Side (SSS) rule of congruency

Find f-l.
f(x) = 4log (x-7)
Answer:
f⁻¹(x) = [tex]2^{\dfrac{x}{4} }[/tex] + 7
Step-by-step explanation:
The inverse of a function reverses the operations performed by the function in the question such if f(x) = y, then we have, f⁻¹(y) = x, which reverses the operation of the first function.
The inverse of a function f(x) = 4·㏒₂(x - 7) is found as follows;
We have;
y = 4·㏒₂(x - 7)
We substitute x for y to get;
x = 4·㏒₂(y - 7) which gives;
x/4 = ㏒₂(y - 7)
[tex]2^{\dfrac{x}{4} }[/tex] = y - 7
y = [tex]2^{\dfrac{x}{4} }[/tex] + 7
Therefore;
f⁻¹(x) = [tex]2^{\dfrac{x}{4} }[/tex] + 7.

What is the value of m in the equation 1/2m-3/4n=16, when n=8?
20
32
44
48
Answer:
44
Step-by-step explanation:
1/2m-3/4n=16 , m when n=8
1/2m-3/4n=16
1/2m - 3/4(8) = 16
1/2m - (8 x 3)/4 = 16
1/2m - (24/4) = 16
1/2m - 6 = 16
1/2m = 16 + 6
1/2m = 22
m = 22 x 2
m = 44
Calculate the height of the cylinder shown.
Answer:
37.3
Step-by-step explanation:
If you want to solve it.
Cylineder Formula: Volume = π(radius)²(height)
Isolate height by diving πr² on both sides.
height = (volume/πr²)
height = (300/π(1.6^2))
Answer:
h = 36.2 cm
Step-by-step explanation:
lets make it short and simple
vol of cylinder + volume of hemisphere = 300 cu.cm.
Vc + Vh = 300 --- eq.1
cylinder radius = 1.6 cm.
since it says NOT TO SCALE
let the radius of hemisphere is the same as cylinder.
vol of cylinder = πr²h
vol of hemisphere = 2/3 πr³
using eq.1
πr²h + 2/3 πr³ = 300
π (1.6²) h + 2/3 π (1.6³) = 300
h = 36.2 cm
check:
Vc + Vh = 300
π (1.6²) 36.2 + 2/3 π (1.6³) = 300
300 cu.cm = 300 cu.cm. ----OK

1. Substitute 3 for "q"
3/3 = 1
q = 3
p = 1
2. Substitute 1 for "q"
3/1 = 3
q = 1
p = 3
When "q" decreased, "p" increased.

Use the table shown in the image! 1. Which equation expresses “y” in terms of “x”? A. y=17x B. y=25x C. x=51y D. x=85y 2. What is the charge for renting a machine for 3.5 hours? A. $51.50 B. $59.50 C. $65.50 D. $86.50
Please include all work!
Answer: 1. A. y=17x
2. $59.50
Step-by-step explanation:
1. In the table , it can be seen that as x increases y increases with the proportionality constant k = [tex]\dfrac{y}{x}=\dfrac{51}{3}=\dfrac{85}{5}=\dfrac{119}{7}=17[/tex],.
Equation of direct variation between x and y : [tex]y=kx[/tex]
Put k= 17 , we get
[tex]y=17x[/tex] , which is the required equation.
So correct option is "A".
2. To find : The charge for renting a machine for 3.5 hours.
Put x= 3.5 in above equation , we get
[tex]y=17(3.5)=59.5[/tex]
Hence, the charge for renting a machine for 3.5 hours is $59.50.
So correct option is "B".
