Use the function f(x) = −16x2 + 60x + to Completely factor f(x).
Pls include steps
Answer: -4x(4x - 15)
Step-by-step explanation:
f(x) = [tex]-16x^{2}[/tex] + 60x
y = [tex]-16x^{2}[/tex] + 60x
=> - ([tex]16x^{2}[/tex] - 60x)
=> -4x(4x - 15)

the value of (a+b)² - (a-b)² is
Answer:
4ab
Step-by-step explanation:
(a+b)^2-(a-b)^2
=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)
=a^2 + 2ab + b^2 - a^2 + 2ab - b^2
=2ab + 2ab

An archery target is shown. The length of a side of the inner square is 6 ft and the length of a side of the outer square is 11 ft. If an arrow
target at random, what is the probability that it hits the shaded region? Round to the nearest percent.
Answer:
The answer is below
Step-by-step explanation:
A square is a quadrilateral (has four sides and four angles). All the sides of a square has equal sides and all the angles of a square are equal with a measure of 90° each.
The area of inner square = length * length = 6 ft * 6 ft = 36 ft²
The area of outer square = length * length = 11 ft * 11 ft = 121 ft²
The probability that the arrow hits the inner square = area of inner square / area of outer square
The probability that the arrow hits the inner square = 36 ft² / 121 ft² = 0.3 = 30%
Answer:
55% i think

Step-by-step explanation:
The sequence 1, 4, 16, 64, 256 shows the similar graph increasing from left to right. Option a is correct.
Sequence which have similar graph as certain geometric sequence increasing from left to right.
It is type of sequence and series that has common and equal ratio between preceding values in series.
Here,
The only geometric sequence seems from observation having increasing from left to right, that implies the curve is also increasing from left to right is 1, 4, 16, 64, 256, having common ratio of 4 with preceding values.
Thus, the sequence 1, 4, 16, 64, 256 shows the similar graph increasing from left to right.

A rancher needs to build a water storage tank for her cattle. The cattle drink 3 cubic meters of water each day and the rancher wants the new tank to hold a 5-day supply of water. If the new tank has a radius of 2 meters, how tall will the tank need to be?
Answer:
The height of the storage tank would be approximately 1.2 m.
Step-by-step explanation:
The cattle drink 3 cubic meters of water each day.
For 5 days,
the cattle would drink = 3 cubic meters x 5
= 15 cubic meters of water
Thus,
The volume of the storage tank = 15 cubic meters
But,
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius and h the height.
So that,
15 = [tex]\frac{22}{7}[/tex] x [tex]2^{2}[/tex] x h
15 = [tex]\frac{22}{7}[/tex] x 4 x h
15 = 12.57h
h = [tex]\frac{15}{12.57}[/tex]
= 1.1933
h = 1.2 m
The height of the storage tank would be approximately 1.2 m.

Function or not a function?
If we want to check that a graph is function or not, we have a way to check by doing these steps.
Draw a vertical line, make sure that a line has to pass through or intercept a graph. See if a line intercepts a graph more than once.If a line intercepts a graph only one point, a graph is indeed a function. Otherwise, not a function but a relation instead. That includes if a line intercepts more than a point which doesn't make a graph a function.
From the graph, if we follow these steps, we will see that a line will only pass or intercept the graph only one point. Hence, the graph is indeed a function. The following graph that is shown is called "Parabola" for a < 0.
AnswerThe graph is a function.

a bicyclist traveled 62 miles in 2 hours.the biker tracked at a constant speed and did not stop for a break.if the biker continues to travel at this rate,which equation can be used to determine y,the total number of miles the biker will travel,in x hours
A.y=62x
B.y=x+62
C.y=31x
D.y=x+31
Answer:
Step-by-step explanation:
if the bicyclist travels 62 miles in 2 h, he travels 62/2=31 miles per hour
y=nr miles
y=31x
choice C
Answer:
C
Step-by-step explanation:
Divide 62 by 2 to get the unit rate (31 miles per hour)
62/2= 31
X is used to show the number of hours. We are trying to determine the number of miles the biker will travel in x hours. So we would need to multiply 31 and "X" or we could write it as "31x"
Hope this helps!
