Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".

Jill’s coach used a computer program to help her improve the distance she can throw a softball. The computer gave a readout of the path of her best throw. The path of this throw was represented by the quadratic equation y = –0.15x2 + 1.3x + 4, where x represents the number of feet the ball traveled and y represents the height of the ball in feet. Use the graphing calculator to graph the equation. At what distance did the ball hit the ground? Round your answer to the nearest hundredth. feet

Answer:
160 square units
Step-by-step explanation:
We need to find the surface area of this figure, which is basically the areas of all the exterior sides.
Looking at the pyramid, we notice that we have 4 congruent triangles and 1 square.
Triangles:
The area of a triangle is denoted as A = (1/2) * b * h, where b is the base and h is the height. Here, the base is 8, so b = 8, and the height is 6, so h = 6. Plug these values in to get the area of one triangle:
A = (1/2) * b * h
A = (1/2) * 8 * 6 = (1/2) * 48 = 24
The area of one triangle is 24 square units, so the area of 4 is 24 * 4 = 96 square units.
Square:
The area of a square is denoted by: A = s * s = s². Here, s = 8, so plug that in:
A = s²
A = 8² = 8 * 8 = 64
The area of the square is 64 square units.
Now add up the areas of the triangles and square:
96 + 64 = 160 square units
The surface area is 160 square units.
Answer:
160
Step-by-step explanation:
Surface area = 4 triangles + square
4(½ × 6 × 8) + 8²
96 + 64
160 units²

What is the volume of a hemisphere with a radius of 29.6 in, rounded to the nearest tenth of a cubic inch?
Answer:
V = 54316.7 in³
Step-by-step explanation:
V = 54316.7463 in³
The solution is, the volume of a hemisphere with a radius of 29.6 in, rounded to the nearest tenth of a cubic inch is, 54289.2 cubic inches.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
a hemisphere with a radius of 29.6 in,
i.e. The radius is 29.6.
now, we know that,
the volume of a hemisphere = 2/3 * pi* r^3
using the formula, we get,
V = 2/3 * 3.14 * 29.6³
=54289.2100267
now, rounded to the nearest tenth we get,
54289.2100267 ≈ 54289.2
The volume of the hemisphere should be 54289.2 cubic inches.

Give 3 angle measures of an obtuse triangle.
Answer:There are many different answers :-) but 100, 40, 40 is one
Step-by-step explanation:
There are quite a few answers, but you need to make sure 1 angle is greater than 90 degrees. The remaining two angles should add up to less than 89 degrees and all 3 angles should total 180 degrees.
i.e. 100, 40, 40
Identify the constant term in 14x + 6y - 5. A. 14 B. 6y C. -5 D. 5
Answer:
D
Step-by-step explanation:
Answer:
C. -5
Step-by-step explanation:
14x and 6y both have variables attached to them
the most basic form for a function like this is ax+by+c
the definition of constant is a fixed value. the reason your constant has to be a solo number, not attached to a variable, is that these variables change the number!! so, -5, the only number that won't change in the function, is the constant.

The safe fluoride-to-water ratio is 0.5 to 1.4 parts per million (ppm) gallons. What is the range in parts of fluoride that could be added to 500,000 gallons of water?
Answer:
250,000 to 700,000 parts
Step-by-step explanation:
For the lower ratio of 0.5, we have to get 0.5 flouride parts/1 gallon of water equivalent to (some fluoride parts)/ (500,000 gallons of water). we can multiply 500,000 by 0.5 to get 250,000 as our lower limit. Similarly, we can multiply 500,000 by 1.4 to get 700,000 as our upper limit
