What is the volume?
7 yd
10 yd
6 yd
Answer:
210 yd³
Step-by-step explanation:
Volume of a triangular prism
= the area of a triangular base × the height
The area of the base
= (10×7)÷2
= 35 yd²
The volume of the prism
= 35 × 6
= 210 yd³

If f(x) = x + 1, and g(x) = 2x
Answer:
B. (f-g)(x)=4^x-1-2x+11
(f-g)(x) = (4^x-1+6) - (2x-5)
apply like terms while retaining order of operations
6 - (-5) = 11
4^x - 1 - 2x + 11
Step-by-step explanation:
Answer:
f(g(x)) = 2x + 1
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(2x)

-22.8 = 6n check your solution
Answer:
-3.8=n
Step-by-step explanation:
My goal is to get n all by itself, but its multiplied by 6. If I do the inverse operation (which is division) on both sides I will get -22.8/6=n. Now I can just simply combine the like terms and finalize my answer. 6 * 3=18 but -22.8 is a decimal number so my answer will range from around 3.5-3.9. if I divide -22.8/6 I get -3.8. My final answer is n=-3.8
A parabola has the focus at (4,6) and the directrix of Y equals -6
Answer:
y = (x-4)²
Step-by-step explanation:
vertex (h , k)
h = 4 .... axis of symmetry
k = (6 + -6) / 2 = 0 .... midpoint of focus and directrix
equation of parabola: y = (x-4)² y = (x-h)² + k
Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y=-1/3 +4.
Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
y=3x-9

These cones are similar. Find the volume of the smaller cone. Round to the nearest tenth. 2 cm 5 cm Volume=[?]cm^ 3 Volume me = 131 cm ^ 3
Answer:
8.4 cm^3 to the nearest tenth.
Step-by-step explanation:
The ratio of the volumes of the 2 cones is the ratio of the cubes of their radii.
So:
5^3 / 2^3 = 131 / v
v = 2^3 * 131 / 5^3
= 8 * 131 / 125
= 8.384.
The volume of smaller cone is 8.4 cm³
What is Volume of Cone?The volume of a cone formula is given as one-third the product of the area of the circular base and the height of the cone. According to the geometric and mathematical concepts, a cone can be termed as a pyramid with a circular cross-section. By measuring the height and radius of a cone, you can easily find out the volume of a cone. If the radius of the base of the cone is "r" and the height of the cone is "h", the volume of cone is given as V = (1/3)πr²h.
By applying Pythagoras theorem on the cone, we can find the relation between volume and slant height of the cone.
We know, h² + r² = L²
⇒ h = √(L² - r²)
where,
h is the height of the cone,
r is the radius of the base, and,
L is the slant height of the cone.
The volume of the cone in terms of slant height can be given as V = (1/3)πr²h = (1/3)πr²√(L² - r²).
Given:
The ratio of the volumes of the 2 cones is the ratio of the cubes of their radii.
Then,
5³ / 2³ = 131 / v
v = 2³ * 131 / 5³
v = 8 * 131 / 125
v = 8.384 cm³

At a carnival, Hayley gets to spin a prize wheel. It has a radius of 8 inches. What is the prize wheel's area?
Answer:
201.06in^2
Step-by-step explanation:
Use area formula which is pi(r)^2
Answer:
200.96 in.
Step-by-step explanation:
**THE PRIZE WHEEL IS THE SHAPE OF A CIRCLE.**
The formula for area of a circle is: πr² (3.14 × radius × radius).
**3.14 IS COMMONLY USED FOR PI**
According to the word problem, the prize wheel has a radius of 8.
πr² (3.14 × radius × radius)
π8² (3.14 × 8 × 8) = 200.96
Therefore, the area of the prize wheel is 200.96 in.

Ms. Haven recorded the number of homework assignments her students completed
and their test grades. Her findings are shown in the table. Which ordered pair is an
outlier in this data set?
Answer:
(6, 97) is the outlier.
Step-by-step explanation:
When we have a data set:
x: x₁, x₂, x₃, ..., xₙ
y: y₁, y₂, y₃, ..., yₙ
Each one of the pairs (x₁, y₁), (x₂, y₂), etc, is an ordered pair that belongs to the data set.
Usually, these values are distributed in some way that, we assume, is normalized. So if one of these ordered pairs is really different from the others, then that pair is called an "outlier".
In the data set, we have:
Number of homework completed vs Score assigned.
You can see that, as the number of homework completed increases, also does the score
For example, for the smaller number of homework completed, (5) the score is 67, the minimum score.
And as the number of homework completed reaches to 10, the score increases to 90 or 98.
But there is an outlier there, you can see that a student that only completed 6 times the homework, has a score of 97 (one of the largest scores) (this score is more than all the scores for the students with 6, 7, 8 and 9 completed homeworks) so we can conclude that this one is the outlier.
(6, 97) is the outlier.

The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
What is inverse trigonometry?Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The inverse trigonometric expression is given below.
⇒ sin⁻¹(sin 17°)
We know that the value of sin⁻¹(sin θ) is θ.
Then the value of the inverse trigonometric expression will be
⇒ sin⁻¹(sin 17°)
⇒ 17°
Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
