Two similar pyramids have slant height of 4 and 6.1. Find the scale factor.2. If the volume of the smaller pyramid is 48 meters cubed, what is the volume of the larger pyramid?
Answers
1) Considering that the slant height of those pyramids is 4 and 6, we can find the scale factor by dividing their slant heights:
[tex]\frac{6}{4}=\frac{3}{2}\text{ or 1.5}[/tex]So we can state that the bigger pyramid is larger than the 1st pyramid by a scale factor of 1.5.
2) For the Volume of the Pyramid, we can write out the formula below:
[tex]V=\frac{1}{3}\cdot Ab\cdot h[/tex]Since the scale factor is 1.5 Then we can state that
[tex]\begin{gathered} V=\frac{48}{\frac{3}{2}} \\ V=32 \end{gathered}[/tex]the Volume of the smaller one is by similarity 1.5 or 3/2 times smaller than the larger one.

The function f(x) is shown on the graph.
The graph shows a downward opening parabola with a vertex at negative 3 comma 16, a point at negative 7 comma 0, a point at 1 comma 0, a point at negative 6 comma 7, and a point at 0 comma 7.
What is the standard form of the equation of f(x)?
f(x) = −x2 − 6x + 7
f(x) = −x2 + 6x + 7
f(x) = x2 − 6x + 7
f(x) = x2 + 6x + 7
Answers
Answer:
f(x)= -x^2-6x+7
Step-by-step explanation:
Since the graph opens downward the function for the parabola is going to be negative. This leaves us with two answers.
Now use the remaining possible equations and solve for the vertex.
Using x= -b/2a to solve for the x value of the vertex plug in the values to solve.
a= -1 b= -6 c=7 so, since -6 is already negative plugging it in makes it positive -(-6)/2(-1) = 6/-2 = -3. So x equals negative 3.
Then plug in -3 into the equation to get the y-value.
- (-3)^2 - 6(-3) + 7 = -9 + 18 + 7 = 16 so this confirms the vertex for this equation is (-3,16) so the answer is -x^2-6x+7.
Hope this helped! :)
The vertices of △ABC are A(2, −3), B(−3, −5), and C(4, 1). If (x,y)--> (x-2, y+3), give the vertices of △A′B′C′.
Answers
Answer:
A' = (0, 0)
B' = (-5, -2)
C' = (2, 4)
Step-by-step explanation:
Vertices of triangle ABC:
A = (2, -3)B = (-3, -5)C = (4, 1)Given mapping rule:
(x, y) → (x - 2, y + 3)
This notation tells you that the x-coordinate is translated 2 units to the left, and the y-coordinate is translated 3 units up.
Substitute the coordinates of each point into the mapping rule to find the vertices of triangle A'B'C':
⇒ A' = (2 - 2, -3 + 3) = (0, 0)
⇒ B' = (-3 - 2, -5 + 3) = (-5, -2)
⇒ C' = (4 - 2, 1 + 3) = (2, 4)

118°

44°
11°
Answers
Option C, 59° is correct answer, The angle JIL is equal to 59 degree.
What is angle?
Two rays that have a common terminal and are referred to as the angle's sides and vertices, respectively, make up an angle in Euclidean geometry. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These are what are known as dihedral angles. Another characteristic of intersecting curves is the angle generated by the rays that are perpendicular to the two crossing curves at the point of junction.
Given information in the question,
∠HIL = (6x-7)°
∠JIL = (5x+4)°
The ray IL bisects the ∠HIJ
Since, IL bisects angle HIJ then, angle HIL = angle JIL
So,
6x - 7 = 5x + 4
x = 11
Putting the value of x in given value of JIL to get the angle JIL
∠JIL = (6x-7)°
∠JIL = (6(11)-7)°
∠JIL = 59°
Therefore angle JIL is equal to 59 degrees.

Amy found that she could use the function P(t)=3t^2+5t+8 to model the population of a collection of fruit flies over time, where t is the time in days and P(t) is the number of flies. According to her model, how many flies will there be after 16 days?
A: 8
B: 768
C: 856
D: 2204
Answers
The total number of files after 16 days using the function P(t) = 3t² + 5t + 8 is 856.
A relationship between a group of inputs having different outputs is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output.
The function P(t) represents the population of a collection of fruit flies at a particular time in days.
P(t) is the number of flies and t is the time in days.
Now, consider the function:
P(t) = 3t² + 5t + 8
Therefore, the number of flies after 16 days will be:
When t = 16,
P(t) = 3t² + 5t + 8
P(16) = 3(16)² + 5(16) + 8
P(16) = 3 × 16 × 16 + 5 × 16 + 8
P(16) = 768 + 80 + 8
P(16) = 856
Hence, the number of flies after 16 days will be 856 flies using the function P(t).

Answers
Using ratios, we can conclude that Chris gets 12 sweets.
What are ratios?In mathematics, a ratio shows how many times one number is represented by another. If there are eight oranges and six lemons in a bowl of fruit, the proportion of oranges to lemons would be eight to six. 8:14 for oranges and 6:8 for lemons, respectively, are the ratios of oranges to the total amount of fruit.So, a number of sweets Chris receive:
Alex : Chris = 7:3Let, Chris sweets be 'x' and Alex sweets be 'x + 20'Now, 7:3 = x+20:x, solve as follows:
7:3 = x+20:x7/3 = x+20/x7x = 2x + 607x - 2x = 605x = 60x = 60/5x = 12

the assumption is that this is an arithmetic progression
the nth term of an arithmetic progression is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
use this to find which term 120 is in the sequence
with a₁ = 32 and d = a₂ - a₁ = 40 - 32 = 8 , then
32 + 8(n - 1) = 120 ( subtract 32 from both sides )
8(n - 1) = 88 ( divide both sides by 8 )
n - 1 = 11 ( add 1 to both sides )
n = 12

The required equation of line would be 2y = 5x - 8 which is shown in the given graph.
What is the slope of the line?The slope of a line is defined as the angle of the line.
According to the given figure,
We clearly see that the coordinates of the y-intercept would be (0, -4).
The value of the x-coordinate is 2 when y-coordinate is 1.
Here the line passes through the points (0, -4) and (2, 1).
Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]
x₁ = 0, y₁ = -4
x₂ = 2, y₂ = 1
⇒ y - y₂ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]
⇒ y - 1 = (1 - (-4))/(2 - 0 )[x -2]
⇒ y - 1 = 5/2[x -2]
⇒ 2y - 2 = 5[x -2]
⇒ 2y = 5x - 10 + 2
⇒ 2y = 5x - 8
Therefore, the required equation of line would be 2y = 5x - 8 which is shown in the given graph.

Suppose that R(x) is a polynomial of degree 13 whose coefficients are real numbers. also, suppose that R(x) has the following zeros. answer the following.edit: if possible please double check the answers just to be safe.
Answers
(a) Complex zeros of a polynomial come in pairs.
If a + bi is a zero of a polynomial then its conjugate a - bi is also a zero of the polynomial.
The given complex zeros of R(x) are 1 + 3i and -2i.
1 - 3i is the conjugate of 1 + 3i.
Hence, another zero of R(x) is 1 - 3i
b)
Since the polynomial R(x) is of order 13 then R(x) must have 13 zeros.
The given complex zeros of R(x) are 1 + 3i and -2i. We also know that the conjugates of 1 + 3i and -2i are zeros of R(x). Hence, R(x) has at least 4 complex roots
Hence, the maximum number of real zeros of R(x) is (13 -4).
The maximum number of real zeros of R(x) is 9
c) Let the maximum number of nonreal zeros (complex roots) be n
Complex roots come in pairs. Therefore, n must be even.
Hence, n ≤ 13 - 1 = 12
n ≤ 10
We have been given a real zero of R(x), 3 ( With the multiplicity of 4).
12 - 4 = 8
Therefore,
n ≤ 8.
Hence the maximum number of nonreal zeros of R(x) is 8
