PLZ HELP ASAP!! Given g(x)=f(x)+k, enter the value for k that transforms the function f into g?
What does k=
Answer:
k = -2
Step-by-step explanation:
firstly, let us examine the kind of transformation that we have
We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)
So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)
This shows a vertical translation to the tune of 2 units in the downward direction
So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)
Accordingly, the value of k in the question is -2
A cereal box is being designed that needs to have dimension ratios of 1:1.5:4.2 and needs to have a volume of 14.49 cubic inches. What is the box's smallest dimension?
Answer:
2.2 inches
Step-by-step explanation:
smallest dimension = (smallest ratio / total ratio) x volume
(smallest ratio = 1
total ratio = 1 + 1.5 + 4.2 = 6.7
(1/6.7) x 14.49 = 2.2 inches

Mike has a fish tank in the shape of a rectangular prism with dimesions of 6 feet by 5 feet by 3 feet. He has a canister that he uses to fill up the fish tank that is in the shape of a cylinder with a diameter of 2 feet and a height of 4 feet. How many tiems will he need to fil up the canister to fill up the tank?
Answer:
7 times
Step-by-step explanation:
To answer this question :
1. the volume of the rectangular prism has to b determined
2. the volume of the cannister has to be determined
3. divide the volume of the rectangular prism by the volume of the cannister
Volume of the rectangular prism = Width X Height X Length = 6 x 5 x 3 = 90ft³
Volume of a cylinder = πr²h
where
h = height
π = 3.14
Diameter = 2r
radius = 2/2 = 1 feet
3.14 x 1 x 4 = 12.56 feet
90 / 12.56 = 7.2 times
Approximating to the nearest whole number gives 7 times
Matrix Math! Find the Product
AxA^T
A
B
C
D
The answer is A.
Use Desmos Matrix Calculator. Enter you Matrix then the equation.
Solve the equation 506x - 92y + 90 = 498 - 4x + 6y
506 x - 92 y + 90 = 498 - 4 x + 6 y
Geometric figure:
line
y = (255 x)/49 - 204/49
510 x - 98 y - 408 = 0
506 x - 92 y + 90 = 6 (y + 83) - 4 x
Real solution:
y = (255 x)/49 - 204/49
Solution:
y = (255 x)/49 - 204/49
Integer solution:
x = 49 n + 40, y = 255 n + 204, n element Z
Solution for the variable y:
y = 51/49 (5 x - 4)
Answer:
Hi! The answer to your question is [tex]x =\frac{49y}{255} +\frac{4}{5}[/tex]

How many bases are there in the triangular pyramid shown below?
Answer:
1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
In a pyramid, there is only one base that touches the ground.
However, in a prism, there are two bases, two of the same ends.
The front of the name of the shape also hints:
If it's an octagonal prism, there are two octagon bases.
If it's a hexagonal pyramid, there is one hexagon base.

A members-only speaker series allows people to join for $19 and then pay $4 for every
event attended. What is the maximum number of events someone can attend for a total
cost of $31
Answer:
The answer is 3 events.
Step-by-step explanation:
I say this because the initial fee is $19, and its $4 per event so 4x3=$12 and $19 + $12 = $31 .
A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 28 centimeters, and the length of the other leg is 22 centimeters.

Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
A. The length of the hypotenuse of the right triangle to the nearest tenth of a centimeter
b. What mistake might the student have made?
A.
she found the difference of the square roots of the lengths of the legs.
B.
she found the sum of the square roots of the lengths of the legs.
C.
she took the square root of the sum of the lengths of the legs.

Answer:
35.6cm
Step-by-step explanation:
it is quite confusing between choice b and c of what the student did wrong.since I'm not understanding it well it just said c but my point is thay student took the sum of the numbers which were the square roots and added and then found the square root and that was a mistake so she wasn't correct .and if I'm wrong also tell me good day.
The graphs of which of these pairs of linear equations intersect at the point (-3, 2)? Select all that apply.
A 6x - y = 15
-3x + 4y = -18
B. 2x + y = -4
3x + 2y = -5
C. X + 8y = 19
4x - 5y = 2
D. 8x + y = 22
-2x - 5y=4
E5x - y = -17
x + 4y = 5
Answer:
Options B and E.
Step-by-step explanation:
We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).
The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.
Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.
A)
6x - y = 15
-3x + 4y = -18
In the first equation we have:
6*(-3) - (2) = 15
-18 - 2 = 15
-20 = 15
This is false, so we can discard option A.
B)
2x + y = -4
3x + 2y = -5
In the first equation we have:
2*(-3) + 2 = -4
-6 + 2 = -4
-4 = - 4
This is true, now let's look at the other equation.
3*(-3) + 2*(2) = -5
-9 + 4 = -5
-5 = - 5
This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.
C)
x + 8y = 19
4x - 5y = 2
In the first equation we have:
(-3) + 8*(2) = 19
-3 + 16 = 19
13 = 19
This is false, then we can discard option C.
D)
8x + y = 22
-2x - 5y=4
In the first option we have:
8*(-3) + 2 = 22
-24 + 2 = 22
-22 = 22
This is false, so we can discard option D.
E)
5x - y = -17
x + 4y = 5
In the first option we have:
5*(-3) - (2) = -17
-15 - 2 = -17
-17 = -17
This is true, now let's look at the other equation:
(-3) + 4*(2) = 5
-3 + 8 = 5
5 = 5
This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.
Then the correct options are B and E.

Determine the scale factor
Using QR and Q'R' as points of reference.
From the attached plot, we have:
[tex]QR = 4\ units[/tex]
[tex]Q'R' = 8\ units[/tex]
The scale factor (k) from [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex]. is:

Calcular la magnitud de la velocidad angular y el período de
una rueda que gira con una frecuencia de 1200 rpm.
Answer:
The magnitude of the angular velocity is 125.66 rad / s and the period is 0.05 seconds.
Step-by-step explanation:
The computation of the magnitude and the period is given below:
First we determine the angular velocity that transforming the revolutions per minute,
So,
ω = (1200 rev / min) × (2π rad / rev) × (1 min / 60s)
ω = 125.66 rad / s
Now, the period is
ω = 2π ÷ T
T = 2π ÷ (125.66 rad / s)
T = 0.05 s
Hence, the angular velocity has a value of 125.66 rad / s and the period is 0.05 seconds.

use variable `c` for number of child tickets
Write an equation that describes this situation.
Answer:
All of their tickets cost $425.00
Step-by-step explanation:
a= adults c=children
$1700 divided by a=4
$1700 divided by c=2
