Answer:
f(x) = (1/5)^x
Step-by-step explanation:
We have
x = 1, f(x) = 1/5
x = 0, f(x) = (1/5)^0 = 1
x = 2, f(x) = (1/5)^2 = 1/25
That means we have
f(x) = (1/5)^x

Raymond used 36 cubes to build the first layer of a rectangular prism. The edge length of each cube was 1 inch. The finished prism had a total of 8 layers. What is the volume of Raymond's prism in cubic inches?
Answers
Answer:
[tex]Volume = 288in^3[/tex]
Step-by-step explanation:
Given
[tex]Base\ Cubes = 36[/tex]
[tex]Layers = 8[/tex]
Required
The volume of the prism
The number of base cubes represents the base area and the number of layers represents the height of the prism.
So, the volume is calculated as:
[tex]Volume = Base\ Cubes * Layers[/tex] i.e Base Area * Heights
[tex]Volume = 36 * 8[/tex]
[tex]Volume = 36in^2 * 8in[/tex]
[tex]Volume = 288in^3[/tex]

2. A given circle has the equation x2+y2−4x−2y+4=1. What is the center of the circle?
A. (1, 2)
B. (−2, −1)
C. (−1, −2)
D. (2, 1)
Answers
Answer:
1) A
2) D
Step-by-step explanation:
1) The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center and "r" is the radius of the circle. With a center of (a,-b) the equation of the circle is (x-a)²+(y+b)²=r² making A the correct answer.
2) Convert from general form into standard form:
Given: x²+y²-4x-2y+4=1
Rearrange: x²-4x+4+y²-2y=1
Set right side equal to 0: x²-4x+4+y²-2y-1=0
Complete the square: x²-4x+4+y²-2y-1+2=0+2
Evaluate: x²-4x+4+y²-2y+1=2
Condense: (x-2)²+(y-1)²=2
Therefore, the center of the circle is D) (2,1)

Answer:

Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
*(a+12b)
a²- 12ab

A spinner and 4 cards are shown below:
A spinner with 5 equal sectors is shown in the figure. The colors Green, Blue, Purple, Yellow, and Red are marked on it. The arrow points at the purple color. Four cards are shown on the right side. The colors Red, Yellow, Blue, and Pink are marked on them.
Jane spins the spinner and selects a card without looking. What is the probability that the spinner stops at purple and a pink card is selected?
1 over 20
1 over 5
1 over 4
9 over 20
Answers
Answer: 1 over 20
Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.
If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)
So if we mutiply 1/4 and 1/5, we get 1/20

The circumference is
yd.
Answers
Answer:
[tex]\boxed {\boxed {\sf 163.28 \ yards}}[/tex]
Step-by-step explanation:
The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.
[tex]c= \pi \times d[/tex]
The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.
d= 52 ydAlso, remember we are using 3.14 for pi.
[tex]\pi[/tex]= 3.14Substitute these values into the formula.
[tex]c= 3.14 * 52 \ yd[/tex]
Multiply.
[tex]c=163.28 \ yd[/tex]
The circumference of the circle is 163.28 yards.
Answer:
[tex]\large\fbox{\purple{\underline{Circumference of circle is 163.28 yards}}}[/tex]
Step-by-step explanation:
In the question we have given
Diameter of circle is 52 yards
And Value of π = 3.14
We know that
Circumference of circle = π × diamter
putting the values
Circumference = 3.14 × 52 yards
by mutiplying we get,
Circumference of circle = 163.28 yards
Therefore, Circumference of circle is 163.28 yards
Three fish are swimming at three different elevations: -1 foot, -5 feet, and - 8 feet. Which fish is closest to the surface of the water? How do you know?
Answers
Answer:
Fish with -1 foot
Step-by-step explanation:
- = under
+= above
If you set your water level to 0 then:
-1 +0 = -1 so the fish is 1 foot under the water level
-5 +0 = -5 do the fish is 5 foot under the water
And the last fish either jumped super high or it was hanging on a fishing line becouse it was 8 feet above the water level
So the fish that was the closes to the water level was the fish with -1

Which equation represents the parent function translated to the right 4 units and stretched by a factor of 5?
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. So, I will solve a general solution, instead.
Let (x,y) be the parent function
First transformation: 4 unit right translation
The rule to this is: [tex](x,y) \to (x + b,y)[/tex]
Where b is the units of translation
i.e. [tex]b = 4[/tex]
So, we have;
[tex](x,y) \to (x + 4,y)[/tex]
Second transformation: Stretch by a factor of 5
The rule to this is: [tex](x,y) \to (x ,ay)[/tex]
Where a is the units of translation
i.e. [tex]a = 5[/tex]
So, we have;
[tex](x + 4,y) \to (x+4,5y)[/tex]
Hence, the transformation from the parent function to the new function is:
[tex](x + 4,y) \to (x+4,5y)[/tex]

What is the volume of sphere?
The volume of sphere is the amount of space occupied, within the sphere. The sphere is defined as the three-dimensional round solid figure in which every point on its surface is equidistant from its centre.
[tex]V=\frac{4}{3}\pi r^3[/tex]
here [tex]r[/tex] is the radius and it is [tex]r=2.6ft[/tex]
So,
[tex]V=\frac{4}{3}\pi r^3\\\\V=\frac{4}{3}(3.14)(2.6)^3\\\\V=\frac{4}{3}(3.14)(17.576)\\\\V=\frac{4(55.18)}{3}\\\\V=\frac{220.72}{3}\\\\V=73.57ft^3[/tex]
Hence, the volume of the sphere is [tex]73.57ft^3[/tex].

Answer:
24°
Step-by-step explanation:
Supplementary angles: angles that add up to 180°
Thus, ∠A + ∠B = 180°
=> (x + 6)° + (7x + 30)° = 180°
=> 8x + 36 = 180
=> 8x = 180 - 36
=> 8x = 144
=> x = 18
∠A = (18 + 6)° = 24°
i need help with this please^^
Answers
Step-by-step explanation:
here's your solution
=> angle 3 and angle 8 are interior angles
we know that sum of both angle is 180°
=> angle 3 + angle 8 = 180°
=> angle 3 + 129° = 180°
=> angle 3 = 180° - 129°
=> angle 3 = 51°
now , angle 3 and angle 1 are vertical angle
hence both angle are equal
=> angle 1 = 51°

Answers
Answer:
c. 172 in^2
I did this!
The surface area of the solid is 176 in².
What is surface area?Surface area is the amount of space covering the outside of a three-dimensional shape.
Given that a solid figure made by joining two cuboids, we need to find the total surface area of the solid,
So, we will find the TSA of lower and upper cuboids and then minus the base area of the upper cuboid as it is a overlapping,
Also, the formula used for TSA of a cuboid = 2(LH + WH + LW)
L = length, W = width and H = height,
So,
TSA = 2(7·3 + 3·5 + 5·7) + 2(4·3 + 3·1 + 4·1) - 1·4
= 2(21 + 15 + 35) + 2(12 + 3 + 4) - 4
= 2 × 71 + 2 × 19 - 4
= 142 + 38 - 4
= 142 + 34
= 176 in²
Hence the surface area of the solid is 176 in².
