Answer:
[tex]a_{10}=\frac{5^{10}}{2^7} -1[/tex]
Step-by-step explanation:
[tex]a_{n}=a_1 . r^{n}-1[/tex]
Here
[tex]r=\frac{5}{2}[/tex]
[tex]a_1 =8[/tex]
For n=10 (tenth Term)
[tex]a_{10}=8(\frac{5}{2})^{10} -1[/tex]
[tex]a_{10}=\frac{5^{10}}{2^7} -1[/tex]
Item 2
Identify the initial amount $a$ and the rate of growth $r$ (as a percent) of the exponential function $y=25\left(1.2\right)^t$ . Evaluate the function when $t=5$ . Round your answer to the nearest tenth.
a=
r= %
when t=5, y=
Answer:
a = 25
r = 20%
y (5)= 62.2

Find the slope of the line from a graph. Will give brainliest!!!
Answer:
2/1 or 2
Step-by-step explanation:
to find the slope you have to calculate the rise over run, do this by picking two spots on the line that go thourgh the corner of a square. then count the amount up the is your rise then the lateral movement, the is your run.
this means the answer is 2/1 that can be simplified to 2.
(-3,-2). (9. -15)
Slope
answer:
-13/12
Step-by-step explanation:
use the formula to find slope using points
it is: y2-y1/x2-x1
plug in point values into formula
-3 = x1. 9 = x2
-2= y1. -15 = y2
-15-(-2)/ 9-(-3)
-13/12
Answer:
m= -13/12
Explanation:
formula to solve: x1-y1

No, 3
Step-by-step explanation:
6/2
How many times can 3 go into 6?
Answer is 3 times because 2 x 3 is 6.
Answer:
3/1
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 6 and 2 is 2
Divide both the numerator and denominator by the GCD
6 ÷ 2 /2 ÷ 2
Reduced fraction:
3/ 1
Therefore, 6/2 simplified to lowest terms is 3/1.

Simplify the expression:
-3(3 – 06y)
Answer:
18y−9
Step-by-step explanation:
Answer:
-9 - (-18y)
simplified more answer : -9 + 18y
if the 06 is a decimal then: answer: -9 - (-1.8y)
more simplfied answer: -9 + 1.8y
Step-by-step explanation: -3 x 3 = -9
-3 x 6y = -18 y
(if 06 a decimal: -3 x 0.6y = -1.8y)

Sample Response: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).
Which did you include in your response? Check all that apply.
Negate the y-coordinate.
Negate the x-coordinate.
Get the point (–5, –2).

Answer:
Let y be the total earning x be the hours workedand 20 be the hourly rate y=20xMiss Guydan and her friend Alyssa are collecting food for the local food bank. Their goal is to collect 2100 pounds of food. They start with 400 pounds of food donated by a local grocery store. Their goal is to collect 25 pounds of food per day. Write an equation that represent this situation. Define your variables.
Answer: Required equation: 400+25x = 2100
Variable: x = Number of days to donate 2100 pounds.
Step-by-step explanation:
Let x = Number of days.
y = Total pounds of food donated in x days.
Given: Initial amount of food = 400 pounds
Pounds of food donated per day = 25
Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)
y = 400+25x
Their goal is to collect 2100 pounds.
2100 = 400+25x [Substitute y= 2100]
Required equation: 400+25x = 2100
Variable: x = Number of days.

Answer:
A, B, C
Step-by-step explanation:
Original Equation: 5x=45
Dividing by 5 on both sides: 5x/5 = 45/5
The result: x=9
Check: 5(9)=45, 45 = 45.
Thus, the correct order of steps should be A, B, C.

Lesson 3.3 - Calculating Slope from Graphs
Answer:
1. draw a line from the bottom left quadrant to the top right quadrant
2. draw a line from the top left quadrant to the bottom right quadrant
3. draw a horizontal line in any quadrants
4. draw a vertical line in any quadrants
5. Connect to the dots by going up to and right two. The slope will be 1.
6. Connect the dots by going up four and left two. The slope will be -2.
7. Connect the dots by going up for and right one. The slope will be 4.
8. You cannot connect the dots because it's a zero slope, so the slope is 0.

Not understanding this
Answer:
120 yd
Step-by-step explanation:
To find the volume, we have to multiply the length, width, and height. We have 8, 6, and 10 as our length, width, and height. First, let's go with the length and width. 8 times 6 is 48. Since it's a triangle, we have to divide by 2. 48 divided by 2 is 24. Now let's multiply by the height. 24 times 5 is 120, so that will be your volume.
Use the given x and y values to write a direct variation
equation. Enter your answer in the form y = kx.
x = 5, y = 50
The form is y = kx
Replace y and x:
50 = k(5)
Solve for k by dividing both sides by 5
K = 10

A company has 64 employees of whom x are members of a union. How many employees are not union members?
Answer:
To find the number of members that are not part of the union, we take the total number of workers (64) and subtract it with the number of workers that are in a union (x). So because of this, the answer is:
64 - x

A plane descended an average of 200 feet per second for 15 seconds. How far had the plane descended at the end of the 15 seconds?
Answer:
3000 ft
Step-by-step explanation:
If we're going 200 ft per one second, that means, to find the distance after 15 seconds, then we have to multiply:
200 fps (feet per second) x 15 seconds = distance.
Distance = 3000 ft
