Solve the following quadratic by
completing the square.
y = x2 + 10x + 10
Answer:
x = -5 - √15 or x = -5 + √15Step-by-step explanation:
[tex]y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}[/tex]

How are finding the volume of a rectangular prism and a triangular prism alike
Answer:
the triangular prism is ⅓ the size of the rectangular prism. they have the same concept equation of:
rectangular prism - length×width×height
triangular prism - ½×length×width×height
they both have to multiply the base and height to find the volume
Answer:
Finding the volume of a rectangular and triangular prism are alike, one way is they use similar formula base x length x height. Another way is They both have rectangle in the prism.

The relationship between the number of years (x) that have passed and the population (y) for a small town is shown in the table.
Population Count Per Year
2 3 4
Number of Years (x)
1
5
6
7
8
Population (y)
1,440 1,728 2,074 2,488 2,986 3,583 4,300 5,160
A regression equation for this data is y = 1, 200(1.2).
Answer:
D. 10,699
Step-by-step explanation:
The given data for the Population Count Per Year is presented as follows;
Number of Years (x); 1, 2, 3, 4, 5, 6, 7, 8
[tex]\begin{array}{ccccccccc}Number \ of \ Years \ (x)&1&2&3&4&5&6&7&8\\Population \ (y)&1,440&1,728&2,074&2,488&2,986&3,583&4,300&5,160\end{array}[/tex]The data regression equation is y = 1,200·(1.2)ˣ
Based on the regression equation for the data, the predicted value of the town's population after 12 years is given by substituting x = 12 as follows;
After 12 years, y = 1,200 × (1.2)¹² ≈ 10,699.32
Therefore, the option which is the best prediction is 10,699.

Step-by-step explanation:
find the length of KN to be 21 through reverse pythagorean theorem and then subtract the square of 21 (441) from the square of 35 (1225) to get 784 and then find the square root of 784. that is the length of LN: 28
can someone pls explain how to solve problems like this?? ty
Answer:
hi so basically you find area the way you normally would, length width etc, and then you also find the area of the triangle inside and subtract that amount from the area you first got from the rectangle. sorry if this doesn't make sense, good luck!

How many ways can 3 different math books, 5 different chemistry books, and 7 different physics books be arranged on a shelf if the books of each subject must be kept together?
The graph shows the distance, y, that a car traveled in x hours:
A graph is shown with the x-axis title as Time in hours. The title on the y-axis is Distance Traveled in miles. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 375 in increments of 75 for each grid line. A line is shown connecting ordered pairs 1, 75 and 2, 150 and 3, 225 and 4, 300. The title of the graph is Rate of Travel.
What is the rate of change for the relationship represented in the graph? (1 point)
A) fraction 1 over 150
B) fraction 1 over 75
C) 75
D) 150
The speed of the car is 75 mph
===========================================================
Explanation:
The four given points on the diagonal line are:
(1,75)(2,150)(3,225)(4,300)Pick any two points from that list of four. I'll pick the first two points. The coordinates are then plugged into the slope formula below
m = (y2-y1)/(x2-x1)
m = (150-75)/(2-1)
m = 75/1
m = 75 so the answer is choice C
The rate of change of 75 means that each time x goes up by 1, y increases by 75.
For each hour that passes, the car has traveled 75 miles. Therefore, the rate of change is 75 miles per hour.
-----------
Note how,
slope = rise/run = (change in y)/(change in x)change in y = change in distancechange in x = change in timespeed = (change in distance)/(change in time)In short, the slope represents the speed of the car. If the line remains the same slope, then the speed is constant.
