Answer:
Step-by-step explanation:
-10*9*x^3*x*y^2 = -90x^4y^2
Select the zeros of the function
Answer:
Zeroes are where y=0 (x-intercepts)
I think they are expressed as just the x values since the y value can only be zero, but I could be wrong
the zeroes are at x=-6 and x=-2
so (-6, 0) and (-2, 0)
Paul is growing a rectangular rose garden. His area is 5x2+ 8x +3. What are the dimensions of his rectangle?
Answer:
[tex]Length = 5x + 3[/tex]
[tex]Width = x +1[/tex]
Step-by-step explanation:
Given
[tex]Area = 5x^2 + 8x + 3[/tex]
Required
Determine the dimensions
To do this, we simply factorize the given expression.
[tex]Area = 5x^2 + 8x + 3[/tex]
Expand
[tex]Area = 5x^2 + 5x +3x+ 3[/tex]
Factorize
[tex]Area = 5x(x + 1) +3(x+ 1)[/tex]
Factor out x + 1
[tex]Area = (5x +3) (x+ 1)[/tex]
Area is calculated as:
[tex]Area = Length * Width[/tex]
So:
[tex]Length = 5x + 3[/tex]
[tex]Width = x +1[/tex]
A principal wants to find out if her school needs more bike racks. A survey is taken of 30 students who ride the bus. Why might the sample be biased? Describe in words how a sample could have been done that is more representative of the entire school.
Answer:
The students who ride the bus most likely won't use the bike racks so it doesn't impact them and they probably don't know if they need more bike racks.
Step-by-step explanation:
find the slope and y intercept for this problem: -2y= -16x+8
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m=slope and b=y intercept so we can solve for y from what you were given.
-2y=-16x+8
y=8x-4
So the slope is 8 and the y intercept is -4.
A swimming pool measures 10 feet by 8.5 feet by 5 feet. How many cubic feet of water will the swimming pool hold?
Answer:
425 Cubic Feet
Step-by-step explanation:
Cubic feet is volume meaning that in order to find the volume you must multiply the length, width and the height. The answer is 425
The swimming pool will hold 425 cubic feet of water.
What is the volume of a rectangular prism?The volume of the rectangular prism is defined as the space in three-dimension covered by the rectangular prism having the sides Length, Width, and Height.
To find the volume of the swimming pool in cubic feet, we need to multiply the length, width, and height of the pool:
The volume is calculated as,
Volume = length x width x height
Volume = 10 ft x 8.5 ft x 5 ft
Volume = 425 cubic feet
Therefore, the swimming pool will hold 425 cubic feet of water.

PLLLZZ HHEELLPPP! QUESTION IS BELOW!
Answer:
32°Step-by-step explanation:
The two given angles are complementary, it means they add to 90°Find x:
2x + 10 + x + 8 = 903x + 18 = 903x = 72x = 24Find Y:
m∠Y = x + 8 = 24 + 8 = 32°Write a linear equation in slope- intercept form given 2x +5y =35
Answer:
(0,−7)
Explanation:
To find the y-intercept of an equation, set x equal to 0 and solve: In the case of 2x−5y=35, let's replace all instances of x in the equation with 0 and solve for y: 2(0)−5y=35−5y=35−5y−5=35−5
y=−7
Thus, the y-intercept is at (x y)=
(0,−7).

Answer:
Angle C = 142 degrees
Step-by-step explanation:
A+B = 90
B+C = 180
Rearrange first equation to get B = 90-A
Plug this into the second equation:
90-A + C = 180
C = A + 90
Plug in A, C = 52 + 90 = 142

The set of data below represent the number of runs scored by a youth baseball team over the course of a season.
Team: 4, 8, 5, 12, 3, 9, 5, 2 Which set of statements about the data is true?
1)Mean < Standard Deviation
2)First Quartile < Standard Deviation
3)Median > Mean
4)Mean > Standard Deviation
The correct answer will be option (3) Median > Mean
ConceptFirst we will find the mean, median and standard deviation of given dataAfter finding mean, median and standard deviation we will compare them to find the correct answerHow to solve this problem?The steps are as follow:
The runs scored by youth baseball team over the course of a season is : 4, 8, 5, 12, 3, 9, 5, 2Mean is given as follow:[tex]x \: = \frac{4 + 8 + 5 + 12 + 3 + 9 + 5 + 2}{8} \\ x = 6[/tex]
So the mean will be 6Arranging the given observation 2,3,4,5,5,8,9,12To find the median the total number observation is 8 which is even so formula to find median will be:[tex][tex]m = \frac{ { (\frac{n}{2}) }^{th} obs + ( { \frac{n}{2} + 1)}^{th} obs }{2} \\ m= \frac{ { (\frac{8}{2}) }^{th} obs + ( { \frac{8}{2} + 1)}^{th} obs }{2} \\ m= \frac{ { (4) }^{th} obs + ( { 5)}^{th} obs }{2} \\ m= \frac{ { 5} + 5}{2} \\ m = 5[/tex][/tex]
So the correct answer will be option (3) Median > Mean

-5 = 53
-1 = 13
0 = 3
1= -7
Step-by-step explanation:
Not sure if this is right, but all I did was plugged -10 X + 3 into the Y = on my calculator and then graphed and checked the table, I looked at the x value and then the Y.
Step-by-step explanation:
given equation :- y = -10x + 3
1)when x = -5
y = -10x + 3
y = -10 (-5) + 3
= 50 + 3
= 53
2)when x = -1
y = -10x + 3
y = -10(-1) + 3
= 10 + 3
= 13
3) when x = 0
y = -10x + 3
y = -10(0) +3
= 0+ 3
= 3
4) when x = 1
y = -10x + 3
y = -10(1) +3
= -10 + 3
= -7
