There is 7,000 female students, and 5,000 male students. Because, if there was 2,000 more female students then male, you have to find out what two numbers add up to 12,000. (Tip, to make it easier, take away the thousands, like 7+5)
1. This function goes trough 3 points: ( 0,0),(8,0) and (4, -8) so we have to find f(0)=0, f(8)=0, f(4)= -8
f(0)= c=0✔️
f(8)=64 a +8b=0 divide by 4; 16a+2b=0 (1)
f(4)=16a+4b=-8 divide by 4; 4a+b= -2 (2)
From(2)
b=-4a-2
Substitute b in (1)
16 a+2( -4a-2)=0; 16a-8a-4=0; 8a=4
so a=1/2✔️
b=-2-2= -4✔️
The quadratic function is:
f(x)=(X^2)/2 -4x=0
2. This quadratic function goes trough points ( 2,12), (-4,0), (8,0)
The quadratic function is:
f(x)= (-x^2)/3. + 4x/3. +32/3
3. This quadratic function goes trough points ( 2, -6), (-1,0), (5,0)
The quadratic function is:
f(x)=(2x^2)/3. -8x/3. -10/3
4. This function goes trough points (0,2), (-2,0), (4,0)
The quadratic function is:
f(x)=(-x^2)/4. +x/2. +2
Answer:
V = lwh
Step-by-step explanation:
Volume means the amount of space an object takes up.
The volume for a rectangular prism can be found with this formula:
Or simply expressed as:
V = lwh
"l" is the lowercase L for <u>length</u>.
"w" is for the <u>width</u>.
"h" is for the <u>height</u>.
To find the volume, substitute the three dimensions into the formula, and multiply.
Answer:
180-62=118 degrees. :)
Step-by-step explanation:
Step-by-step answer:
Between similar figures, if the ratio between the sides is k, then
- ratio between linear measurements, such as diagonals, perimeter, width, heights, etc, are also linear.
Therefore, if the ratio of the corresponding sides is 1:4, the ratio of their perimeters is also 1:4.
Note:
the ratio of area measurements, or surface areas of similar solids, are proportional to k^2.
Similarly, the ratio of volumes of similar solids are proportional to k^3.
