Answer:
x = 6
Step-by-step explanation:
I think it's supposed to be
y = x² - 12x + 36
Set the equation equal to zero and solve...
0 = x² - 12x + 36
Now factor. What 2 numbers add to -12, and multiply to 36?
-6 and -6, so our factors are
0 = (x - 6)(x - 6)
So
0 = x - 6, then
6 = x
Answer:
y>0
all positive real numbers
Step-by-step explanation:
the range is the output values
this will always be greater than 0
Range : y>0
Answer:
C. 20480
Step-by-step explanation:
so the equation is (60x3) divided by 15 because there are 3 minutes and 60 seconds in each minute and the bacteria doubles every 15 seconds so when you get your answer (12) that is how many times you will double 5.
Answer:
6=72 cm; 7=15 cm; 8=30 in; 9)56.5 degrees; 10)40 in
Step-by-step explanation:
6) The height of the triangle is 12 cm. The base is around 10 cm. Triangles are 1/2(b)h, so:
1/2(10)=5
5*12=60 cm
72 is closest to this.
7) Volume is l*w*h, so:
2.5*1.5=3.75
3.75*4=15 cm
8) Again, the height is 5 and the base is 12. 1/2(b)h means:
1/2(12)=6
6*5=30 in
9) All triangles have 180 degrees. So first, add the degrees you know:
33.5+90=123.5
Now, subtract that from 180:
180-123.5=56.5
10) Trapezoids can be found by multiplying the height by the smaller base, so:
6*8=40 in
Hope this helped!
