Mathematics
1 answer:
Alex777 [14]3 years ago
5 0

Answer:

  A.  5^20 x 7^40

Step-by-step explanation:

The exponent outside applies to each factor inside parentheses. The rules of exponents say ...

  (a^b)^c = a^(b·c)

so, you have ...

  (5^2\times 7^4)^{10}=5^{2\cdot 10}\times 7^{4\cdot 10}=5^{20}\times 7^{40}

Write an equation of a parabola that opens to the left, has a vertex at the origin, and a focus at (–9, 0.
Georgia [21]
The standard equation of parabola:

(y-k)²=4p(x-h), with:

a) vertex = (h,k)

b) focus = (h+p, k)

c) directrix = (x=h-p)


Since this parabola has a vertex at (0,0) that means h=k=0

Hence the equation becomes: y²=4px, let's calculate p:
focus is given (-9,0) Remember h+p = -9 & since h=0, then p= -9
===> y²= - 36x

Gabriel has 15 5/8 pound of clay. He will use 7/10 pounds to make each bowl. After making 8 bowls, Gabriel wonders how many more
Pie
You would begin by multiplying 7/10 by 8 to get 5 3/5. then you would subtract 5 3/5 from 15 5/8 to get the remaining amount of clay after the eight bowls (401/40). lastly, divide the remainder of the clay by 7/10 to get the number of bowls that could be made with it - which is 14. the actual answer has a decimal, but you must have a whole number in order to make an entire bowl. you can check this by multiplying 7/10 by 22 (for the total number of bowls) and you get 15 2/5
