Rewrite the logarithm expression into exponential form

zhannawk [14.2K]

Answer:

$\frac{1}{25}$ = $5^{-2}$

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$ , thus

$log_{5}$ ( $\frac{1}{25}$ ) = - 2, then

$\frac{1}{25}$ = $5^{-2}$

Write the equation of a circle with center (0,−6) and radius 4 in general form.

lions [1.4K]

Answer:

x^2 + (y + 6)^2 = 4^2

Step-by-step explanation:

The general form we need here is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

If the center is at (0, -6) and the radius is 4, then the desired equation is

(x - 0)^2 + (y + 6)^2 = 4^2, or just

x^2 + (y + 6)^2 = 4^2

Find three different ratios that are equivalent to 7:3

Artist 52 [7]

Answer:

14:6

21:9

28:12

Step-by-step explanation:

Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:

7 x 2 = 14

3 x 2 = 6

14:6

7 x 3 = 21

3 x 3 = 9

21:9

7 x 4 = 28

3 x 4 = 12

What is the value of the leading coefficient a, if the polynomial function P(x) = a(x + b)2(x − c) has a multiplicity of 2 at th

kirill115 [55]

If the polynomial function $P(x) = a(x + b)^2(x-c)$ has a multiplicity of 2 at the point (−1, 0) then the factor (x-(-1))=(x+1) twice enters the polynomial representation. So, you have known one part of the left side of the polynomial function that is $P(x) = a(x + 1)^2(x-c)$ .

If polynomial function passes through the point (7,0), then $0 = a(7+ 1)^2(7-c)$ and since $a\neq 0$ you have that c=7.

At last, if polynomial function passes through the point (0,-14), then $-14 = a(0+ 1)^2(0-7)$ and $-14=-7a$ , so a=2.
Answer: a=2.
