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 a quadratic function in standard form with zeros 5 and 6

N76 [4]

Answer:

${x}^{2} - 11x +30$

Step-by-step explanation:

Zeros = 5 & 6

Let the variable of the quadratic function be x

Therefore, (x - 5) & (x-6) are factors

$(x - 5)(x - 6) \\ \\ = {x}^{2} - (5 + 6)x + ( - 5)( - 6) \\ \\ = {x}^{2} - 11x +30 \\ is \: the \: required \: quadratic \: \\function.$

Tina wrote mathematical expressions for five statements. Her work is shown. Statement Tina's Expressions A The product of

Setler [38]

Answer:

See explanation

Step-by-step explanation:

<u>Linear</u> expression is usually an expression of 1st degree.

A. The product of a number and seven $=7\cdot n=7n$

Correct, linear

B. The sum of three consecutive numbers.

Let the smallest number be n, the next number is n + 1 and the last number is n + 2. Then their sum is

$n+(n+1)+(n+2)$

Correct, linear

C. The square of a number times three.

Let the number be n, then its square is $n^2$ and the square of a number times three is

$n^2\cdot 3=3n^2$

Correct, nonlinear

D. Twice the sum of a number and 8.

If the number is n, then the sum of the number anf 8 is n + 8. Twice the sum is

$2\cdot (n+8)=2(n+8)$

Incorrect, linear

E. The cube of a number divided by two.

If the number is n, then its cube is $n^3.$ The cube of the number divided by 3 is

$n^3\div 3$

Correct, nonlinear

2x(8+7)-6/2x(9-3) evaluate

Katarina [22]

Ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do

PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction

parethasees simplify first
(8+7)=15

(9-3)=6

now we have
2x(15)-6/2x(6)
multiply
2x15=30

6/2x6=36/2=18

now we have
30-18
12

answer is 12
