MATH HELP I NEED THE FULL EXPLANATION

olganol [36]

No

$({4}^{11} \times {4}^{1} ) ^{3}$
put 11 for p

${}^{11 + } {}^{1}$
add exponents. base stays the same
$({4}^{12} ) ^{3}$
multiply exponents. base stays same
$12 \times 3$
answer:
${4}^{36}$
His answer is inncorrect becase he added the exponents 12 and 3 instead of multiplying. You multiply exponents when one is raised to another.
for example:
$({2}^{2} ) ^{3 } \\ 2 \times 3 \\ {2}^{6}$
still check internet to make sure if im right.

Write the equation of a line that is perpendicular to y = –x-6and that passes through the point

defon

Answer:

y = x + 5

Step-by-step explanation:

Perpendicularity: Slope is the opposite reciprocal. In this case with it being -1 aka -1/1, the slope will be 1 aka 1/1

Find the opposite reciprocal of the slope

m = -1 = -1/1

so,

m⊥ = 1 as the opposite reciprocal is 1/1

2 - Plug the new slope into y = mx + b

y = mx + b

y = 1x + b

y = x + b

3 - Plug the point values in replacing x and y to get alone and solve for the y intercept, b.

y = x + b

-4 = -9 + b

+9 +9

5 = b

4 - Plug into the values into y = mx + b all together

y = mx + b

y = 1x + 5

y = x + 5

Hope this helps :)

Find "G". Round to two decimal places. G= R+ab/at R=257 a=4.88 b=37.4 t=61.5

givi [52]

Answer:

G ≈ 1.46

Step-by-step explanation:

Given

G = $\frac{R+ab}{at}$ , substitute values

G = $\frac{257 4.88(37.4)}{4.88(61.5)}$

= $\frac{257+182.512}{300.12}$

= $\frac{439.512}{300.12}$ ≈ 1.46 ( to 2 dec. places )
