Answer:

1/784

Step-by-step explanation:

do you mean 4^-2? when using negative exponents we set it to 1 over the coefficient to the power of the exponent, so it'd be 1/4^2 × 1/7^2 or 1/16*1/49 or 1/784

I need a. Correct answer I will mark brainliest
Otrada [13]

Answer:

Option (A)

Step-by-step explanation:

By satisfying the equation of a function 'f' by each coordinates given in the options we can get the point which lies on the graph of f(x) = 2\times (5)^x

Option (A). (1, 10)

f(1) = 2\times (5)^1

10 = 10

True.

Therefore, point (1, 10) lies on the graph.

Option (B). (0, 10)

f(0) = 2\times 5^0

10 = 2

Not true.

Therefore, point (0, 10) doesn't lie on the graph.

Option (C). (10, 1)

f(10) = 2\times 5^{10}

1 = 19531250

Not true.

Therefore, point (10, 1) doesn't lie on the graph.

Option (D). (0, 0)

f(0) = 2\times 5^0

0 = 2

Not True.

Point (0, 0) doesn't lie on the graph.

Option (A) will be the answer.

-1.3n =7.8 need help​
xxMikexx [17]

Hey there!

-1.3n = 7.8

First, you have to DIVIDE both sides by -1.3

-1.3n / -1.3 = 7.8 / -1.3

Cancel out: -1.3 / -1.3 because it gives you the value of 1

Keep: 7.8 / -1.3 because it gives us the value of n

7.8 ÷ -1.3 = -6

Thus, n = -6 ✅

Good luck on your assignment and enjoy your day!

Help me please, thank you
nexus9112 [7]

Answer: 25%

Step-by-step explanation: You add all the numbers you are given and you get 40 then take the number from the blue which is 16 then subtract 16 from 40 and you get 24, since 24 is very close to 25 that's how you get 25%

It could also be 40% because you added all the numbers together

Hope this helps :)
