Answer:

Step-by-step explanation:

since the question does not have a given slope you can just put the point into the point slope formula y-y1 = m(x-x1)

y-5 = m(x-(-2))

y-5 = m(x+2)

since the slope is not given, leave it like that

How many whole numbers are there, whose squares and cubes have the same number of digits?

Naddik [55]

Answer:

there are only 4 whole numbers whose squares and cubes have the same number of digits.

Explanations:

let 0, 1, 2 and 4∈W (where W is a whole number), then

$0^2=0$ , $0^3=0$ ,

$1^2=1$ , $1^3=1$ ,

$2^2=4$ , $2^3=8$ ,

$4^2=16$ , $4^3=64$ .

You can see from the above that only four whole numbers are there whose squares and cubes have the same number of digits

You toss a coin and randomly select a number from 0 to 9 what is the probability of getting tails and selecting 3? 0.25 0.95 0 0

andre [41]

The correct answer is .05

To solve, find the decimal of each of the probabilities:

Flipping Tails: 1/2 ----> .5

Picking 3: 1/10-----> .10

Now, multiply them together:

.5 x .10 = .05

Hope this helps!

A quadrilateral has three angles that measure 90 100 and 120 which is the measurement of the fourth angle

Lesechka [4]

Answer:

The final angle is 50

Step-by-step explanation:

All quadrilaterals have interior angles that add up to 360. So we can subtract these numbers from 360 to get the final angle.

360 - 90 - 100 - 120 = 50
