Alright, to start this question we know that 1.25 m/s = 25 N, and we want to find out the acceleration of a 35 N force. What we're going to do for now is focus on the first equation to get a cleaner equation. To help us out a bit, I'm going to change the variables of both parts of the equation, so m/s will be abbreviated as m, and N will be n.

We know that 1.25m=25n, so we can take that information and transform it a bit more. We know that 1.25 can be shown with the fraction 5/4, so we'll use that for now, so 5/4m=25n. now, we can multiply both sides by 4 to get 5m=100n, and then divide both sides by 5 to get a cleaner answer. Now we know that 1m=20n!

Now that we know that 1m=20n, we can divide the 35n in the second part of the equation to see what the acceleration of 35n will be! So 35/25 simplifies to 1.75, which means 35 Newtons of force will create an acceleration of 1.75 m/s, which should be your answer!

A table measures x+4 inches long and 5x+12 inches wide. What is the perimeter of the table?
tangare [24]

Answer:

P = 12x +32

Step-by-step explanation:

The perimeter is found by using the formula

P =2(l+w)

We know the length and the width

P = 2(x+4 + 5x+12)

Combine like terms

P = 2(6x+16)

Distribute

P = 12x +32

xxMikexx [17]

Answer:

7³

Step-by-step explanation:

Using PEMDAS, we see that E (which stands for exponents) comes before M (which stands for multiplication) and A (which stands for addition) so the first operation you should do is 7³.

Y=2(x+1)^2 has how many real roots
oee [108]

The equation y= 2(x+1)^2 has one real root and that is x=-1.

What is real roots of the equation?

    We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation X^2-7x+12=0 is solved, the actual roots are 3 and 4.

Here given,

=> y = 2(x+1)^2

Take y=0 then,

=> 2(x+1)^2=0

=> (x+1)^2=0

=>(x+1)=0

=> x=-1

Hence the given equation has one real root and that is x=-1.

Instructions: Find the measure of the indicated angle to the<br> nearest degree
Artemon [7]

Answer:

? = 57

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos ? = adj/ hyp

cos ? = 14/26

Taking the inverse cos of each side

cos ^-1 ( cos ?) = cos ^-1 ( 14/26)

? = 57.42102961

To the nearest degree

? = 57
