Answer:

1) 21

2) 28

3) 13

Step-by-step explanation:

According to the word problem, a=7 and b=4.

Now, we just plug in the numbers.

14 + 7 = 21

7 ⋅ 4 = 28

5 ⋅ 4 - 7 = 13

ANYTIME YOU SEE TWO VARIABLES (LETTERS) TOGETHER, THAT MEANS MULTIPLY THEM.

AN EXAMPLE OF THIS IS NUMBER 2.

Answer:

Radius is 2.8 Circumference is 17.584 or 17.6 Rounded to the nearest Tenths 

Step-by-step explanation:

1. Find circumference with the Formula C=πd

C=3.14 x 5.6

C=17.584 or 17.6 Rounded to the nearest Tenths

2. Radius is Always half of the Diameter.

5.6/2 = 2.8

2.8 is your radius.

3. If you want to check you work try the formula C=2πr to see if things checks out.

C=2 x 3.14 x 2.8

C= 17.584 or 17.6 Rounded to the nearest Tenths

Hope this Helps!

What's is the square root of 63

QveST [7]

You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.

$\sqrt{63} = \sqrt{9 \times 7} = \sqrt{9} \times \sqrt{7}$

The square root of 9 is 3 so we can just have $3 \sqrt{7}$ (which just means 3 times the square root of 7).

What is the equation for the line of best fit for statistical chart?(In math)

notsponge [240]

The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
