Explain how am estimate helps you to place the decimal point when multipling 3.7 X 5.1

Answers

Answer 1

Answer: well 3.7×5.1 put the decimals at the end so 37×51=1887 there is 2 decimals so it should be 18.87 you put it back 2 spaces since there's 2 decimals

Answer 2

Answer: Since 3*5=15, then the answer to 3.7*5.1 should be close to that same value. But if you were solving it by hand, and accidentally wrote the answer as 1.887 or 188.7. Estimating helps you know that you placed the decimal in the wrong area, Since the number isn't close to 15.3.7*5.1+18.87

Answers

Answer:

g(- 3) = - 27

Step-by-step explanation:

To evaluate g(- 3) substitute x = - 3 into g(x)

g(- 3) = - 2(- 3)² + 3(- 3) = - 2(9) - 9 = - 18 - 9 = - 27

Passing through (-2, -9) and (6, 7) write in slope intercept form

Answers

Answer:

y = 2x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (6, 7)

m = (7 + 9) / (6 + 2) = 16/8 = 2

y = 2x + c ← is the partial equation

to find c use either of the 2 points

using (6, 7), then

7 = 12 + c ⇒ c = 7 - 12 = - 5

y = 2x - 5 ← equation in slope-intercept form

Dawnie deposited $350 in a savings account earning 2% interest over 3 years.

To solve the problem we have to use the formula I= Principal × Rate × Time (year).

⇒ Given

$350 in a savings account

2% interest over 3 years

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

Let principal amount = $350.00

Let interest rate, 2% per year, or in decimal form, 2/100=0.02.

Let time involved, 3 year(s) time periods.

Calculations

To get the interest rate you have to multiply

350 × 0.02 × 3

The interest is: $21.00
