Answers

Answer:

64 - .75

64 - .75 = 63.25

have a good day/night

Answer: 63.25 (Decimal) or 63 1/4 (fraction)

Step-by-step explanation: 64 - 3/4. 3/4 is 0.75 in decimal form, so subtracting it would be 63.25 which would be 63 1/4 in fraction form. I don’t think you can simplify it since 1/4 is already at it’s smallest form.

question
(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!

Answers

Answer:

(60-5.8) ÷ 5 - 3² = 1.84 (approx)

Step-by-step explanation:

(60-5.8) ÷ 5 - 3²

First simplify the numbers inside the bracket.

(60-5.8) = 54.2

Now, the equation is in the form of,

54.2 ÷ 5 - 9

Put 54.2 ÷ 5 in a bracket for easy calculation.

(54.2 ÷ 5) - 9

Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84

Subtract 9 from 10.84

10.84 - 9

You will now get the answer as,

1.84 (approx)

Function f is defined by the equation f (x) = 10x + 2. What is the value of f (2)?

Answers

Answer:

f(2) = 22

Step-by-step explanation:

To find f(#), plug the number into each x of the equation.

f(x) = 10x + 2

f(2) = 10(2) + 2

Simplify the parentheses by multiplying.

f(2) = 20 + 2

Add.

f(2) = 22

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k

Answers

Answer:

roots: 1 and 3

k = 3

Step-by-step explanation:

2 roots: p and p+2

(x-p) (x-p-2) = x² - 4x + k

x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k

-2 (p+1) = -4

p+1 = 2

p = 1   ... root 1

p' = 1+2 = 3   ... root 2

k = p² + 2p = 3

check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k
