Answers

Answer 1

Answer:

Hello There!

-22.96 is not an integer.

An integer is any whole number that is positive or negative. A whole number includes 0 and counting numbers so -22.96 would not be considered an integer.

Answer 2

Answer:

Answer:

no it is not an integer

Step-by-step explanation:

nope.

Integers are whole numbers that are not fractions.

this is not the case in -22.96 as the decimal 0.96 constitutes the faction component of the number

The sum of a number ,1/6 of that number ,2 1/2 of that number, and 7 is 2 1/2 find the number

Answers

Let x be the number. If I understand the wording of the problem correctly, then the equation is this: x + (1/6)x + (5/2)x + 7 = 5/2 .

x = - 27/22 or - 1 5/22 if a mixed number is desired.

Step-by-step explanation:

2 sin^2 (x) -5 sin (x) -3=0 I. Rewrite the equation by substituting the expression u in for sin x.

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

III. Use the zero product property to solve the quadratic equation.

IV. Rewrite your solutions to Part III by replacing u with sin x.

V. Solve the remaining equations for x, giving all solutions to the equation.

Answers

we have that

$2sin^(2) x-5sin x-3=0$

I. Rewrite the equation by substituting the expression u in for sin x.

$2u^(2) -5u-3=0$

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

$2u^(2) -5u-3=0$ is equal to

using a graph calculator-----> see the attached figure

$(u-3)*(2u+1)=0$

III. Use the zero product property to solve the quadratic equation.

$(u-3)*(2u+1)=0$

(u-3)=0--------------> u=3

(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5

IV. Rewrite your solutions to Part III by replacing u with sin x.

sin x=3--------> is not the solution (sin x can not be greater than 1)

sin x=-0.50------>is the solution

V. Solve the remaining equations for x, giving all solutions to the equation.

sin x=-0.50

if the sine is negative

then

x belong to the III or IV quadrant

we know that

sin 30°=0.50

the solution for the III quadrant is

x=180°+30°-------> x=210°

the solution for the IV quadrant is

x=360°-30°------> x=330°

Round each number to the nearest tenth what is the best estimate for the answer to 38.94+65.43

Answers

38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down

38.94

The number is 4, so we round down. 38.94 becomes 38.9

65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.

65.43

The number is 3, so we round down. 65.43 becomes 65.4

38.9+65.4= 104.3

If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65

40+65=105

♥ 38.94+65.43=
♥ 104.37
♥ Rounded to the nearest then:
♥ 40
♥ 104.40 is your answer.
♥ All you need to do is round 37.
