Find two numbers whose sum is 8 and whose product is 17. Show all steps.

Answers

Answer:

See the solution below

Step-by-step explanation:

Find two numbers whose sum is 8 and whose product is 17. Show all steps.

Given data

Let the first number be x

and the second number be y

so

x+y= 8---------1

x*y= 17---------2

from 1

x= 8-y

put the value of x in 2

(8-y)*y= 17

8y-y^2= 17

collect like terms

y^2-8y+17= 0

Let us check the discriminant

y=  √b^2-4ac

y=   √-8^2-4*1*17

y= √64-4*1*17

y= √64-68

y= √-4

Hence the problem has no real solution because the discriminant is negative

Answer:

38

Step-by-step explanation:

A triangle is 180 degrees.

You have to add 99 and 43 first.

99 + 43 = 142

You then subtract 142 from 180 to find the missing angle.

180 - 142 = 38

how to multiply fractions

Answers

For example,

[tex]\frac{1}{2} *\frac{1}{2}[/tex]

They both do have the same denominator, so we can multiply them.

We need to multiply the numerators.

Next, multiply the denominators.

We then get:

If the denominators are not the same, find the LCD (Least Common Denominator) of the two fractions. Then, follow above.

The measures of three sides of a triangle are 7 inches, 9 inches and 2 inches. Determine whether the triangle is a right triangle.

Use pythagorean theorem.
2^2 + 7^2 should equal 9^2 (81), but instead equals 53, therefore, the triangle is not a right angle.

PLEASE ANSWER WILL GIVE POINTS!!!!!!!!!!!!!

Answers

Answer:

1) 27.374

2)9.177

Step-by-step explanation:

1) To get the value of x , we use the appropriate trigonometric ratio

From what we are given;

we have the hypotenuse ( the side facing the right angle) and the adjacent

The trigonometric identity to use here is the cos

The cos of an angle is the ratio of the adjacent to the hypotenuse

cos 64 = 12/x

x = 12/cos 64

x = 27.374

2) Here, we are given the hypotenuse and the opposite

The trigonometric ratio to use here is the sine

the sine of an angle is the ratio of the opposite to the hypotenuse

thus, we have it that;

sin 35 = x/16

x = 16 sin 35

x = 9.177

How do i slove for x2 + 19 = 3

Answers

Answer:

x = ± 4i

Step-by-step explanation:

x^2 + 19 = 3

Subtract 19 from each side

x^2 +19-19 = 3-19

x^2 = -16

Take the square root of each side

sqrt(x^2) = sqrt(-16)

x = sqrt(-1*16)

x =sqrt(-1) * sqrt(16)

We know that the square root of -1 is the imaginary number i

x = ± 4i

It would double in size

Step-by-step explanation:

Judging as the circumference of a circle is dependent on the diameter, a circle whose diameter doubled in size would double.

An example would be a circle with the circumference of 20. It's radius would be 10 rather than 5. The circumference of the circle with a diameter of 10 would be roughly 31, while the circle with a diameter of 20 would have a circumference of roughly 62.

This means the numbers are being multiplied.

A number is being multiplied by the same number. You can write an exponent for the number of times it's being multiplied by itself.

Example:

x = x¹

x·x = x²

x·x·x = x³

You are multiplying (−6) twice.
