How do i slove for x2 + 19 = 3
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
Mr. Romero buys 3 chairs at a cost of $27.90 for each chait. Estimate the

write the product using exponents
(−6)⋅(−6)
Answer:
-6^2
Step-by-step explanation:
-6 x -6 = 36
Answer:
(−6)²
Step-by-step explanation:
(−6)⋅(−6)
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.
(−6)⋅(−6) = (−6)²
Find the length of CB round to the nearest tenth.
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
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:
1/4

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

Answer:
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.

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

Find two numbers whose sum is 8 and whose product is 17. Show all steps.
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
Anyone knows the answer pls ????
