Consider the equation: x^2+10x+22=13
Need help asap!!!!
this is due in a hour!
Answers
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2

Answer:
[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]
Step-by-step explanation:
Given
[tex]\frac{4}{3 - i}[/tex]
See attachment for question
Required
Correct Ramon's error
Start by rationalizing the expression:
[tex]\frac{4}{3 - i} = \frac{4}{3 - i}*\frac{3 + i}{3 + i}[/tex]
[tex]\frac{4}{3 - i} = \frac{4(3 + i)}{(3 - i)(3 + i)}[/tex]
Expand
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{3^2 - i^2}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - i^2}[/tex]
In complex numbers:
[tex]i^2 = -1[/tex]
So:
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - (-1)}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 +1}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{10}[/tex]
Split fraction
[tex]\frac{4}{3 - i} = \frac{12}{10} + \frac{4i}{10}[/tex]
[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

Write an equation of the line that passes through the given point and is parallel to the given line.
(2, -3); y = –5
Answers
Answer:
y = -3
Step-by-step explanation:
The given line is a horizontal line thru -5 on the y-axis.
Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3). Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.

Find the area of triangle ABC.
Give your answer correct to 1 decimal place.
А
9 cm
C
10 cm
B

Answers
The area of the triangle ABC is 34.2 square centimeters
How to determine the triangle area?The complete question is in the image
Start by calculating the semi-perimeter using:
s = 0.5 * (a + b + c)
This gives
s = 0.5 * (9 + 10 + 8)
Evaluate
s = 13.5
The area is then calculated as:
[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]
This gives
[tex]A = \sqrt{13.5 * (13.5 - 9) * (13.5 - 10) * (13.5 - 8)[/tex]
Evaluate
A = 34.2
Hence, the area of the triangle ABC is 34.2 square centimeters

You put $800 into an investment at 7% for three years. What will the balance be at the end of three
years?
Answers
Answer:
$980.03
Step-by-step explanation:
$800 x 0.07 = $56
($800 + $56) x 0.07 = $59.92

$856 + $59.92 + $64.11 = $980.03

What is the diagonal length of the table top?
O A 127

Answers
a squared + b squared = c squared for the sides and hypotenuse of the triangle.
6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
c = square root of 72, 8.49
.A 15 m ladder rests against a wall at an angle of 60° with the ground. How far is the
foot of the ladde from the wall?
Answers
9514 1404 393
Answer:
7.5 m
Step-by-step explanation:
The cosine relation applies.
Cos = Adjacent/Hypotenuse
cos(60°) = (distance to wall)/(15 m)
distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m
The foot of the ladder is 7.5 m from the wall.
how do I solve this?
Answers
9514 1404 393
Answer:
x ≈ 24.91
Step-by-step explanation:
It is helpful to remember the mnemonic SOH CAH TOA. It is intended to remind you that ...
Sin = Opposite/Hypotenuse
You observe that the values are given in the figure for an acute angle in a right triangle, the hypotenuse, and the side opposite the angle. That is why you are interested in the sine relation.
sin(49°) = x/33
x = 33·sin(49°) ≈ 24.905
The length of side x is about 24.91 units.

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.
Answers
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
Step-by-step explanation:
I (interest) =P (principal) x R (rate) x T (time)
I=3500x.09x150/365
I=129.45
A (amount due) = P (principal) + I (interest)
A= 3500 + 129.45
A= $3629.45

Step-by-step explanation:
1. I don't know how to solve that sorry :(
-----------------------------------------------------------
2. B. It is a diameter
------------------------------------
3. All triangles = 180°
180° = 60° + 90° + q
180° = 150° + q
180° - 150° = 150° - 150° + q
30° = q
180° = 60° + 90° + 30°
180° = 150° + 30°
180° = 180°

4. I don't know sorry :(

Answers
Answer:
x = 22 degrees
Step-by-step explanation:
Since this is a right angle and both angles added together will equal to 90degrees this means that:
(3x-5) + (x+7) = 90
(first, remove the brackets)
3x-5+x+7 = 90
( add the numbers together and the term x together)
( 3x+x ) + ( -5+7 ) = 90
4x + 2 = 90
(subtract 2 from both sides)
4x = 88
(divide by 4 from both sides)
x = 22
so the measure of x = 22 degrees
