Answer:
13
Step-by-step explanation:
You need to use pythagorean theorem (a^2 + b^2 = c^2). In this case 5 is a, 12 is b, and z is c. 5^2 + 12^2 = z^2, this ends up as 169 = z^2. Now you find the square root of 169 which is 13.

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Nelson owes $950
Answer:
950, 1121.00, 1322.78, 1,560.88, 1,841.84
Step-by-step explanation:
Calculation to determine the sequences that describes his increasing monthly balance
Based on the information given in order for us to determine the sequence we have to multiply the amount owes by the interest rate and then add back the answer you got to the previous amount you multiplied the interest rate to.
First sequence will be the amount he owes on a credit which is $950
Second sequence
950 * .018 = 171.00
950 + 171.00 = 1121.00
Third sequence
1121.00 * .018 = 201.78
1121.00 + 201.78 = 1322.78
Fourth sequence
1322.78*0.18=238.10
1322.78+238.10=1,560.88
Last sequence
1,560.88*0.18=280.96
1,560.88+280.96=1,841.84
Therefore the sequences that describes his increasing monthly balance are:
950, 1121.00, 1322.78, 1,560.88, 1,841.84
Hey can you help me fast!!!
suppose the following system of equations has a solution of (9,-5)), where A, B,C, D, E, and F are real numbers
Ax + By =C
Dx + Ey =F
Which systems are also guaranteed to have a solution of (9,-5)? Select all that apply.
.......
Any system of equations that can be written in this form with real coefficients A, B, C, D, E, and F will have a solution of (9,-5).
What is a system of equation?If the system of equations has a solution of (9,-5), then we can substitute x = 9 and y = -5 into the equations and verify that they are true:
A(9) + B(-5) = C
D(9) + E(-5) = F
Simplifying these equations, we get:
9A - 5B = C
9D - 5E = F
So, any system of equations that can be written in this form will also have a solution of (9,-5):
9A - 5B = C
9D - 5E = F
Therefore, any system of equations that can be written in this form with real coefficients A, B, C, D, E, and F will have a solution of (9,-5).

How do you write an equation of a line given (1, 2) and (3, 4) in a slope -intercept form
Answer:
y = x + 1
Step-by-step explanation:
find slope first:
(4-2) / (3-1) = 2/2 or 1
now find the y-intercept, or 'b' by using one of the two given points and the slope
2 = 1(1) + b
2 = 1 + b
1 = b
equation in slope-intercept form:
y = 1x + 1 or y = x + 1

Prove algebraically that the square of any number is always 1 more than a multiple of 8
Answer:
This is interesting but I don't think it's provable (unless it's just the square of odd numbers).
3² = 9, which is 1 more than a multiple of 8 (8)
4² = 16, which is not 1 more than a multiple of 8 (8)
5² = 25, which is 1 more than a multiple of 8 (24)
6² = 36, which is not 1 more than a multiple of 8 (32)
7² = 49, which is 1 more than a multiple of 8 (48)
8² = 64, which is not 1 more than a multiple of 8 (64)
9² = 81, which is 1 more than a multiple of 8 (80)
10² = 100, which is not 1 more than a multiple of 8 (96)

The right rectangular prisms are similar. The bigger prism has a length of 2.2, width of .8, and height of 3.2. The smaller prism has a length of 1.1, width of .4, and height of 1.6.
Which statements are correct? Check all that apply.
- The angles in the smaller prism measure 90 degrees.
- The perimeter of the rectangular bases changes by a factor of 2.
- The surface area changes by a factor of 8.
- The larger prism has twice the volume of the smaller prism.
- The area of the rectangular bases changes by a factor of 4.
Answer:
The angles in the smaller prism measure 90 degrees.
The perimeter of the rectangular bases changes by a factor of 2.
The area of the rectangular bases changes by a factor of 4.
Step-by-step explanation:
Two polygons are said to be similar if they have the same shape and angles. Also, the ratio of their corresponding sides are to be in the same proportion.
A) Since the two prism are similar, therefore they are to have the same angle measure. The bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.
B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6
Perimeter of smaller prism base = 2(1.1 + 0.4) = 3
Hence, The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).
C) Surface area of bigger prism = 2(2.2*0.8 + 3.2*0.8 + 3.2*2.2) = 22.72
Surface area of smaller prism = 2(1.1*0.4 + 1.6*0.4 + 1.6*1.1) = 5.68
22.72 / 5.68 ≠ 8, hence the surface area does not change by a factor of 8
Option C is wrong
D) Volume of bigger prism = 3.2 * 2.2 * 0.8 = 5.632
Volume of smaller prism = 0.4 * 1.6 * 1.1 = 0.704
The volume of larger prism is not twice of the smaller prism (5.732 / 0.704 ≠ 2)
E) Area of bigger prism base = 2.2*0.8 = 1.76
Area of smaller prism base = 2.2*0.8 = 0.44
Since 1.76 / 0.44 = 4; The area of the rectangular bases changes by a factor of 4
A triangle has sides with lengths of 9 feet, 14 feet, and 15 feet. Is it a right triangle?
Answer:
No its not, because if you use the pythagorean theorem formula 9 and 14 will not equal 15. So it wouldn't make it a right triangle.

If cosec theta-cot theta is equal to 1/M then what is the value of cosec theta +cot theta
Given:
[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]
To find:
The value of [tex]\text{cosec}\theta +\cot \theta [/tex].
Solution:
We have,
[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]
We know that,
[tex]\text{cosec}^2\theta -\cot^2 \theta=1[/tex]
It can be written as:
[tex](\text{cosec}\theta -\cot \theta)(\text{cosec}\theta +\cot \theta)=1[/tex]
[tex]\dfrac{1}{M}\times (\text{cosec}\theta +\cot \theta)=1[/tex]
[tex]\text{cosec}\theta +\cot \theta=1\times M[/tex]
[tex]\text{cosec}\theta +\cot \theta=M[/tex]
Therefore, the value of [tex]\text{cosec}\theta +\cot \theta [/tex] is [tex]M[/tex].
