$750 at a 4% annual compound interest rate over a period 4 years
Which of the following statements are true of the data? Check all that apply.
The starting balance of the 3rd year is $811.20.
The interest earned in the 3rd year is $31.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.
The ending balance for the 4th year is $874.85.
Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.
Step-by-step explanation:
750 × (1 + 4%)^n
750 × (1.04)^n
750 × 1.04² = 811.2
(End of second year, starting of third year)
750 × 1.04³ = 843.648
In third year: 843.648 - 811.2
= 32.448
750 × 1.04⁴ = 877.39392
During the fourth year:
877.39392 - 843.648
33.74592
Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.

Which of the following points on the xy-graph is the x-intercept of the equation y= 2x– 8? Hint: plug in first value for x, do order of operations until you get the 2nd value in the coordinate)
Answer:
Step-by-step explanation:
The x-intercept of the equation y = 2x – 8 will be 4.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given below.
y = 2x– 8
Form the x-intercept, substitute the value of y equals zero. Then we have
0 = 2x– 8
2x = 8
x = 4
The x-intercept of the equation y = 2x – 8 will be 4.

Question in image. Thanks!
Answer:
B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)
Step-by-step explanation:
If all angles that are either adjacent or opposite are supplementary, all angles must be 90°
If at all times adjacent sides are 5 inches, all sides are equal.
Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

Mya's lunchbox is shown. What is the volume of the lunchbox? Round to the nearest tenth if necessary.
The volume of Mya's lunchbox can be calculated by multiplying its length, width, and height. However, the dimensions were not provided in the question.
Explanation:The volume of a three-dimensional object like Mya's lunchbox can be found by multiplying the object's length, width, and height together. If Mya's lunchbox is a rectangular prism, for instance, and we know its measurements, we can calculate its volume using the formula Volume = Length x Width x Height. However, the question didn't provide the necessary dimensions of the lunchbox. Therefore, you need to provide the dimensions of the lunchbox for me to be able to help you calculate its volume.

Answer:
x = -4
Step-by-step explanation:
Square both sides:
[tex](\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2[/tex]
The square root and the square will cancel to leave simply the argument within the square root:
-5 - 2x = -1 - x
Now simply isolate the variable x:
x = -5 + 1 = -4
Check to see if x = -4 will work:
[tex]\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}[/tex]
[tex]\sqrt{3} =\sqrt{3}[/tex]
This works, so we know that x = -4 is a solution.
