Find the measure of angle ADE
Answer:
17x + 22
Step-by-step explanation:
They are supplementary angles...
Which means...
Angle ADE = (4x+15) + (13x+7)
= 17x + 22
So...
Angle ADE = 17x + 22

A deposit that is compounded semiannually at 8% for 4 years has a table value of 0.73503 true or false
Answer:
FALSE
Step-by-step explanation:
This answer is false. The interest rate per period is 4% (8% / 2), and the total number of compounding periods is 8 (4 years x 2 periods per year).
Therefore, find the intersection of 4% and 8, which is 0.73069.

Jeremy is trying to explain why a triangle with side lengths 35, 30, 60 is not a right triangle. His explanation is shown below.
Step 1: 35 squared + 30 squared question mark equals 60 squared
Step 2: (35 + 30) squared question mark equals 60 squared
Step 3: 65 squared question mark equals 60 squared
Step 4: 4,225 not-equals 3,600
Which best describes Jeremy’s explanation?
Jeremy’s explanation is accurate.
Jeremy’s explanation is inaccurate. He wrote the leg lengths in the incorrect order in step 1.
Jeremy’s explanation is inaccurate. He incorrectly combined terms in step 2.
Jeremy’s explanation is inaccurate. He multiplied incorrectly in step 4.
Answer:
i would say a is the correct answer
Answer:
He incorrectly combined terms in step 2
Step-by-step explanation:
In Step 2, you can't combine 30² + 35² into (30 + 35)² so the answer is "He incorrectly combined terms in step 2".

x-1=y what is the answer plz give me the answer
Answer:
X = 0Y = 1First of all, observe that this is a line, since you can rewrite the equation as y−x+1=0 , which follows the pattern of the generic line ax+by+c=0 .
To draw a line you need two of its points, which you can connect.
To find two points, you can plug any value for one variable, and solve for the other.
For example, let's choose
x=0 . The equation becomes
0−1=y , and so y=−1 .
The first point is thus (0,−1).
Then, let's choose
x=1 . The equation becomes 1−1=y , and so y=0 . The first point is thus
(1,0).
Now you only need to draw the points
(0,−1)

Which rule describes the composition of transformations that maps ΔABC to ΔA"B'C"?
Answer:
The Answer is A or the first one, NOT C. C is wrong.
Step-by-step explanation:
The transformations that map ΔABC to ΔA"B"C" will be reflection cross x-axis and translation of (x - 6, y - 2). Then the correct option is B.
What is a transformation of a shape?A point, line, or numerical figure can be changed over in one of four ways, and each affects the item's design as well as position. Picture, after interpretation, alludes to the article's definitive association and situation. Not long before the alludes to the material's underlying condition.
The interpretation doesn't change the shape and size of the calculation. However, changes the area.
The reflection doesn't change the shape and size of the math. However, flipped the picture.
The changes that map ΔABC to ΔA"B"C" will be reflection cross x-pivot and interpretation of (x - 6, y - 2). Then, at that point, the right choice is B.

Answer:
y = n^2 +nupper left corresponds to n^2; lower right corresponds to nStep-by-step explanation:
The number of squares in the upper left portion of the figure is the number in a square n on a side, so is n^2. The number of squares in the lower right portion of the figure is equal to the step number, n. A suitable equation adds these numbers together.
y = n^2 +n . . . . where y is the number of squares in the pattern of Step n.

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Answer:
The equation is given by:
[tex]D(t) = 80 + 9\sin{0.2618t}[/tex]
Step-by-step explanation:
Sine function:
Has the following format:
[tex]y = A\sin{bx}[/tex]
In which A is the amplitude and [tex]\frac{2\pi}{b}[/tex] is the period.
Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees
This means that the amplitude of the sinusoidal variation function is 89 - 80 = 80 - 71 = 9. This means that [tex]A = 9[/tex]
During a 24-hour day, which means that the period is 24. So
[tex]\frac{2\pi}{b} = 24[/tex]
[tex]24b = 2\pi[/tex]
[tex]b = \frac{2\pi}{24}[/tex]
[tex]b = 0.2618[/tex]
So the variation is:
[tex]V(t) = 9\sin{0.2618t}[/tex]
Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Initial temperature of 80, so:
[tex]D(t) = 80 + V(t) = 80 + 9\sin{0.2618t}[/tex]
