Second box: -5 x 0 + 1 = 1
Third box: -5 x 2 + 1 = -9
Fourth box: -5 x 4 + 1 = -19
Answer:
11, 1, -9, -19
Step-by-step explanation:
Use the equation to use x to solve for the Y's.
y = -5(-2) + 1
y = 11
put the 11 into the box in the Y column next to -2
solve for the next number, 0
y = -5(0) + 1
y = 1
for 2
y = -5(2) + 1
y = -9
For 4
y = -5(4) + 1
y = -19

The required angle is 24.5°.
Given is a right triangle with perpendicular side 16 and the base = 35 we need to find an acute angle in it,
To find the acute angle in a right triangle given the lengths of the perpendicular side and the base, you can use the tangent function.
The tangent of an angle is defined as the ratio of the length of the perpendicular side to the length of the base side.
In this case, the perpendicular side is 16 and the base is 35.
Let's denote the acute angle as θ.
Using the tangent function, we can set up the equation:
tan(θ) = perpendicular side / base
tan(θ) = 16 / 35
To find the value of θ, we can take the inverse tangent of both sides:
θ = tan⁻¹(16 / 35)
θ = 24.5°
Hence the required angle is 24.5°.

Answer the following word problem. A T-Rex skeleton has height of about. 12 ft., width of about 6 ft.,
and a length of about 40 ft. Can the museum director fit a fully built T-Rex skeleton display inside a
large case that is 5 yards high, 3 yards wide and 13 yards what is the case in feet?
Answers
Answer:
the fully built T-Rex skeleton display cannot fit inside the large case
Step-by-step explanation:
compare the dimensions of the skeleton to the dimensions of the case.
Given:
T-Rex skeleton dimensions:
Height = 12 ft.
Width = 6 ft.
Length = 40 ft.
Case dimensions:
Height = 5 yards
Width = 3 yards
Length = 13 yards
To compare the dimensions, we need to convert the case dimensions from yards to feet, as the T-Rex skeleton dimensions are given in feet.
1 yard = 3 feet
Case dimensions in feet:
Height = 5 yards * 3 feet/yard = 15 feet
Width = 3 yards * 3 feet/yard = 9 feet
Length = 13 yards * 3 feet/yard = 39 feet
Now we can compare the dimensions of the T-Rex skeleton and the case:
T-Rex skeleton:
Height = 12 ft.
Width = 6 ft.
Length = 40 ft.
Case:
Height = 15 ft.
Width = 9 ft.
Length = 39 ft.
Based on the dimensions, we can see that the height of the T-Rex skeleton (12 ft.) is smaller than the height of the case (15 ft.). Similarly, the width of the T-Rex skeleton (6 ft.) is smaller than the width of the case (9 ft.). However, the length of the T-Rex skeleton (40 ft.) is larger than the length of the case (39 ft.).
Therefore, the fully built T-Rex skeleton display cannot fit inside the large case because the length of the skeleton exceeds the length of the case.
C is the circumcenter of PQR
PC=3x+7, RC=5x-15 and QC=51-x.
what does RC equal?
Answers
Answer:
\( RC = 40 \)
Step-by-step explanation:
Given:
PC = 3x + 7,
RC = 5x - 15,
QC = 51 - x.
Required:
measure of RC
SOLUTION:
Given that C is the circumcenter of ∆PQR, therefore, vertices P, Q, and R are equidistant from C.
So therefore,
\( PC = RC = QC \)
Let's find the value of x using:
\( PC = RC \)
\( 3x + 7 = 5x - 15 \) (substitution)
Collect like terms
\( 3x - 5x = -7 - 15 \)
\( -2x = -22 \)
Divide both sides by -2
\( x = \frac{-22}{-2} \)
\( x = 11 \)
Find the measure of RC
\( RC = 5x - 15 \)
substitute x = 11 into the equation
\( RC = 5(11) - 15 \)
\( RC = 55 - 15 \)
\( RC = 40 \)

Domain & Range
The domain is the set of all possible input values (x-values).
The range is the set of all possible output values (y-values).
Question 5From inspection of the graph, the line is continuous.
The arrows either end of the line indicate that the line continues indefinitely in those directions.
Therefore, the domain of the relation is unrestricted: (-∞, ∞)
From inspection of the graph, the minimum y-value is y = -1.
The end behavior of the relation is:
\(y \rightarrow + \infty, \textsf{as } x \rightarrow - \infty\)
\(y \rightarrow + \infty, \textsf{as } x \rightarrow +\infty\)
Therefore, the range of the relation is restricted: [-1, ∞)
Question 6From inspection of the graph, the line is continuous.
The arrows either end of the line indicate that the line continues indefinitely in those directions.

Solve 2^x-2=8^4 but not solving for x
Answers
Without explicitly solving for x, we can conclude that the solution to the equation 2^x - 2 = 8^4 is x = 12.
To solve the equation 2^x - 2 = 8^4 without explicitly solving for x, we can simplify the equation using exponent rules and observe the relationship between the numbers.
First, let's simplify the equation:
2^x - 2 = 8^4
We know that 8 can be expressed as 2^3, so we can rewrite the equation as:
2^x - 2 = (2^3)^4
Applying the exponent rule (a^m)^n = a^(mn), we can simplify further:
2^x - 2 = 2^(34)
Simplifying the right side of the equation:
2^x - 2 = 2^12
Now, we can observe that both sides of the equation have the same base, which is 2. In order for the equation to hold true, the exponents must be equal:
x = 12
Therefore, we may deduce that the answer to the equation 2x - 2 = 84 is x = 12 without having to explicitly solve for x.

Step-by-step explanation:
You want the price with tax of a $35 pair of shoes subject to a 20% tax.
Price with taxThe tax is the cost of the shoes multiplied by the tax rate. The final price is the sum of the cost of the shoes and the tax:
final price = price + price × tax rate
final price = price × (1 + tax rate) = $35 × 1.20 = $42

Find a solution to the linear equation 13x + y = 26 by filling in the boxes with a valid value of x and y.
Answers
Answer:
MOM
Step-by-step explanation:
The solution to the equation are y = 26 - 13x and x = 2 - y/13
How to determine the solution?The equation is given as:
13x + y = 26
To do this, we solve for x and we solve for y
We have:
13x + y = 26
Subtract 13x from both sides
y = 26 - 13x
Also, we have:
13x + y = 26
Subtract y from both sides
13x = 26 - y
Divide through by 13
x = 2 - y/13
Hence, the solution to the equation are y = 26 - 13x and x = 2 - y/13

The correct matches are: 4 in. → 10.2 cm , 7 kg → 15.4 lb
6 gal → 22.7 L and 65 ft → 19.8 m.
What are conversions?Conversions refer to the process of changing a measurement from one unit to another unit that measures the same quantity.
For example, converting distance from miles to kilometers, or converting weight from pounds to kilograms.
Here are the conversions:
1 inch = 2.54 cm (approx.)
1 kg = 2.205 lb (approx.)
1 gal = 3.785 L (approx.)
1 ft = 0.3048 m (approx.)
Using these conversions, we can find the equivalent measures:
4 in. → 4 × 2.54 = 10.16 ≈ 10.2 cm
7 kg → 7 × 2.205 = 15.435 ≈ 15.4 lb
6 gal → 6 × 3.785 = 22.71 ≈ 22.7 L

Ciana should purchase the skirt at the store across town because the total economic cost will be lowest.
How to determine the opportunity cost?Ciana makes $30 per hour at her work, and her purchase decision includes the opportunity cost of lost wages:
Total economic cost:
Local store = $114 + [1/4 hours x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $144
Across town = $86 + [1/2 hours x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $131
Neighboring city = $60 + [1 hour x 2 (round trip) x $30] + (1/2 hours x $30 spent shopping) = $135
Ciana should buy a skirt at the store across town. Because it has the lowest total economic cost ($131).
