the base and exponent of (3.5)^5
with explain
Step-by-step explanation:
The base is 3.5 because it is the one being multiplied to itself for 5 times.
5 is the exponent because it tells us that we have to multiply 3.5 to itself 5 times.

Answer:
Input is the number in the first column of the table. This is the number that you start with to follow the rule if the rule is given. You would also use this number to figure out what the rule is if it is not given.
Step-by-step explanation:
An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (\begin{align*}x\end{align*}-value) by 3 to find each output number (\begin{align*}y\end{align*}-value).
The school that Adam goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 5 senior citizen tickets and 15 student tickets for a total of $137.50. The school took in $430 on the second day by selling 20 senior citizen tickets and 44 student tickets. Find the price of a student ticket.
Answer:
Let the price of one senior citizen ticket be sc and the price of one student ticket be st.
Let's write equations using the information given and the variables above:
=> 5sc + 15st = $137.50
=> 20sc + 44st = $430
Hmm.. We can multiply 5sc by 4 to get 20sc.
=> 4(5sc) + 4(15st) = 4($137.50)
=> 20sc + 60st = $550
Now we can subtract the second equation from the first to determine the price of a student ticket.
20sc + 60st = $550
- 20sc + 44st = $430
=> 16st = $120
=> st = $7.5
So, the price of a student ticket is $7.5.

What is the gradient of the blue line?
Answer:
gradient is 0.35
Step-by-step explanation:
The gradient or slope of the line is 1/4.
What is the slope of a line?The slope of a line indicates the direction and the steepness of the line. The formula for the slope of a line passing through the points (x₁,y₁) and (x₂, y₂) is m = (y₂-y₁)/(x₂-x₁).
The graph of the line is given.
Note that the line passes through the point (0,1) ad (4,2).
The gradient of the line is nothing but the slope of the line.
The slope of the line is:
m = (2-1)/(4-0)
m = 1/4
Hence, the gradient or slope of the line is 1/4.

OK THIS IS MY LAST QUESTION PLS HELP I NEED TO GET THIS CORRECT
Answer: Quad IV
Step-by-step explanation:
Can u help me please
slope = -2
y intercept = 6
=====================================================
Explanation:
Let's find the slope
m = (y2-y1)/(x2-x1)
m = (2-4)/(2-1)
m = -2/1
m = -2
The slope is -2
Let's use this slope along with the first point to get the y intercept
y = mx+b
y = -2x+b ... plug in the slope we found earlier
4 = -2*1+b ... plug in the coordinates of the point (1,4)
4 = -2+b
4+2 = -2+b+2 .... adding 2 to both sides
6 = b
b = 6
The y intercept is 6
The equation y = mx+b turns into y = -2x+6 since m = -2 is the slope and b = 6 is the y intercept.
Find the Derivative.
f(x) = -xcos3x
Answer:
[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]
Step-by-step explanation:
Use the Product Rule for derivatives, which states that:
[tex]\frac{d}{dx} =[f(x)g(x)]= f(x)g'(x)+f'(x)g(x)[/tex]In the function we are given, [tex]f(x)=-x \cos3x[/tex], we can break it up into two factors: -x is being multiplied by cos3x.
Now, we have the factors:
[tex]-x \\ $cos 3x[/tex]Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.
[tex]\frac{d}{dx}(cos3x)= \frac{d}{dx} (cos3x) \times \frac{d}{dx} (3x) \\ \frac{d}{dx}(cos3x)= (-sin3x) \times 3 \\ \frac{d}{dx} (cos3x) = -3sin(3x)[/tex]Now let's apply the product rule to f(x) = -xcos3x.
[tex]\frac{d}{dx}(-xcos3x)= (-x)(-3sin3x) + (-1)(cos3x)[/tex]Simplify this equation.
[tex]\frac{d}{dx}(-xcos3x)= (x)(3sin3x) - (cos3x)[/tex]Multiply x and 3 together and remove the parentheses.
[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]Therefore, this is the derivative of the function [tex]f(x)=-xcos3x[/tex].
Hi there!
[tex]\large\boxed{f'(x) = -cos3x + 3xsin3x}[/tex]
[tex]f(x) = -xcox3x\\\\\text{Use the product rule and chain rule to solve for the derivative:}\\\\\frac{dy}{dx}= -cos3x + (-x * (-sin3x) * 3)\\\\= -cos3x + 3xsin3x[/tex]

Answer:
Step-by-step explanation:
4) ΔSTW ≅ ΔBFN . So, corresponding parts of congruent triangles are congruent.
a) BN = SW d) m∠W = m∠N
BN = 9 cm m∠W = 82°
b) TW = FN e) m∠B = m∠S
TW = 14 cm m∠B = 67°
c) BF = ST f) m∠B + m∠N + m∠F = 180°
BF = 17 cm 67 + 82 + m∠F = 180
149 + m∠F = 180
m∠F = 180 - 149
m∠F = 31°
5) ΔUVW ≅ ΔTSR
UV = TS
12x - 7 = 53
12x = 53+7

3z +14 = 50
3z = 50 - 14
3z = 36
z = 36/3
z = 12
SR =VW
5y - 33 = 57
5y = 57 + 33
5y = 90
y = 90/5
y = 18
7) ΔPHS ≅ ΔCNF
∠C = ∠P
4z - 32 = 36
4z = 36 + 32
4z = 68
z = 68/4
z = 17
∠H = ∠N
6x - 29 = 115
6x = 115 + 29
6x = 144
x = 144/6
x = 24
∠P + ∠H + ∠S = 180 {Angle sum property of triangle}
36 +115 + ∠S = 180
151 + ∠S = 180
∠S = 180 - 151
∠S = 29°
∠F = ∠S
3y - 1 = 29
3y = 29 + 1
3y = 30
y = 30/3
y = 10
8) ΔDEF ≅ ΔJKL
DE = 18 ; EF = 23
DF = 9x - 23
JL= 7x- 11
DF = JL {Corresponding parts of congruent triangles}
9x - 23 = 7x - 11
9x - 7x - 23 = -11
2x - 23 = -11
2x = -11 + 23
2x = 12
x = 12/2
x = 6
JK = DE {Corresponding parts of congruent triangles}

The Grand Canyon Skywalk at Eagle Point is a horseshoe shaped steel frame with a glass floor looking down to the Grand Canyon below. The Skywalk extends 70 feet over the canyon rim and is 10 feet wide. The walkway consists of a semicircle with a straight portion on each side as indicated in the diagram below. How many square feet of glass are needed to cover the Skywalk floor? (Round your final answer to 1 decimal place and any intermediate calculations to 2 decimal places. Be sure to include units.)
Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.
Step-by-step explanation: The figure below shows the area in question.
Area of a circle is given by
[tex]A=\pi.r^{2}[/tex]
The walkway is a semicircle. Then, area will be:
[tex]A=\frac{\pi.r^{2}}{2}[/tex]
The area that will be covered with glass is the area between the outer and the inner circles. So, area is
[tex]A_{t}=A_{outer}-A_{inner}[/tex]
[tex]A_{t}=\frac{\pi.r_{o}^{2}}{2}- \frac{\pi.r_{i}^{2}}{2}[/tex]
[tex]A_{t}=\frac{\pi}{2}(32.5^{2}-22.5^{2})[/tex]
[tex]A_{t}=\frac{\pi}{2}(550)[/tex]
[tex]A_{t}=[/tex] 864
To cover the Skywalk floor is needed 864[tex]ft^{2}[/tex] of glass.
