Answer:
(-1, 0)
Step-by-step explanation:
output = 0 the function’s graph will have an x-intercept
The solution is : (-1, 0), (2, 0), (3, 0) are the x-intercepts of the continuous function f(x).
What are x-intercepts of quadratic function?The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
here, we have,
we know that,
x-intercept of a line is defined by a point where y = 0.
So the point in the form of (x, 0) will be the x-intercept of the given continuous function.
From the table attached,
For x = -1, f(-1) = 0
For x = 2, f(2) = 0
For x = 3, f(3) = 0
Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the continuous function f(x).

Action figures are $8 a piece at a toy store. The toy store sold 26 action figures today. How much money did the toy store receive from selling action figures today?
The toy store received $208 from selling action figures.
Knowing that each action figure is $8 in the toy store, we can multiply that by the quantity of action figures sold to get the total amount of money received.
26 times $8 is $208.
Answer:
$208
Step-by-step explanation:
If the toys are $8 a peice and they sold 24 toys then they would recive $208. Think of it this way: if you multiply 8 times 2 you get 16, then you multiply 16 by 10 to represent 20 of the action figures. That would get you $160. Then multiply 8 times 6, and that gets you 48. Now add those two together. 160+48=$208
Find the values of x and y
Answer:
x = 29.44
y = 34
Step-by-step explanation:
For this problem, we will simply use trigonometry to find the values of y and x for the given triangle.
The two trigonometric functions we will use are tangent and sine.
The general form for tangent is:
tan (Θ) = opposite / adjacent
The general form for sine is:
sin (Θ) = opposite / hypotenuse
For our given triangle, let's solve for x.
tan (30) = 17 / x
x * tan(30) = (17 / x) * x
x tan(30) = 17
x tan(30) * ( 1 / tan(30) ) = 17 * ( 1 / tan(30) )
x = 17 / tan(30)
x = 29.44
Now, let's solve for y.
sin (30) = 17 / y
y * sin(30) = (17 / y ) * y
y sin (30) = 17
y sin (30) * ( 1 / sin(30) ) = 17 * ( 1 / sin(30) )
y = 17 / sin(30)
y = 34
Hence, the values of x and y in our triangle are as follows:
x = 29.44
y = 34

Identify the initial value, a, and base, b, of the function f(x)=ab^x if its graph passes through the points (0, 4) and (1, 20)
Answer:
a = 4, b = 5
Step-by-step explanation:
Given the exponential function
f(x) = a[tex]b^{x}[/tex]
Use the given points to find a and b
Using (0, 4 ) , then
4 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , thus
a = 4 , so
f(x) = 4[tex]b^{x}[/tex]
Using (1, 20 ) , then
20 = 4b ( divide both sides by 4 )
b = 5

what is the distance between -4 and 8 on a number line
Answer:
12
Step-by-step explanation:
you can hop 12 times to the right
The distance between -4 and 8 on a number line is 12.
To find the distance between -4 and 8 on a number line, you can subtract the smaller number from the larger number. In this case:
Distance = |8 - (-4)|
To subtract a negative number, you can think of it as adding the absolute value of that negative number:
Distance = |8 + 4|
Now, perform the addition:
Distance = |12|
The absolute value of 12 is 12, so the distance between -4 and 8 on a number line is 12 units.
Hence, the distance between -4 and 8 on a number line is 12.

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 60.0 min at 95.0 km/h, 10.0 min at 55.0 km/h, and 35.0 min at 45.0 km/h and spends 50.0 min eating lunch and buying gas.
(a) Determine the average speed for the trip. km/h
(b) Determine the distance between the initial and final cities along the route. km
Step-by-step explanation:
(a) The average speed of a person for the trip is given by total distance traveled divided by total time taken.

Shanice wanted to make note cards by
cutting pieces of paper in half. Before
starting she got two more pieces to use.
When she was done she had 20 half-pieces
of paper. With how many pieces did she
start?
Answer:
8 pieces of paper
Step-by-step explanation:
Since the paper was cut into two, divide the half-pieces by 2 go get the amount of full-sized paper. And since Shanie got 2 more pieces of paper before she started, you subtract 2 from 10, which leaves you with 8 pieces of full-sized paper.

2km: 3400m
Answer:
[tex]\displaystyle \frac{10}{17}[/tex]
Step-by-step explanation:
Fraction Simplifying
We are given the ratio 2 Km:3400 m. This can be written in fraction form as:
[tex]\displaystyle \frac{2\ km}{3400\ m}[/tex]
Since 2 Km = 2000 m:
[tex]\displaystyle \frac{2\ km}{3400\ m}=\frac{2000\ \not{m}}{3400\ \not{m}}[/tex]
We need to simplify the fraction:
[tex]\displaystyle \frac{2000}{3400}[/tex]
We cancel out two zeroes, which is like dividing both numbers by 100:
[tex]\displaystyle \frac{20\not{0}\not{0}}{34\not{0}\not{0}}[/tex]
The remaining fraction is:
[tex]\displaystyle \frac{20}{34}[/tex]
Dividing both by 2:

A. cos B
B. cos(90° - A)
C. sin(90°- B)
D. Both A and B
2. The maximum slope for a hand propelled wheel chair ramp should be a 1-inch rise to every 12 inch of length. What is that maximum ramp angle recommended to the nearest degree?
Answer:
1) B
2) About 5°.
Step-by-step explanation:
1)
We can use the following co-function identity:
[tex]\sin(\theta)=\cos(90-\theta)[/tex]
Substitute A for θ:
[tex]\sin(A)=\cos(90-A)[/tex]
Since we know that sin(A) is 1/3, this means that cos(90-A) must also be 1/3.
So, our answer is B.
2)
Refer to the drawing.
Remember that 1-inch rise is a height of 1 while a 12 inch length is a length of 12.
So, to find the maximum ramp angle, we simply need to find the value of x.
We know the sides opposite and adjacent to x. So, we can use tangent:
[tex]\tan(x)=\text{opp}/\text{adj}[/tex]
Substitute 1 for the opposite side and 12 for the adjacent side:
[tex]\tan(x)=1/12[/tex]
Take the inverse tangent of both sides:
[tex]x=\tan^{-1}(1/12)[/tex]
Use a calculator. Make sure you're in Degrees mode:
[tex]x\approx4.76\textdegree\approx5\textdegree[/tex]
So, the maximum ramp angle should be about 5°

Put the following equation of a line into slop-intercept form, simplifying all fractions.
2y - x = -8
Answer:
y = x/2 - 4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Write equation
2y - x = -8
Step 2: Solve for y
Add x to both sides: 2y = x - 8
Divide both sides by 2: y = x/2 - 4
If m∠2=40°, what is the measure of ∠1 + ∠6?
Answer:
180°
Step-by-step explanation:
The diagram for this question has been attached to this response.
From the diagram;
(i) ∠2 and ∠6 are equal since they are corresponding angles. This implies that the measure of angle 2 (m∠2) is equal to the measure of angle 6 (m∠6). i.e
m∠2 = m∠6 ---------(a)
But m∠2 = 40°
Substitute this into equation (a) as follows;
40° = m∠6
∴ m∠6 = 40°
(ii) ∠1 and ∠2 are supplementary. This implies that the sum of the measures of angle 1 (m∠1) and angle 2(m∠2) is equal to 180°. i.e
m∠1 + m∠2 = 180° ------------------(b)
But m∠2 = 40°
Substitute this into equation (b) as follows;
m∠1 + 40° = 180°
m∠1 = 180° - 40°
m∠1 = 140°
(iii) The measure of ∠1 + ∠6 is given by;
m∠1 + m∠6
Substitute the values of m∠1 = 140° and m∠6 = 40° into the expression to get
m∠1 + m∠6 = 140° + 40°
m∠1 + m∠6 = 180°
Therefore the measure of ∠1 + ∠6 is 180°
