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°
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.
[tex]V=\dfrac{d_1+d_2+d_3+d_4}{t_1+t_2+t_3+t_4}[/tex]
Since, distance = velocity × time
Also, 1 hour = 60 min
[tex]V=\dfrac{v_1t_1+v_2t_2+v_3t_3+v_4t_4}{t_1+t_2+t_3+t_4}\\\\V=\dfrac{95\times \dfrac{60}{60}+55\times \dfrac{10}{60}+45\times \dfrac{35}{60}+0\times 50}{\dfrac{60}{60}+\dfrac{10}{60}+\dfrac{35}{60}+\dfrac{50}{60}}\\\\V=50.48\ \text{km/h}[/tex]
The average speed for the trip is 50.48 km/h
(b) Total distance,
[tex]D=v_1t_1+v_2t_2+v_3t_3+v_4t_4\\\\D=95\times \dfrac{60}{60}+55\times \dfrac{10}{60}+45\times \dfrac{35}{60}+0\times 50\\\\D=130.41\ \text{km}[/tex]
The distance between the initial and final cities along the route is 130.41 km.

simplify the ratio
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:
[tex]\displaystyle \frac{10}{17}[/tex]
Since the denominator is a prime number, no more simplifying is possible, thus the given ratio is equivalent to:
[tex]\boxed{\displaystyle \frac{10}{17}}[/tex]

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°

In the following diagram, it is known that EHG is a right angle, m EHF x 1 and m GHF x 5 5.
Find the value of x, the numerical values of m EHF m GHF and , and mark them on the diagram
Answer:
Step-by-step explanation:
From the diagram, it can be seen that m EHF+ m GHF = mEHG
mEHG is a right angle, then mEHG = 90°
Given
m EHF = x
m GHF = 5x
Substituting the given parameters into the formula to get x;
x+5x= 90
6x = 90
Divide both sides by 6;
6x/6 = 90/6
x = 15
Hence the value of x is 15°
Since m EHF = x, therefore the numerical value of m EHF is 15°.
Also since m GHF = 5x, the numerical value of m GHF = 5(15) = 75°

11. The first four terms of an AP, whose first term is -2 and common difference is -2 are
Answer:
- 2, - 4, - 6, -8
Step-by-step explanation:
If the first term of the arithmetic sequence is is -2 , and the common difference is -2, then we can generate the first four terms the following way:
a1 = - 2
a2 = - 2 - 2 = - 4
a3 = - 4 - 2 = - 6
a4 = - 6 - 2 = - 8

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
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
