A. 11.6
B. 13
C. 16.6
D. 22.4
Answer:
B
Step-by-step explanation:
The perpendicular is sin(43)*39=21.82. Next tan(32)=x/21.82. x=21.82*tan(32)=13.6
The value of x in the given question is 16.6
What are trigonometric ratios in a right angle triangle ?A right angle triangle has 3 sides opposite is the side opposite to the angle formed by two adjacent sides.hypotenuse is the largest side and adjacent is the remaining side.
Assuming height of the triangle = y
Sin∅ = opposite/hypotenuse
sin43° = y/39
y= 39sin43°
y = 26.6
From this we will solve the value of x
tan∅ = opposite/adjacent
here adjacent = 26.6 and opposite = x
tan32° = x/26.6
x = 26.6tan32°
x = 16.6

Find an equation for the line below.
BRAINLIEST AND POINTS!
Answer:
y = 4/3x+2/3
Step-by-step explanation:
the 2 coordinates provided are: (4,6) and (-5,-6)
y=mx+c
m= (y1-y2)/(x1-x2) = (-6-6)/(-5-4) = 4/3
sub x = 4, y = 6
6 = 4/3 * 4 + c
c = 2/3
Answer:
y = 4/3x+2/3
Step-by-step explanation:
Pick two points on the line to find the slope
(-5,-6) and (4,6)
m = (y2-y1)/(x2-x1)
m = ( 6 - -6)/( 4 - -5)
= ( 6+6)/(4+5)
= 12/9
= 4/3
The slope intercept form of a line is y =mx+b where m is the slope and b is the y intercept
y = 4/3x+b
Substitute a point into the equation
6 = 4/3(4)+b
6 = 16/3+b
Subtract 16/3 from each side
18/3 - 16/3 =b
2/3 = b
y = 4/3x+2/3
Amy is biking to school from her father's house and Jeremy is biking to school from his aunt's house. Suppose Amy is moving at a rate 10 miles per hour and Jeremy is moving at a rate of 8 miles per hour. Can you assume that Amy will get to school first?
Answer:
No, more information is needed to prove that Amy will get to school first.
Step-by-step explanation:
Even though Amy is traveling at a faster rate than Jeremy, the problem does not say how far away Amy's father's or Jeremy's aunt's houses are from the school.
Answer:
Step-by-step explanation:
No, the rate with the greater positive rate of change will not necessarily reach the output with the smallest input. The initial value will also affect the outcome. Although Amy is biking at a faster rate of change, Jeremy might get to school before her if his aunt lives closer to the school than her father does.

A. quadratic; y = 2.5x2
B. exponential; y = 2.5x
C. quadratic; y = –2.5x2
D. linear; y = 2.5x
Answer:
A. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
x -2 -1 0 1 2
y 10 2.5 0 2.5 3.0
Ist difference,
= -2.5
= 2.5
= 7.5
2nd difference,
= 5
= 5
= 5
Since 2nd difference is common, given table represents a quadratic equation.
Let the equation is,
y = ax²+ bx + c
For a point (0, 0) passing through the quadratic equation,
0 = c
Therefore, quadratic equation is y = ax² + bx
Since ordered pair (-1, 2.5) passes through the graph of the function,
2.5 = a(-1)² + b(-1)
a - b = 2.5 ------(1)
For another point (1, 2.5)
2.5 = a(1)² + b(1)
a + b = 2.5 ------(2)
By adding equations (1) and (2),
2a = 5
a = 2.5
and from equation (2)→ y = 0
Therefore, equation of the quadratic function given in the table is y = 2.5x²
Option (1) is the answer.

The foot of a ladder is placed 18 feet from a wall. If the top of the ladder rests 24 feet up on the wall, find the length of the ladder.
Answer:
30 ft
Step-by-step explanation:
Because the wall and floor form a right angle, then
a**2 + b**2 = c**2
18**2 + 24**2 = c**2
324 + 576 = c**2
900 = c**2
30 = c

A ramp is used to load a snowmobile onto the back of a pickup truck. The truck bed is 1.3m above the ground. For safety, the angle of the ramp should be less than 40°. What is the shortest possible length of the ramp to the nearest centimetre? Explain why.
Answer:
2.02 m
or 2 m 2 cm
Step-by-step explanation:
Imagine a triangle containing the 40° angle and that this angle is at the left. Then the height of the truck bed is 1.3 m and the "shortest possible length of the ramp" is the hypotenuse of this triangle. We need to find the length of this ramp, that is, the length of the hypotenuse.
The sine function relates this 40° angle and the 1.3 m height of the truck bed:
sin 40° = opp / hyp = 1.3 m / hyp
which can be solved for 'hyp' as follows:
1.3 m
hyp = ----------------- = (1.3 m) / 0.6428)
sin 40°
1.3 m
Thus, the length of the ramp must be less than -------------- or 2.02 m
0.6428
where this last result is to the nearest cm.
If the ramp is shorter the angle of the ramp will be smaller and the ramp angle considered safer.

NOT be orange?
'h. If a pencil is picked at random, what is the probability that the pencil will
NOT be blue or red?
Answer:
Step-by-step explanation:
F. 5/7 chance
G. 9/14 chance
H. You did not mention a blue color in the question.
Answer:
g) a) 11/14
f) 9/14
h) 12/14
Step-by-step explanation:
Probability is just the amount of the specified object over the total amount of objects.
Amount of Red : 2
Amount of Orange: 5
Amount of Green: 3
Amount of Brown: 4
Total: 14
*Formula: (Specified Object)/(Total)*
F) Chances of Red or Orange or Green
=(2+5+4)/14
=11/14
G) NOT be orange
*Formula: (Total)-(Specified)/(Total)*
=(14-5)/14
=9/14
H) NOT blue or red
*Formula: (Total)-(Specified)/(Total)*
=14-(2+0) (*There is a 0 there because the question asked to solve for blue pencils as well, and there are 0 blue pencils*)
= 12/14
It takes Jacob 25 minutes to line 2/3 of the flag football field. At this rate, how long will it take to line the entire field. *
Answer:
12.5 minutes
Step-by-step explanation:
Just divide 25 by 3 to get 12.5
Answer:
37.5 minutes
Step-by-step explanation:
We can set a ratio to model this problem
It takes Jacob 25 minutes to line 2/3 of the flag football field.
The ratio here is 25 : 2/3.
We want to figure out what x : 1 is.
25 : 2/3
x : 1
We can model this by fractions:
[tex]\frac{25}{\frac{2}{3}} = x[/tex]
When you divide by a fraction, you end up multiplying it by the reciprocal.
[tex]25(\frac{3}{2})=x[/tex]
[tex]x=\frac{75}{2}[/tex]
[tex]x = 37.5[/tex]

let's just assume the values of x to be 0,1,2and3
so when x= 0
using the given formula y=2x-3
we get
y= 2(0)-3
=0-3
= -3
so we have x=0,y=-3
we do the same for the rest of the values
y=2(1)-3=2-3 =-1
y=2(2)-3=4-3= 1

Answer:

Step-by-step explanation:
A staircase is being constructed in a new house as displayed on the right. Each tread is 18 cm and each riser is 10cm. Determine the angle of inclination of the stairs.
Answer:
29.1°
Step-by-step explanation:
Given that :
Riser, AB, Opposite = 10 cm
Thread, = AC, Adjacent = 18 cm
Angle of inclination, θ
Using trigonometry :
Tan θ = opposite / Adjacent = AB / AC
Tan θ = 10 / 18
θ = tan^-1(10/18)
θ = 29.055
Hence, angle of inclination is 29.1° (1 decimal place)

LCD needed to combine the variables: 15
LCD needed to combine the constants: 21
==============================================
Explanation:
If two numbers m and n do not have any common factors (other than 1), then the LCM is m*n. We simply multiply the values.
So for example, the LCM of 2 and 3 is 2*3 = 6.
For the variable terms, the denominators are 5 and 3. So the LCM is 5*3 = 15, and this is the LCD of those variable fractions.
Similarly, the LCD of the constant terms is 21 because 7*3 = 21.
--------
Again, for all of these examples, the two values had no factors other than 1 in common. If you were dealing with something like the LCM of 8 and 12, then the LCM would not be 8*12 = 96. But we can fix things by dividing that by 4 to get 96/4 = 24 which is the true LCM here.
So the more generalized formula would be (m*n)/(GCF of m and n)
This formula works for the previous section because the GCF was 1.
