A remote-control airplane is descending at a rate of 24.91 meters per second. What will be its change in height after 3 1/2 seconds? Round your answer to the nearest meter.
Answer:-87
Step-by-step explanation
-24.91 times 3 1/2 equals -87
The change in height after 3 and 1/2 seconds will be 87 meter.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that remote-control airplane is descending at a rate of 24.91 meters per second.
We need to multiply the rate and height will be;
-24.91 x 7/2 = -87 m
Hence, the change in height after 3 and 1/2 seconds will be 87 meter.

4c=12
Step-by-step explanation:
In the chart, it shows 12 and 4 c. Since they equal the same thing, the equation is 4c=12.
What is an equation of the line that passes through the points (0, -5) and
(-5,-1)?
Answer:
we find first slope
m=(-5+1)/(0+5)
m=-4/5
y-y1=m(x-x1)
y+ 5=(-4/5)(x-0)
5y+25=-4x
so equation is. 4x+5y+25=0
Answer:
y=[tex]-\frac{4}{5}[/tex]x-5
Step-by-step explanation:
The coordinates (0,-5) tells us the y intercept of the line, which is -5.
To find the equation of the line, we have to use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex] to find the slope of the line. Plug in the values of the other coordinates (-5,-1) into the equation, which would then leave you with :
m=[tex]\frac{(-1)-(-5)}{(-5)-0}[/tex]
we then solve for m(the slope) and we get:
m=[tex]-\frac{4}{5}[/tex]
so the equation of the line is y=[tex]-\frac{4}{5}[/tex]x-5
Question 6 of 10
What happens to a line when the y-intercept is changed? Check all that apply.
A. As the y-intercept decreases, the graph of the line shifts left.
B. As the y-intercept increases, the graph of the line shifts up.
O c. As the y-intercept decreases, the graph of the line shifts down.
D. As the y-intercept increases, the graph of the line shifts right.
E. As the y-intercept increases, the graph of the line gets steeper.

(100 points, Need help with this ASAP) I bought a used grain silo. I am going to use it as a groom's room at our venue. I am going to paint the inside of it to brighten it up a little. I need to decide how many cans of paint to buy. The silo is 15' across and 10' tall to the top of the cylindrical part. The top of the silo looks like a funnel. It is also 15' across. It is 4' tall. The ceiling is the funnel top. A can of paint covers approximately 400 sq ft. How many cans of paint will I need to buy?
Answer:
2 cans of paint
Step-by-step explanation:
Surface area of an open cylinder = [tex]2\pi rh[/tex]
(where r is the radius and h is the height)
⇒ SA = 2 × [tex]\pi[/tex] × (15 ÷ 2) × 10 = 150[tex]\pi[/tex] ft²
Surface area of an open cone = [tex]\pi r\sqrt{h^2+r^2}[/tex]
(where r is the radius and h is the height)
⇒ SA = [tex]\pi[/tex] × (15 ÷ 2) × √(4² + 7.5²) = 63.75[tex]\pi[/tex] ft²
Total surface area = 150[tex]\pi[/tex] + 63.75[tex]\pi[/tex] = 213.75[tex]\pi[/tex] = 671.52 ft² (nearest hundredth)
If one can of paint covers approx. 400 ft² then 2 cans of paint needed to cover 671.52 ft²

Adam and 3 riends go on holiday together for a week .The costs of the holiday will be shared equally between 4 friends .These are the cost: £1460 for 4 return plane tickets £720 for the accomidation £180 for the car hire for a week . How does adam have to pay for his share of the cost
Answer:
Adam's share is £590
Step-by-step explanation:
Given
Return Ticket = £1460
Accommodation = £720
Car Hire = £180
Required
Determine Adam's share
First, we need to determine the total cost.
Total = Return Ticket + Accommodation + Car Hire
Total = £1460 + £720 + £180
Total = £2360
Next, is to determine the average.
[tex]Average = Total/4[/tex]
[tex]Average = 2360/4[/tex]
[tex]Average = 590[/tex]
Hence;
Adam's share is £590

Answer:
x=10
Step-by-step explanation:
Since the two given expressions are alternate interior angles ( as a result of the parallel line, which are indicated by the arrows on the two lines going through the middle line, the transversal) you can set them equal to each other.
5x-10 = 3x+10
add 10 on both sides
5x = 3x + 20
subtract 3x on both sides
2x=20
divide by 2 on both sides
x=10
Answer:
10=x
40 degrees for both
Step-by-step explanation:
3x+10=5x-10
3x+20=5x
20=2x
10=x
3(10)+10=40
5(10)-10=40

Which of the following best describes the slope of the line below?
A. Zero
B. Undefined
C. Positive
D. Negative
Answer:
Undefined
Step-by-step explanation:
It is undefined because the x value equals multiple y values so the slope is undefined :)
Have a great day!!
Please rate and mark brainliest!!
Answer: Choice B
Undefined
Reason:
Vertical lines always have undefined slopes.
This is because slope = rise/run, but run = 0 for vertical lines. The "run" describes how much the line moves to the right, but such a thing doesn't happen since it's stuck on one x value only.
So we could have something like slope = rise/run = 1/0 = undefined. Dividing over zero is not allowed.

A ship leaves port at noon and has a bearing of S29oW. The ship sails at 20 knots. How many nautical miles south and how many nautical miles west will the ship have traveled by 6:00 PM
Answer:
Approximately [tex]58.2\; \text{nautical miles}[/tex] (assuming that the bearing is [tex]{\rm S$29^{\circ}$W}[/tex].)
Step-by-step explanation:
Let [tex]v[/tex] denote the speed of the ship, and let [tex]t[/tex] denote the duration of the trip. The magnitude of the displacement of this ship would be [tex]v\, t[/tex].
Refer to the diagram attached. The direction [tex]{\rm S$29^{\circ}$W}[/tex] means [tex]29^{\circ}[/tex] west of south. Thus, start with the south direction and turn towards west (clockwise) by [tex]29^{\circ}[/tex] to find the direction of the displacement of the ship.
The hypothenuse of the right triangle in this diagram represents the displacement of the ship, with a length of [tex]v\, t[/tex]. The dashed horizontal line segment represents the distance that the ship has travelled to the west (which this question is asking for.) The angle opposite to that line segment is exactly [tex]29^{\circ}[/tex].
Since the hypotenuse is of length [tex]v\, t[/tex], the dashed line segment opposite to the [tex]\theta = 29^{\circ}[/tex] vertex would have a length of:
[tex]\begin{aligned}& \text{opposite (to $\theta$)} \\ =\; & \text{hypotenuse} \times \frac{\text{opposite (to $\theta$)}}{\text{hypotenuse}} \\ =\; & \text{hypotenuse} \times \sin (\theta) \\ =\; & v\, t \, \sin(\theta) \\ =\; & v\, t\, \sin(29^{\circ})\end{aligned}[/tex].
Substitute in [tex]\begin{aligned} v &= 20\; \frac{\text{nautical mile}}{\text{hour}}\end{aligned}[/tex] and [tex]t = 6\; \text{hour}[/tex]:
[tex]\begin{aligned} & v\, t\, \sin(29^{\circ}) \\ =\; & 20\; \frac{\text{nautical mile}}{\text{hour}} \times 6\; \text{hour} \times \sin(29^{\circ}) \\ \approx\; & 58.2\; \text{nautical mile}\end{aligned}[/tex].

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The following coordinates are from the given graph.
(1, 70), (2, 140), (3, 210), and (4, 280)
Now,
m = (280 - 140)/ (4 - 2) = 140/2 = 70
The equation from the graph can be written as,
y = mx + c
(1, 70) = (x, y)
70 = 70 x 1 + c
c = 70 - 70
c = 0
So,
The equation of the line from the graph.
y = 70x
1 minute = 70 heartbeats.
The heart's resting heart rate is 70 beats per minute.
Thus,
m = (280 - 140)/ (4 - 2) = 140/2 = 70
The equation of the line from the graph.
y = 70x
The heart's resting heart rate is 70 beats per minute.

anu borrows 12,500 as 12% per annum for 3 years at simple interest find the simple interest she has to pay at the end of 3 years
Answer:
The interest is 4,500
Step-by-step explanation:
We use the simple interest formula,
I = Prt
where
I = interest
P = principal amount = 12,500
r = interest rate = 12% = 0.12
t = time = 3 years
I = Prt
I = 12,500 × 0.12 × 3

If x = 9 when y = 36 and x is directly
proportional to y, what is x when y= 6?
Answer:
1.5
Step-by-step explanation:
9 times 4 = 36
1.5 times 4 = 6
If x = 9 when y = 36 and x is directly proportional to y, then x will be 1.5, when y = 6.
What is directly proportional?Let there are two variables p and q
Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called constant of proportionality.
We know that
36 / 9 = 6 /x
Cross multiply;
36 · x = 9 · 6
Simplify;
36x = 54
Divide each side by 36;
36x ÷ 36 = 54 ÷ 36
