Write the question of the line with the given slope and Y-intercept
Slope = 5
y-intercept =8
Answer:
y = 5x+8
Step-by-step explanation:
I'm assuming you mean to write an equation.
Slope intercept form is y = mx+b
m represents slope
b represents the y intercept
Substitute the values into the equation
We get: y = 5x+8

The Story of Ben and Arthur- Both save $500 per month at 11% compounded monthly. Ben starts at age 19 and stops at age 26, while Arthur starts at age 27 and stops at age 65.
Answer:
Results are below.
Step-by-step explanation:
It is not clear what the question is. But, I will assume that we need to calculate the future value of each investment at age 65.
First, we need to calculate the future value of the monthly deposit made by Ben. We will use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= 500
Interest rate (i)= 0.11/12= 0.0092
Number of months (n)= (26 - 19)*12= 84
FV= {500*[(1.0092^84) - 1]} / 0.0092
FV= $62,944.74
Now, the future value of the investment of Ben at age 65:
FV= PV*(1 + i)^n
n= (65 - 26)*12= 468 months
FV= 62,944.74*(1.0092^468)
FV= $4,574,131.31
Finally, the future value of the investment for Arthur:
i= 0.0092
n= (65 - 27)*12= 456
A= 500
FV= {500*[(1.0092^456) - 1]} / 0.0092
FV= $3,484,032.07
PLEASE HELP FAST Looking for the bottom angle to find my answer! 30 POINTS
x = 242.7 m
Step-by-step explanation:
First we need to find the angle at one of the parachutists:
180 - 57 - 43 = 80°
We then use sine law to find the distance between the parachutists
\( \frac{x}{ \sin(57) } = \frac{285 \: m}{ \sin(80) } \)
Solving for x
\(x = (\frac{ \sin(57) }{ \sin(80) } )(285 \: m) = 242.7 \: m\)

Answer:
615.8
Step-by-step explanation:
Circle area = π * r² = π * 196 [mcm²] ≈ 615.8 [cm²]
Answer:
Area is 616 square centimeters.
Step-by-step explanation:
Area of Circle
\(A = \pi r^2\)
A ... area
r ... radius
Given
r = 14 cm
Use formula.
\(A = \pi r^2\)
\(A = \pi (14 \text{ cm})^2\)
\(A = \pi (196) \text{ cm}^2\)
Use \(\frac{22}{7}\) for \(\pi\), since they tell you to use that in instructions.
\(A = (\frac{22}{7}) (196) \text{ cm}^2\)
\(A = 616 \text{ cm}^2\)

Step-by-step explanation:
hree dice are tossed, one red, one blue, and one green. what outcomes make up the event a that the sum of the three faces showing equals 5?
The outcome that makes up the event a that the sum of the three faces showing equal 5 is; P(E) = 1/36
There are three dice, thus.
Set the Red die to R.
Set the Blue die to B.
Green Dice should be G.
Now, none of the six potential numbers can be bigger than 3 in order for the sum of the three numbers on all dice to equal 5.
So, P(R) = 3/6.
Now, if P(R) = 3/6, none of the other 2 dice can produce 3 or more because doing so would cause the sum to exceed the necessary 5.
So, P(B) = 2/6.
Now that P(R) and P(B) have been obtained, P(Y) must be 1/6.
As a result, P(E) = 3/6 2/6 1/6 is the result that constitutes the event that the sum of the three faces shown equals 5.

3 resistance 5Ω , 7Ω , 9Ω are connected in parallel with a power supply of 9 volt. Calculate its equivalent resistance current passing through each resistance and total current passing through the circuit.
The equivalent resistance currents passing through each resistance are: 1.8 A , 1.29A , 1A.
The total current passing through the circuit is 19.83 A.
How can the current be calculated?The resistance 5Ω , 7Ω , 9Ω which are are connected in parallel, then,
R1 =5Ω,
R 2=7Ω,
R3 =9Ω; supply voltage V=9 volt.
Effective resistance of parallel combination can be calculated as :
1/RP = 1/R1 + 1/R2 + 1/R3
1/RP= 1/5 + 1/7 +1/9
Rp = 0.45397Ω
Then the Current through resistors
are R1, I1 = V/R1 = 9/5 = 1.8A
R2, I2 = V/R2 = 9/7 = 1.29A
R3, I3 = V/R3 = 9/9 = 1A
Then Total current I = V/Rp = 9/ 0.45397 = 19.83 A

A box has a base area of 1.1 m2.
The box is placed on the ground and exerts a force of 4.5 kN.
What pressure is the force applied with?
Give your answer in kN/m2 and rounded to 2 dp.
Answer:
To find the pressure that the box exerts on the ground, we need to divide the force by the area of the base:
pressure = force / area
We are given that the force is 4.5 kN and the area is 1.1 m². However, we need to convert the force from kilonewtons to newtons before we can divide by the area:
force = 4.5 kN = 4,500 N
Now we can plug in the values:
pressure = 4,500 N / 1.1 m² = 4,090.91 N/m²
To express the pressure in kilonewtons per square meter, we need to divide by 1,000:
pressure = 4.09091 kN/m²
Rounding to 2 decimal places, we get:
pressure ≈ 4.09 kN/m²
Therefore, the pressure exerted by the box on the ground is approximately 4.09 kN/m².

Answer:
2a. (360x +495)/(8x +11) = 45
2b. 2((8x+11) +45) = 16x +112
Step-by-step explanation:
a) The area is the product of length and width.
A = LW
We are given ...
W = 8x +11
A = 360x +495
The value of length can be found by solving for L:
L = A/W
L = (360x +495)/(8x +11)
The long-division solution to this is shown in the attachment.
L = 45 . . . . simplified expression for length

y-20 = 0.75(x-4) solve for y
Answer:
y = 0.75x + 17
Step-by-step explanation:
y - 20 = 0.75(x-4)
y - 20 = 0.75(x) + 0.75(-4)
y - 20 = 0.75x -3
y = 0.75x -3 + 20
y = 0.75x + 17
y - 20 = 0.75(x - 4) |add 20 to both sides
y = 0.75(x - 4) + 20we can simplified equation:
use the distributive property: a(b + c) = ab + ac
y = 0.75x - 0.75 · 4 + 20
y = 0.75x - 3 + 20
y = 0.75x + 17Please I need help. And please give me the right answer
Pls answer my q under cause im not sure…
Answer:
v = 13.5 m/s
Step-by-step explanation:
v = u + at
u is initial velocity
a is acceleration
t is time
v is final velocity
using the info in the q, we know
u = 3
a = 1.5
t = 7
sub these numbers into the equation to find v - final velocity
v = u + at
v = 3 + (1.5×7)
v = 13.5 m/s

Yes, the two cones are congruent because they have the same radius, height, and volume, indicating that they share the same shape and size. Their identical properties provide clear evidence of their congruence.
Congruence means that two objects have the same shape and size. In this case, the cones have the same radius, height, and volume, which are all key properties that determine their shape and size.
To demonstrate their congruence, we can examine the relationships between these properties. Since the cones have the same radius, their circular bases are identical in size. The height of the cones is also the same, meaning their slant heights and lateral surfaces are equal.
Additionally, the volume of a cone is calculated using the formula V = (1/3)πr^2h, where r is the radius and h is the height. Given that the volumes of the two cones are equal, it implies that their radii and heights are proportional.
Considering all these factors, we can confidently conclude that the two cones are congruent. Their identical radii, heights, and volumes provide substantial evidence that they share the same shape and size, satisfying the criteria for congruence.
