what function models the height of the periscope lens at time t? If the periscope reaches its maximum Heught after ascending for 22 seconds, what is the maximum height in feet? ( 24 inches above the surface and ascends at 6 inches per sec.)
Answer:
Step-by-step explanation:
First we are going to find the function which models the height of the
periscope lens at time t.
Let the 2 be height of the periscope.
The height of the periscope at the beginning is 24 inches. It ascends at 6
inches per second. The expression which describes how much it has raised,
at the moment, is 6t.
The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.
To find maximum height of the periscope, we need to evaluate function
for + = 22.
2 = 24 + 6(22)
= 24 + 132
156
Substitute 22 for t.
Multiply.
Maximum height in inches is 156.
We know that 1 foot is 12 inches.
So the function that describes converting feet to inch is y :
= 12x. Where y
represents number of inches and a number of feet.
U = 12.2
156
12x
12
-n=
156
12
2 = 13
Substitute 156 for y.
Divide both sides by 12.
Maximum height in feet is 13.
The height function modeled by the periscope is an illustration of a linear function.
The height function modeled by the periscope is [tex]\mathbf{h(t) = 24+ 6t}[/tex]The maximum height is 156 inchesThe given parameters are:
[tex]\mathbf{Start = 24\ inches}[/tex]
[tex]\mathbf{Rate = 6\ inches/second}[/tex]
The function model of the height is calculated using:
[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]
Where: t represents the time in seconds
So, we have:
[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]
This gives
[tex]\mathbf{h(t) = 24+ 6t}[/tex]
After 22 seconds, the height of the periscope would be
[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]
Multiply
[tex]\mathbf{h(22) = 24+ 132}[/tex]
Add
[tex]\mathbf{h(22) = 156}[/tex]
Hence, the maximum height is 156 inches

Answer:
x=20
Step-by-step explanation:
Answer:
x=20
Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.
Simplifying
3x + 3 = 6x + -57
Reorder the terms:
3 + 3x = 6x + -57
Reorder the terms:
3 + 3x = -57 + 6x
Solving
3 + 3x = -57 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
3 + 3x + -6x = -57 + 6x + -6x
Combine like terms: 3x + -6x = -3x
3 + -3x = -57 + 6x + -6x
Combine like terms: 6x + -6x = 0
3 + -3x = -57 + 0
3 + -3x = -57
Add '-3' to each side of the equation.
3 + -3 + -3x = -57 + -3
Combine like terms: 3 + -3 = 0
0 + -3x = -57 + -3
-3x = -57 + -3
Combine like terms: -57 + -3 = -60
-3x = -60
Divide each side by '-3'.
x = 20
Simplifying
x = 20

Answer:
≈ 404 m²Step-by-step explanation:
Volume of a sphere:
V = 4/3πr³LSA = TSA of a sphere:
S = 4πr²We have V = 764 m³, find the radius:
4/3πr³ = 764r³ = (3*764/4π)r³ = 182.39 (rounded)r = √182.39r = 5.67 m (rounded)Find the surface area:
S = 4*π*(5.67)²S = 404 m² (rounded)[tex] \boxed{\tt{ \bold{Hello\:Mister\:Brainly!}}}[/tex]
____________
Step by step :S = 4πr²
S = 4π × (V = 4/3πr³)²
S = 4π × (764 = 4/3 × 3,14 × r³)²
S = 4π × (764 × 3/4 = 3,14r³)²
S = 4π × (573 ÷ 3,14 = r³)²
S = 4π × (r³ ≈ 182,5)²
S = 4π × (r ≈ 5,67)²
S = 4 × 3,14 × 5,67²
S ≈ 404m²✔

Answer:
40/3
[tex]15 \times x = 200 \\ 15x = 200 \\ x = 200 \div 15 \\ x = \frac{40}{3} [/tex]
The painter should work at least 13.33 hours to earn $200.
What is inequality?An inequality is a mathematical statement showing the non-equal comparison between two expressions.
Given that, a painter earns $15 per hour. We need to find the minimum number of hours he must work to earn at least $200,
So, let the minimum number of hours be x,
15x ≥ 200
This will be the inequality,
To find the minimum number of hours we will find the value of x,
15x ≥ 200
Divide by 15
x ≥ 200/15
x ≥ 13.33
Hence, the painter should work at least 13.33 hours to earn $200.

OPTION 1, 3
Step-by-step explanation:
I don't know how to explain why these are the correct options, except for basing my observations from the given graph.
Option 1: Attah Shipping does deliver a 20-kg package for $60 [as given by coordinates, (20, 60) -- orange line].
Option 3: The 30-kg line is the last, right-most line on the graph. That's the last point where Kwan Shipping's blue line crosses (within the observable region of the graph). If you look carefully, it is the same height as where Attah Shipping's 25-kg mark is. This means that a 30kg package costs $75 for Kwan Shipping, while it costs Attah Shipping $75 to ship a 25kg package. (You could draw a horizontal line across y = 75 to see what I'm talking about).

Answer:

I I can't agree with a b and d cause a shows that -4 he's greater than three but that is wrong because three is greater than -4 and part B shows that -4 is greater than -3 and according to the order of the number line -3 must be greater than negative 4 then part d shows that 3 is less than -4 which is also not correct because 3 is greater than -4 and part C shows the relationship between the plotted points on the number line clearly because 3 is greater than-4

1. What is the Standard Form of the line with x-intercept of 6 and y-intercept of 2?
2x + 6y = 8
6x + 2y = 8
6x + 2y = 12
2x + 6y = 12
Step-by-step explanation:
these intercepts are also points.
for an y- intercept x =0.
for an x- intercept y = 0.
so, we have the points (6,0) and (0, 2).
the regular equation for a line is
y = ax + b
(0, 2) gives us b directly :
2 = a×0 + b = b
and from there with the second point
0 = a×6 + 2
0 = 3a + 1
-1 = 3a
a = -1/3
so, the equation is
y = (-1/3)x + 2
and transform to standard form
3y = -x + 6
x + 3y = 6
that is the same as
2x + 6y = 12 of the answer options.
