4. As Jody dives below the water, its temperature decreases by 0.3 degrees Fahrenheit per foot that he dives. If
Jody is diving at a rate of 2.5 feet per second and the water at the surface is at a temperature of 68 degrees
Fahrenheit then what is the temperature of the water Jody is in after diving for 20 seconds?
Using proportions and a linear function, it is found that the temperature of the water Jody is in after diving for 20 seconds is of 53 degrees Fahrenheit.
Jody is diving at a rate of 2.5 feet per second, thus, after 20 seconds, his depth is of:
[tex]20 \times 2.5 = 50[/tex]
The temperature at the surface is of 68 degrees. For each foot, it decreases by 0.3 degrees. Thus, the function is:
[tex]T(f) = 68 - 0.3f[/tex]
Jody is at a depth of 50 feet, thus the temperature is T(50).
[tex]T(50) = 68 - 0.3(50) = 53[/tex]
The temperature of the water Jody is in after diving for 20 seconds is of 53 degrees Fahrenheit.

Let $\overline{AB}$ and $\overline{CD}$ be chords of a circle, that meet at point $Q$ inside the circle. If $AQ = 6,$ $BQ = 12$, and $CD = 38$, then find the minimum length of $CQ$.
9514 1404 393
Answer:
2
Step-by-step explanation:
The products of chord lengths are the same for the intersecting chords:
AQ×BQ = CQ×DQ
6×12 = CQ×(38 -CQ)
This gives a quadratic in CQ:
CQ² -38CQ +72 = 0 . . . . . write in standard form
(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic
CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero
The minimum length of CQ is 2 units. (DQ will be 36.)
A rectangular water tank has the following dimension:
Length = 3 feet, Width = 2 feet, Height = 2.5 feet. Find the amount of water it can hold in cubic centimeter.
Answer:
424,752.7 cm³
Step-by-step explanation:
Since you need to convert from English units to Metric units, you can do that first.
Convert each measurement to centimeters instead of feet since your final answer is in cubic centimeters.
1 foot = 30.48 centimeters
Length = 3 ft 30.48cm
----- x ------------ = 91.44 cm
1 1 ft
Width = 2 ft 30.48cm
------- x ------------- = 60.96 cm
1 1 ft
Height = 2.5 ft 30.48cm
-------- x ------------ = 76.2 cm
1 1 ft
The volume is equal to L x W x H
91.44cm x 60.96cm x 76.2cm = 424,752.7 cubic centimeters

Answer:
5
Step-by-step explanation:
To get the Greates Common Factor (GCF) of 225 and 415 we need to factor each value first and then we choose all the copies of factors and multiply them:
225: 3 3 5 5
415: 5 83
GCF: 5
The Greates Common Factor (GCF) is: 5
Answer:
5
Step-by-step explanation:
The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225
The factors of 415 are: 1, 5, 83, 415

Answer:
A scuba diver was exploring a reef 32.12 m below sea level. The diver ascended to the surface at a rate of 8.8 m/min.
a. using the formula d = rt, so 32.12 m = 8.8m/min (t)
b. it is reasonable to write the distance as positive because the diver is accending/ going up the surface

After using the linear equations method we will get 1.76.
What is linear equations?
An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present. A linear equation is one that has a degree of 1 as its highest value. No variable in a linear equation, then, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Are these functions inverses of each other?Be sure to explain how you know they are inverse or why they are not. Show all work necessary.
Answer:
Yes. f(x) and g(x) are inverses of one another
Step-by-step explanation:
[tex]f(x) = - \frac{1}{2} x - 2 \\ y = - \frac{1}{2} x - 2 \\ x = - \frac{1}{2} y - 2 \\ x + 2 = - \frac{1}{2} y \\ - 2(x + 2) = - \frac{1}{2} y \times - 2 \\ - 2x - 4 = y \\ {f }^{ - 1} (x) = - 2x - 4[/tex]
In step 1 we just copied the original function.
In step 2 we substituted y for f(x).
in step 3 we switched the variables.
in step 4 we added 2 to both sides.
in step 5 we multiply both sides by -2
In step 6 we solved for y.
In step 7 is just a fancy way of saying the inverse function f(x) = -2x - 4
Write a quadratic equation in STANDARD FORM given the roots:
1, 1/2
Answer:
f(x) = 2x^2 - 3x + 1
Step-by-step explanation:
The root 1 is associated with the factor (x - 1).
The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)
The quadratic in question is f(x) = (x - 1)(2x - 1). To write this in standard form, perform the indicated multiplication:
f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1
f(x)=10x^2-5x-3, evaluate f(-3)
Answer:
f(-3)= 10(-3)^2 - 5(-3) - 3
=90 + 15 -3
f(-3) = 102

I need help I never got taught how to do this
Answer:
736cm²
Step-by-step explanation:
The surface area of a regular pyramid is equal to:
area of the square base + 1/2ps
where p is the perimeter of the base and
s is the height of the slant line of the pyramid.
In your drawing s = 15cm and the base has four equal lengths of 16cm
So first find the area of the base. Since this is a square, the area is just the
length x the width or 16cm x 16cm = 256cm²
(p) is the perimeter of the base. Find this by adding all four side of the bottom square together which is 16cm + 16cm + 16cm + 16cm or 4 x 16cm which is 64cm.
You already were given (s) which is the height of the slanted side from the base to the pointed top. The drawing gives you this as 15cm.
So plugging all this into the formula, you get:
Surface Area = Area of Base + 1/2 p s
= 256 cm² + [1/2 ( 64cm )(15cm)]
= 256 cm² + {1/2 ( 960 cm²)]
= 256 cm² + 480 cm²
= 736 cm²
