Paula dives into a swimming pool from a diving board 2 feet above the water's surface. She descends to a depth 7 feet below the diving board. How far is Paula from the surface of the water:
1. What integer represents Paula's starting height above the water?
2. What integer represents the total distance Paula descends?
3. Write an addition expression to represent Paula's distance below the water's surface
4. At the end of her dive, Paula is ____feet below the surface of the water
5. Yolanda owes her friend $15. She also earns $8 each week in allowance. Write and solve an addition equation to show how the total amount of money that Yolanda has will change if she pays her friend back this week.
1) The integer representing Paula's starting height above the water is 2.
2) The integer that represents the total distance Paula descends is 7.
3) An addition expression to represent Paula's distance below the water's surface is 2 + 3.
4) At the end of her dive, Paula is 5 feet below the surface of the water.
5) If Yolanda pays her friend back this week, she will owe her only $7.
What is an integer?An integer is a whole number. It can be positive, negative, or zero but without fractions.
Addition expressions combine two or more addends with the addition operand and equation mark (=) to determine the sum (or the result of the addition operation).
Paula:Height of diving board = 2 feet
Depth of descent below the diving board = 7 feet
Distance below the water's surface = 5 feet (7 - 2)
5 feet = 2 + 3
Yolanda:Debt to a friend = $15
Earnings per week = $8
Total amount after paying friend = 8 - 15
= -$7

Robert has available 400 yards of fencing and wishes to enclose a rectangular area. Express the areaAof the rectangle as a function of the widthwof the rectangle. For what value ofwis the arealargest? What is the maximum area?
Answer:
The answer is below
Step-by-step explanation:
a)Given that the length of fencing available is 400 yards. This means that the perimeter of the rectangle is 400 yards.
the perimeter of a rectangle is given as:
Perimeter = 2(length + width) = 2(l + w)
Hence;
400 = 2(l + w)
200 = l + w
l = 200 - w
The area of a rectangle is given as:
Area = length × width
Area = (200 - w) × w
Area = 200w - w²
b) For a quadratic equation y = ax² + bx + c. it has a maximum at x = -b/2a
Hence, for the area = 200w - w² a=-1, b = 200, the maximum width is at:
w = -b/2a = -200/2(-1) = -200/-2 = 100
A width of 100 yard has the largest area
c) l = 200 - w = 200 - 100 = 100 yards
Area = l × w = 100 × 100 = 10000 yd²
The maximum area is 10000 yd²

How to find the volume of a spherical ball?The bouncy toy company is creating a new rubber bouncing balls for spring toy line they need to know how much rubber each of the spherical balls will hold each ball has diameter of 3.5 inches.
The volume that each ball can hold in cubic inches can be calculated as follows:
The ball is spherical.
Therefore,
volume of the spherical ball = 4πr³
r = 3.5 / 2 = 1.75 inches
Hence,
volume of the spherical ball = 4 × π × 1.75³
volume of the spherical ball = 4 × π × 5.359375
volume of the spherical ball = 21.4375 × 3.14

⎧
−8x+4y=24
−7x+7y=28
x=, equals
y=, equals
Answer:Equation (1):
-8x + 4y = 24
Equation (2):
-7x + 7y = 28
Simplify the equation:
Equation 1 can be simplify by 4:
-2x + y = 6
Equation 2 can be simplify by 7:
-x + y = 4
Add x to both sides of the equation 2:
y = x + 4
Substitute equation 2 into 1:
x + 4 - 2x = 6
x - 2x = 6 - 4
- x = 2
x = - 2.
Substitute - 2 for x in equation 2:
y = - 2 + 4
y = 2.
Therefore, (x, y) = (- 2, 2)

Answer:
\(m = -\frac{194}{3}\)
Step-by-step explanation:
I'm assuming you are trying to find m. In order to do so, you need to get m on one side.
Before doing that let's multiple -2 and -3m by \(\frac{4}{3}\)
\(256=-\frac{8}{3} - 4m\)
add \(-\frac{8}{3}\) to both sides
\(258\frac{2}{3}=-4m\)
I would get rid of the fraction so I'd multiply both sides by \(\frac{3}{1}\)
\(\frac{776}{3}*3 = 4m*3\)
\(776=-12m\)
divide both sides by -12m
\(m = -\frac{776}{12}\)
which can be simplified to
\(m = -\frac{194}{3}\)

Determine the smallest integer value of x in the solution of the following inequality.
-3x+10≤5
Answer: The smallest integer value of x in the solution is 1.
Step-by-step explanation:
The given inequality: \(-3x+10\leq5\)
To solve the inequality, we first subtract 10 from both sides
\(-3x+10-10\leq5-10\\\\\Rightarrow\ -3x\leq-5\)
Multiply negative sign on both sides ,we get
\(3x\geq5\)
Divide both sides by 3, we get
\(x\geq\frac{5}{3}\)
i.e. \(x\geq 1.6666666667\\\)
\(x\geq1\)
Hence, the smallest integer value of x in the solution is 1.

The solution of the given expression is 9*\(x^{4}\)/100.
GIven an expression equal to 27\(x^{12}\)/300\(x^{8}\).
We have to simplify the expression in which variable comes only once.
Expression is combination of numbers ,symbols, fraction, coefficients, indeterminants,determinants, etc. It is mostly not found in equal to form. It expresses a relationship between variables.
The given fraction is 27\(x^{12}\)/300\(x^{8}\).
When we observe we find that in numerator x has large power and denominator x has small power as compared to power in numerator. So we will deduct the powers so that they will give only one power to us.
=27\(x^{4}\)/300
Now divide numerator an denominator by 3.
=9\(x^{4}\)/300
Hence the expression 27\(x^{12} /300x^{8}\) will look like \(9x^{4} /100\) after simplifying.

In a baseball game, a batter standing at home plate sees the second baseman standing on the baseline between 1st and 2nd base as shown in the figure.
If θ=14∘, how far is the second baseman from second base?
Round to the nearest hundredth.
The distance to second base is approximately _________ feet.
The distance to second base is approximately 127.28 feet. Round to the nearest hundredth
How to determine the distance to second baseSince the angle is 45 degrees, the other side of the right triangle are equal, hence we have two sides of 90 ft to be used to find the hypotenuse
Using Pythagoras theorem given by the the formula
hypotenuse² = opposite² + adjacent²
plugging the values as in the problem
let x be the required distance
x² = 90² + 90²
x² = 16200
x = √16200
x = 90√2
x = 127.28 ft (to the nearest hundredth)

Which function is shown in the graph below? On a coordinate plane, a function is shown. The curve starts in quadrant 4 and curves up to quadrant 1. It goes through (0.5, negative 0.4), (1, 0), and (6, 1). y = log Subscript one-sixth Baseline x y = log Subscript 0.5 Baseline x y = log Subscript 1 Baseline x y = log Subscript 6 Baseline x
Answer:
c
Step-by-step explanation:
The y-values of the graph increases as the value of x increases, which
indicates that a characteristic of the base of the logarithm function.
Correct response:
The function that corresponds with the graph is; \(\underline{\mathrm{y = log_6 x}}\)How can the function of a log graph be determined?The given points on the graph are;
The point where the graph starts = Quadrant 4
Direction of the graph = From quadrant 4 to quadrant 1
Points on the graph are;
(0.5, -0.4), (1, 0), and (6, 1)
The given options are;
\(y = \mathrm{log_{\frac{1}{6} } x}\)
\(y = \mathrm{log_{0.5} x}\)
\(y = \mathrm{log_1 x}\)
\(y = \mathrm{log_{6} x}\)
From the shape of the graph, in which, log x increases as x increases, therefore;
The base, b, of the logarithm is larger than 1, given that we have;
\(\mathbf{log_bx} = y\)
\(\mathbf{b^y} = x\)
From the given coordinate points, x increases as y increases, therefore;
b > 1
The possibly option is therefore, y = log₆x
Verifying, we have;
At x = -0.4, y = 0.5
\(b^y = x\)
\(6 ^{(-0.4)}\) ≈ 0.488
Therefore, the point (0.5, -0.4) is close to the graph of y = log₆x
At the point (1, 0), we have;
6⁰ = 1
Therefore, the point (1, 0), is on the graph of y = log₆x
At the point (6, 1), we have;
6¹ = 6
Therefore, the point (6, 1) is on the graph of y = log₆x
The function of the graph is therefore;
