omeWe are asked to find the length of the diagonal of a square with side = 7 ft
So, we can use the Pythagoras Theorem to find its length, since we are dealing with a right anhle triangle that the diagonal determines, being the 7 ft sides the "legs" of the triangle, and the diagonal of the square being the hypotenuse:
[tex]\text{hyp}=\sqrt[]{7^2+7^2}=\sqrt[]{49+49}=\sqrt[]{98}\approx9.899[/tex]which can be rounded to about 9.9 feet for this diagonal.
In the second problem, we are given the value of the diagonal, and we are asked to find the value of the square's sides, so we use Pythagoras again:
[tex]\begin{gathered} 12^2=x^2+x^2=2x^2 \\ 144=2x^2 \\ \frac{144}{2}=x^2 \\ 72=x^2 \end{gathered}[/tex]where we have named "x" the length of the unknown sides of the square, and used that 12 is the length of the diagonal.
We solved for x^2, but now to find "x" (the length of the side) we use the square root property:
[tex]\begin{gathered} x^2=72 \\ x=\sqrt[\square]{72} \\ x\approx8.485 \end{gathered}[/tex]Then the sides of the square must be approximately 8.5 ft if we round the answer to one decimal.

The rectangle has upper-left coordinates (3,-3), upper-right coordinates (7,-3) and area 16 square units.
By these coordinates, we know that it's base length is 7 - 3 = 4 units.
And, since the area of a rectangle is given by it's base length times its height h, which is: 4*h = 16, which implies h = 4 units.
Therefore, the botton coordinates will be (3,-3-4) = (3,-7) and (7,-3-4) = (7,-7)

The plot is shown below;

The labelings are as follows;
x-intercept 1; (-3.5,0)
x-intercept 2; (-2.5,0)
y-intercept; (0,-5)
Vertex; (-3,1)
part b)what is the slope of the line the rest of the question is provided in the picture
Answers
We want to find the slope of the graph. The formula for calculating slope is expressed as
slope = (y2 - y1)/(x2 - x1)
where
y1 and y2 are the y coordinates of initial and final points on the line.
x1 and x2 are the x coordinates of initial and final points on the line.
Locating initial and final points on the line, we have
when x1 = 1, y1 = 2000
when x2 = 2, y2 = 3500
By substituting these values into the formula, we have
slope = (3500 - 2000)/(2 - 1) = 1500/1
Slope = 1500

the circumference of a circle is 22cm. what is the area of 1/10 of the circular region? use π= 22/7
Answers
Answer
(1/10) of Area = 3.85 cm²
Explanation
Circumference of a circle = 2πr
where
π = pi = (22/7)
r = radius of the circle = ?
Circumference = 22 cm
Circumference = 2πr
22 = 2 × (22/7) × r
22 = (44r/7)
(44r/7) = 22
44r = (22)(7)
r = [(22)(7)/44]
r = 3.5 cm
Area of a circle = πr²
We are then asked to find (1/10) of the area of this circle
(1/10) of Area = (1/10) × (22/7) × 3.5²
(1/10) of Area = 3.85 cm²

the current in a stream flows at a rate of 4 mph. A boat travels 9 miles upstream and 9 miles downstream in a total time of 3 hours. What is the speed of the boat in still water?
Answers
The boat is moving at a speed of 8 miles per hours in still water.
How to find the speed of the boat in still water?
In this problem we find that the absolute speed of a boat (v''), in miles per hour, is the combination of the speed of the boat in still water (v) and the stream speed (v'), in miles per hour. If we assume that the boat travels at constant speed, then we have the following two equations:
Upstream
v - v' = x / t
v - 4 = 9 / t (1)
Downstream
v + v' = x / (3 - t)
v + 4 = 9 / (3 - t) (2)
By (1) and (2):
4 + 9 / t = 9 / (3 - t) - 4
9 / t - 9 / (3 - t) = - 8
9 / (3 - t) - 9 / t = 8
9 · t - 9 · (3 - t) = 8 · t · (3 - t)
9 · t - 27 + 9 · t = 24 · t - 8 · t²
18 · t - 27 = 24 · t - 8 · t²
8 · t² - 6 · t - 27 = 0
By quadratic formula we find that t₁ = 9 / 4 h and t₂ = - 3 / 2 h. Only the first root is physically reasonable. Finally, we find the speed of the boat in still water:
v - 4 = 9 / t
v = 4 + 9 / t
v = 4 + 9 / (9 / 4)
v = 8 mi / h
The speed of the boat in still water is equal to 8 miles per hour.

Answers
An equation for S in terms of n representing Dianelys' salary after working n years for the company is equal to S = 40000 + 2500(n-1).
As given in the question,
Dianelys' first year salary is equal to $40000.
Raise given to Dianelys' every year is $2500
Table to represent the value for different years
First year = $40000
Second year = 40000 + 2500(1)
= $42500
Third year = 42500 + 2500
= 45000
= 40000 + 2500(2)
Fourth year = 45000 +2500
= $47500
= 40000 +2500(3) .....
An equation for S in terms of n years
S = 40000 + 2500(n -1)
Therefore, an equation for S in terms of n representing Dianelys' salary after working n years for the company is equal to
S = 40000 + 2500(n-1).

Using the length of shadow, the height of the building to the nearest tenth is 23.4 metres.

The height of the building can be found as follows:
This situation forms a right angle triangle.
Therefore, the length of the shadow is the adjacent side and the distance from the top of the building to the tip of the shadow is the hypotenuse side.
Hence, using Pythagoras theorem,
c² = a² + b²
35² - 26² = b²
1225 - 676 = b²
