QUESTION 2:
The area of the polygon is 21.5 units²
QUESTION 3:
The area of the combined figure is 12 + 18.25·π units²
QUESTION 4:
The area of the figure is 40 units²
QUESTION 5
The area of the compost shape is 40 in.²
Step-by-step explanation:
QUESTION 2.
The area of the polygon is given as follows;
The area of two triangles + The area of trapezoid
1/2×6×3 + 1/2×3×4 + 1/2×(6 + 7) = 21.5 units²
QUESTION 3
The diameter of the semicircle, 'd', is given as follows;
d = √(8² + 3²) = √73
The area of the semicircle = π·d²/4 = π·73/4 = 18.25·π unit²
The area of the right triangle beside the semicircle is given as follows;
1/2 × 8 × 3 = 12 unit²
The area of the combined figure = The area of the semicircle + The area of the right triangle
∴ The area of the combined figure = 12 + 18.25·π units²
QUESTION 4:
The dimensions of the parallelogram are;
Width, W = √(4² + 1²) = √(17)
Length, L = √(8² + 2²) = √(68)
The area of the parallelogram, [tex]A_R[/tex] = W × L = √(17) × √(68) = √(17 × 68) = 34
The area of the parallelogram, [tex]A_R[/tex] = 34 units²
The length of a parallel side, 'A', of the parallelogram is A = 6
The height of the parallelogram, is h = 1
The area of the parallelogram is A = B·h = 6 × 1 = 6 units²
The area of the figure is the sum of the area of the rectangle and the area of the parallelogram
Therefore, we have;
The area of the figure = 34 units² + 6 units² = 40 units²
QUESTION 5
The composite shape consists of a triangle and a rectangle
Therefore, we have;
The area of the rectangle = 5 in. × 7 in. = 35 in.²
The area of the triangle = 1/2 × 2 in. × 5 in. = 5 in.²
The area of the compost shape = The area of the rectangle + The area of the triangle
∴ The area of the compost shape = 35 in.² + 5 in.² = 40 in.²
The area of the compost shape = 40 in.².
please help me im begging you
Answer:
9x + 14
Step-by-step explanation:
You need to add like terms. Add your x's together and your constants together:
5x + 4x + 6 + 8
9x + 14
Answer:
9x+14
Step-by-step explanation:
When you simplify the 5x+4x because they are like terms you just at them together. And 8+6 is 14 so you equation becomes 9x+14. You can't take it any farther than that.
The expression 16t power 2 represents the distance in feet an object falls after t second a. Write an expression representing the height of the object t seconds after it is dropped b. What is the height of subject 3 seconds after this dropped
Answer:
[tex]H(t) = 16t^2[/tex]
Height 3 seconds after is 144ft
Step-by-step explanation:
Given
Expression: 16t power 2
Solving (a): Write as an algebraic expression.
Let H represent the height after t seconds.
So, we have:
[tex]H(t) = 16t^2[/tex]
Solving (b): The height after 3 seconds
This implies that:
[tex]t = 3[/tex]
Substitute 3 for t in [tex]H(t) = 16t^2[/tex]
[tex]H(3) = 16 * 3^2[/tex]
[tex]H(3) = 16 * 9[/tex]
[tex]H(3) = 144[/tex]
Hence, the height is 144ft

Find the distance between each pair of points in the coordinate plane.
1. (0, 0) and (0, 3)
2. (0, 0) and (4, 0)
3. (0, 0) and (4, 3)
4. (0, 0) and (8, 6)
Answer:
1) 3 units
2)4 units
3) 5 units
4)10 units
Step-by-step explanation:
We can use the Distance Formula to find the distance between the two points given to us. The Distance Formula is for points (x1 , y1) & (x2 , y2) is
★ Distance = √[ (x2 - x1)² + (y2 - y1)²]
1) (0,0) & (0,3)
⇒ Distance = √ [ (3-0)²+(0-0)² ]
⇒ Distance = √ [ 3² ]
⇒ Distance = 3 units .
====================================
2) (0,0) & (4,0)
⇒ Distance = √ [ (4-0)²+(0-0)² ]
⇒ Distance = √ [ 4² ]
⇒ Distance = 4 units .
====================================
3) (0,0) & (4,3)
⇒ Distance = √ [ (3-0)²+(4-0)² ]
⇒ Distance = √ [ 3²+ 4² ]
⇒ Distance = √ 9 + 16
⇒ Distance = √25
⇒ Distance = 5 units .
====================================
4) (0,0) & (8,6)
⇒ Distance = √ [ (8-0)²+(6-0)² ]
⇒ Distance = √ [ 8²+ 6² ]
⇒ Distance = √ 64 + 36
⇒ Distance = √100
⇒ Distance = 10 units .

2. The coordinates of ADEF are D(4, 3).
E(7,3), and F(6,8). If you translate ADEF
4 units left and 3 units up, what are the
coordinates of F?

-10-9-8-7-6
1 2 3
X as
9 10
-1
-3
-5
-9
-10

Answer: Hence, the coordinates of F =(2,11)
Step-by-step explanation:
Translation rule to move a figure with coordinates (x,y) by h units left and k units left:
[tex](x,y)\to (x-4,y+3)[/tex]
Coordinates of F = (6,8).
After translation of 4 units left and 3 units up, the coordinates of F = [tex](6-4,\ 8+3)=(2,\ 11)[/tex]
Hence, the coordinates of F =(2,11)

the item is 8%. What is the sales tax and
total cost?
Answer:
Tax: $3.20

Step-by-step explanation:
A) make U subject of the formula E= m/2g(v^2-u^2)
Answer:
u = v2−2Egm−−−−−−−√
Step-by-step explanation:
2Eg = 2g (M2g(V2−U2)
2Eg = m(V2 - U2)
2Eg - mV2 - mU2
mU2 = mV2 - 2Eg
mU2m=mV2−2Egm
U2 = mV2−2Egm
= mV2m−2Egm
U2 = V2 - 2Egm
U = V2−2Egm−−−−−−−−√

A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or F = $2.25 + $0.20(m - 1) where F is the fare and m is the number of miles.
if juan's taxi fare was $7.65 how many miles did he traavel in the taxi
Answer: Juan travelled 28 miles in the taxi
Step-by-step explanation:
A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile. This means that for m additional miles, the charge will be 2.25 + 0.20(m - 1)
So if F represents the fare, then
F = $2.25 + $0.20(m - 1)
If Juan's taxi fare was $7.65, to determine the number of miles that she paid for, we would substitute F = $7.65 into the equation,
F = $2.25 + $0.20(m - 1). It becomes
7.65 = 2.25 + 0.20(m-1)
7.65 = 2.25 + 0.20m - 0.20
7.65 - 2.25 + 0.20 = 0.2m
0.2m = 5.6
m = 5.6/0.2 = 28 miles
Answer:
Juan traveled 28 miles in the taxi
Step-by-step explanation:
7.65=2.25+0.2(m-1), subtract 2.25 from both sides, then you get 5.40=0.2(m-1)
then multiply 0.2 by the numbers in the parenthesis and get 5.40= 0.2m-0.2
add 0.2 to both sides to get 5.60 = 0.2m, divide both numbers by 0.2 and get 28 = m

Answer:
Slope=3 y intercept=(0,-1) Second graph: Linear. Third graph: Non linear
Step-by-step explanation:
I recommend using math w ay algebra problem solver to get answer on the first question.
Answer:
1) slope = 3
y-intercept = -1
2) linear
non-linear
Step-by-step explanation:
In the equation y=mx+b, m is the slope and b is the y-intercept. The number next to the x will always be the slope, and the number after represents the y-intercept.
Linear graphs are always straight lines, the values are always constant.
Non-linear graphs are graphs with curves.

how to tell if a complex solution is real or imaginary?
Answer:
The expression b2 − 4ac is called the discriminant, and can be used to determine whether the solutions are real, repeated, or complex: 1) If the discriminant is less than zero, the equation has two complex solution(s). 2) If the discriminant is equal to zero, the equation has one repeated real solution(s).
Answer:
If a parabola has a descrimant is less than zero its solution is imaginary, if it is equal to 0 it has one solution and if it is greater than 0 it has 2 solutions. The discramanant can be written as b^2 - 4ac and it is the area under the square root in the quadratic equation.
