A parking space shaped like a parallelogram has a base of 19 feet and a height is 9 feet. A car parked in the space is 14 feet long and 6 feet wide. How much of the parking space is not covered by the car? The area of the parking space not covered by the car is
Answer:
87 feet^2
Step-by-step explanation:
area of the parking space not covered by the car = area of parking space - area covered by the car
area of parking space = area of a parallelogram = base x height = 19 x 9 = 171 feet²
Area of car = area of a rectangle = length x width 14 x 6 = 84 feet²
area of the parking space not covered by the car = 171 feet² - 84 feet² = 87 feet^2
Which graph fits this line? y = 2x + 1
Answer:
Calculating two points and drawing the line between the two.
Explanation:
To find the y-intercept, put x = 0
y = 2 (0) - 1
y = -1
To find the x-intercept, put y = 0
2x - 1 = 0
2x = 1
x = 1/2
Draw your system of axis. Mark -1 on the y-axis, and 1/2 on the x-axis.
Now draw a line through these two ponts. Add arrows.
==============================================
To draw the graph by using points,
let x = -1, then y = 2 (-1) - 1 = -2 - 1 = -3
first point is (-1; -3)
Let x = 0, y = 2 (0) - 1 = -1
Second point is (0; -1)
Let x = 1, y = 2(1) - 1 = 1
Third point is (1; 1)
Plot the three points and draw a line through them. Add arrows to your line.

Re-write the equation without the h component.
a. f(x)=2(3)^(x-2)+2
b. f(x)=1/2(4)^(x+1)
Answer:
[tex]f(x) = 2[\frac{3^x}{9}] + 2[/tex]
[tex]f(x) = 8(4)^x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2(3)^{x-2} + 2[/tex]
[tex]f(x) = \frac{1}{2}(4)^{x+2}[/tex]
Required
Remove the h component
In a function, the h component is highlighted as:
[tex]f(x) = a^{x+h}[/tex]
So, we have:
[tex]f(x) = 2(3)^{x-2} + 2[/tex]
Split the exponents using the following law of indices:
[tex]a^m/a^n = a^{m-n}[/tex]
[tex]f(x) = 2*\frac{3^x}{3^2} + 2[/tex]
[tex]f(x) = 2*\frac{3^x}{9} + 2[/tex]
[tex]f(x) = 2[\frac{3^x}{9}] + 2[/tex]
The h component has been removed
[tex]f(x) = \frac{1}{2}(4)^{x+2}[/tex]
Split the exponent using the following law of indices
[tex]a^{m+n} =a^m * a^n[/tex]
So, we have:
[tex]f(x) = \frac{1}{2}(4)^x * 4^2[/tex]
Express 4^2 as 16
[tex]f(x) = \frac{1}{2}(4)^x * 16[/tex]
Divide 16 by 2
[tex]f(x) = 8(4)^x[/tex]

Answer:
See explanation
Step-by-step explanation:
A. 4.8 divided by 0.6
= 4.8 / 0.6
= 8
b.0.48 divided by 0.06
= 0.48 / 0.06
= 8
c. 8.4 / 0.7
= 12
d. 0.84 divided by 0.07
= 0.84 / 0.07
= 12
e.4.5 divided by 1.5
= 4.5 / 1.5
= 3
f. 0.45 divided by 0.15
= 0.45 / 0.15
= 3
g. 14.4 divided by 1.2
= 14.4 / 1.2
= 12
h. 1.44 divided by 0.12
= 1.44 / 0.12
= 12
If (X+2,4) and (5,y-1 are equal ordered pairs ,Find the value of X and y
Answer:
x = 3, y = 5
Step-by-step explanation:
Since the ordered pairs are equal, then equate the x and y coordinates
x + 2 = 5 ( subtract 2 from both sides )
x = 3
y - 1 = 4 ( add 1 to both sides )
y = 5

Using the Secant and Chord intersection theorem we can say that:
(GE) (FE) = (CE) (DE)
(11 + 7) (7) = (2x - 7 + 9) (9)
(18) (7) = (2x + 2) (9)
126 = 18x + 18
108 = 18x
6 = x

Step-by-step explanation:
solve for the value of k
Answer:
k = 42
Step-by-step explanation:
This is a complementary angle, meaning that the angles formed equal 90 degrees. We know it is complementary because the angle is shown was a tiny square, a sign that it is 90 degrees. Thus, the two angles (k+1) and 47 added together must equal 90. So, we can write an equation:
(k+1) + 47 = 90
k + 1 = 43
k = 42.
Which side lengths form a right triangle? Choose all that apply. 5, the square root of 8, 33 or 8,15,17 or the square root of 2, the square root of 2, 2
Answer:
17² = 15² + 8²
2² = (√2)² + (√2)²
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides. Hence:
33² ≠ (√8)² + 5² (not right triangle)
17² = 15² + 8² (right triangle)
2² = (√2)² + (√2)² (right triangle)
