Answer:
New dimension:
Length = 15m
Width = 9m
Step-by-step explanation:
Length = 13m
Width = 7m
Area of a rectangle = length × width
New dimensions:
Length = (13 + x)m
Width = (7 + x)m
Where,
x = increase in each dimension
Area of a rectangle = length × width
(13 + x) × (7 + x) = 135
91 + 13x + 7x + x² = 135
91 + 20x + x² = 135
x² + 20x = 135 - 91
x² + 20x = 44
x² + 20x - 44 =0
Using factorization method to solve quadratic equation
x² - 2x + 22x - 44 = 0
x(x -2) + 22(x - 2) = 0
(x - 2) (x + 22) = 0
x = 2 , x = -22
The increase can not be a negative value
Therefore, the increase in the dimensions is 2 inches
New dimensions:
Length = (13 + x)m
= (13+2)m
= 15m
Width = (7 + x)m
= (7+2)m
= 9m

Which of the following represent an exponential growth function?
Answer:
[tex]y=3^x[/tex]
Step-by-step explanation:
Exponential Growth Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
[tex]C(t)=C_o\cdot(1+r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the (positive) growth rate, expressed in decimal
Since r is positive, 1+r is greater than 1.
From the available options, only the last two of them correspond to exponential functions according to the definition above.
Note the third option has a base of 1/3 which is not greater than 1. In fact, it corresponds to an exponential decay function.
The last option has a base 3 and corresponds to a value of r=2 which correctly fits with the definition presented above, thus the correct choice is
[tex]\mathbf{y=3^x}[/tex]

g(x)= x^2-x-6
g(x)- __(x+__)^2+___
Thanks :)
Step-by-step explanation:
g(x) = x²- x - 6g(x) = x²- 2*1*1/2x + (1/2)² - (1/2)²-6g(x) = (x - 1/2)² - 6 1/4org(x) = (x - 1/2)² - 25/4Answer:
[tex]g(x) = 1 (x+ -\frac{1}{2} )^{2} + -\frac{25}{4}[/tex]

Radha takes some flowers in a basket and visits three temples one by one at each Temple she offer one half of the flowers from the basket if she is left with three flowers at the end find the number of flowers she had in the beginning
Answer:
24
Step-by-step explanation:
She visits 3 temples one by one
She offers 1/2 of what she has in the baske
So 1/2 to the first 1/2 of 1/2 to the second =1/4And 1/2 of 1/2 of 1/2 to the third 1/8She is left with 3 flowers
If she gave 1/2 of what she had left to the 3rd, and the other half was 3
Then it means she gave the 3rd 3 flowers
So 3 is 1/8th of what she had at the beginning
Multiply 3*8 and you get 24

will the inequality "7 multiplied by a number is greater than or equal to 21" have an open boundary point or a closed boundary point on the number line?
Answer:
Closed boundary point
Step-by-step explanation:
It says greater than OR equal too and having a closed boundary will indicate that 21 is apart of the inequality also.

If the sides of a triangle have the following lengths, find a range of possible values for x.
LM = 6x + 3, MN = 4x - 17, LN = x + 40
Answer:
The range of possible values of x are;
x > 6
Step-by-step explanation:
To form a triangle, the length of two sides must be greater than the third side
Thus;
6x + 3 + 4x-17 > x + 40
6x + 4x-14 > x + 40
10x-14 > x + 40
10x-x > 40 + 14
9x > 54
x > 54/9
x > 6

Step-by-step explanation:
Solve for theta to the nearest degree
Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ = [tex]cos^{-1} (5/8)[/tex]
θ=51.3178125...
θ=51°

The equation below describes a proportional relationship between x and y. What is the constant of proportionality? Y=4/7x
Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4
Step-by-step explanation:
Which ordered pair is a solution of the equation?
y = -3x-4.
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer: Only (-3,5)
Step-by-step explanation:
What value of x can you substitute into each of these expressions to give you the same answer?
x + 12
6x - 8
4x
Answer:
[tex]x = 4[/tex]
[tex]4 + 12 = 16 \\ 6 \times 4 - 8 = 16 \\ 4 \times 4 = 16[/tex]
Step-by-step explanation:
x4
\begin{gathered}4 + 12 = 16 \\ 6 \times 4 - 8 = 16 \\ 4 \times 4 = 16\end{gathered}
4+12=16
6×4−8=16
4×4=16
