The area of a garden is (x² + 7x + 10)
square yards. Find the dimensions of the
garden if x= 14.
Answer:
The dimensions are approximentaly 17.44.
Step-by-step explanation:
= x2 + 7x + 10
= 196 + 7x + 10
= 196 + 98 + 10
= 294 + 10
= 304 yards squared
The dimensions of the garden if x= 14 will be approximately 17.44.
What is the area of a square?The area of a square can be calculated as the square of the sides of a given figure.
The area of a square = [tex]side^{2}[/tex]
The area of a garden= (x² + 7x + 10)
= 196 + 7(14) + 10
= 196 + 98 + 10
= 294 + 10
The area of a garden= 304 yards squared
The area of a garden = side × side
√ 304 = side
side = 17.44 yards
Thus, the dimensions of the garden if x= 14 will be 17.44 yards.

A set of cards with a letter on each card as shown below are placed into a bag. Howard picks a card at random from the bag.
Determine the probability that the card is an E
Answer: 1/10 or 10%
Step-by-step explanation:
The required probability that the card is an E will be 0.1%.
What is probability?A Probability can be defined as the ratio of favorable outcomes to the total number of events.
P(E) = Number of favorable outcomes / total number of outcomes
A set of cards has sample = U E A R Q H C H L A
Total number of sample s(n) = 10
We need to find the probability that the card is an E
For probability for E,
p(E)= 1 / 10 = 0. 1%
Thus, the required probability that the card is an E will be 0.1%.

Step-by-step explanation:
Using the area formula of a cone, find the height first.
[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]
Solve for h,
Begin by dividing by [tex]\pi r[/tex]
[tex]\frac{A}{\pi r}=r+\sqrt{h^2+r^2}[/tex]
Subtract r.
[tex]\frac{A}{\pi r}-r=\sqrt{h^2+r^2}[/tex]
Square both sides.
[tex](\frac{A}{\pi r}-r)^2=(\sqrt{h^2+r^2})^2[/tex]
[tex](\frac{A}{\pi r}-r)^2=h^2+r^2[/tex]
Subtract [tex]r^2[/tex]
[tex](\frac{A}{\pi r}-r)^2-r^2=h^2[/tex]
Extract the square root.
[tex]\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =\sqrt{h^2}[/tex]
[tex]\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =h[/tex]
Plug in your values.

(X-2)^2/3 + 13 = 5
Answer:
no solutions
Step-by-step explanation:
(X-2)^2/3 + 13 = 5
Subtract 13 from each side
(X-2)^2/3 + 13-13 = 5-13
(x-2) ^2/3 = -8
Raise each to the 3/2 power
(x-2) ^2/3 ^3/2= -8^3/2
(x-2) = (-512) ^1/2
We cannot take the square root of a negative number and remain in the real number system
There are no solutions
Answer:
No real solutions
Imaginary/complex solutions:
x = 2 +/- 16sqrt(2)i
Step-by-step explanation:
(X-2)^2/3 + 13 = 5
(X-2)^2/3 = -8
(X - 2)² = (-8)³
X - 2 = +/- sqrt(-512)
No real solution
x = 2 +/- 16sqrt(2)i
(2 +/- 16sqrt(2)i - 2)^⅔ + 13 = 5
[(+/- 16sqrt(2)i)²]^⅓ + 13 = 5
(-512)^⅓ + 13 = 5
-8 + 13 = 5
5 = 5

Is (5, 10), (-8, 3), (-1, 7), (-5, 10) A Function ?
Answer:

Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.
If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.

Step-by-step explanation:
70 - 5 = 65
125 - 8 = 117
Find the Greatest Common Divisor of 65 & 117

Which function is the result of vertically shrinking ƒ(x) = (x + 1)2 by a factor of 1∕6?
Question 6 options:
A) ƒ(x) = (6x + 1)2
B) ƒ(x) = (1∕6x + 1)2
C) ƒ(x) = 6(x + 1)2
D) ƒ(x) = 1∕6 (x + 1)2
Answer:
[tex]y=\frac{1}{6}(x+1)^2[/tex] is the result of vertically shrinking
Step-by-step explanation:
Vertical stretch or shrink
[tex]y=c \cdot f(x)[/tex]
a stretch by a factor of c if c>1
a shrink by a factor of c if c<1
c is the factor
We are given that factor = 1/6 <1
So, Vertical shrink
So, [tex]y = \frac{1}{6} \cdot f(x)[/tex]
We are given that [tex]f(x) = (x + 1)^2[/tex]
So,[tex]y=\frac{1}{6}(x+1)^2[/tex]
Option D is true
Hence [tex]y=\frac{1}{6}(x+1)^2[/tex] is the result of vertically shrinking
Answer:
ƒ(x) = (1∕6x + 1)^2

what will happen to the volume of a cylinder if the length if the height is tripled?
A. Double
B. Stay the same
C. Triple
D. 9 times as large
Answer:
Triple
Step-by-step explanation:
V = π * r^2 *h
h is directly proportional to V so when h increases V increases.
This is a linear relationship so if h is tripled the volume will be tripled as well.
if r tripled then V would be 9 times as large since r has a square relationship with V.
If you're unsure about these just plug in number r= 2, h= 4, and perform the operation they ask you to do (triple or double) and you'll always get it right.
What is the slope of the line that passes through (1,-19) and (-2,-7)?
The formula for the slope of a line is m = (y2 - y1) / (x2 - x1).
Point 1 = (1, -19)
Point 2 = (-2, -7)
m = (-7 - -19) / (-2 - 1)
m = (-7 + 19) / (-2 - 1)
m = 12 / -3
m = -4

Jackie has a choice of 3 pairs of shoes, 3 pants, and 4 shirts that can make an outfit for today. Each pair of shoes has a different heel height, each pair of pants is made from a different fabric, and each shirt is a different color.
Jackie randomly picks some clothes.
What is the probability that she chooses an outfit consisting of the flat heel or spike heel shoes, the twill or the denim pants, and the white or black shirt?
2/13+2/13+2/13
= 6/13
Step-by-step explanation:
The probability that she chooses an outfit consisting of the flat heel or spike heel shoes, the twill or the denim pants, and the white or black shirt is given by P ( A ) = 22.22 %
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Jackie has a choice of 3 pairs of shoes, 3 pants, and 4 shirts that can make an outfit for today.
Each pair of shoes has a different heel height, each pair of pants is made from a different fabric, and each shirt is a different color.
So , There are a total of 3 x 3 x 4 = 36 possible outfits.
The number of outfits with the specified choices is:
2 (choices of shoes) x 2 (choices of pants) x 2 (choices of shirts) = 8
Therefore, the probability that Jackie chooses an outfit consisting of the specified choices is:
8 / 36 = 2 / 9 ≈ 0.2222 or about 22.22%
Hence , the probability is P ( A ) = 22.22 %
