Graph y ≤ (x + 2)^2.
Click on the graph until the correct graph appears.
Answer:
the first one is the correct one
Step-by-step explanation:
a great way to check this is to use demos .com
Answer:
its the first one
Step-by-step explanation:
our vertex is (-2,0)
so replace it in the equation y ≤ (x + 2)^2
so, 0 ≤ (-2 + 2)^2
= 0 ≤ (-4)^2
= 0 ≤ 16
look at that statement, is 0 less than or equal to 16? Yes. Therefore it is correct, so you shade out side of the parabola.
TIP: If the parabola opens up and:
y <, then shade outside.
y >, then shade inside.
Do the opposite if the parabola opens down.

Write an exponential function whose graph passes through the given points (0, - 2) and (- 1, - 4)
Answer:
[tex]y = 2(0.5) {}^{x} [/tex]
Step-by-step explanation:
Use the general formula of exponential equation
[tex]y = ab {}^{x} [/tex]
Plug 0,2 into the function
[tex] - 2 = ab {}^{0} [/tex]
[tex] - 2 = a \times 1[/tex]
[tex]a = - 2[/tex]
[tex]y = - 2b {}^{x} [/tex]
[tex] - 4 = - 2b {}^{ - 1} [/tex]
[tex]2 = b {}^{ - 1} [/tex]
[tex] {2}^{ \frac{ 1}{ - 1} } [/tex]
[tex]2 {}^{ - 1} = 0.5[/tex]
B=0.5
[tex]y = 2(0.5) {}^{x} [/tex]

A new car is purchased for 25000 dollars. The value of the car depreciates at 8.25% per year. What will the value of the car be, , after 15 years?
Given:
Price of a new car = 25000
Depreciation rate = 8.25% = 0.0825
Time = 15 years.
To find:
The value of the car after 15 years.
Solution:
The exponential decay model is
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is number of years.
Putting a=25000, r=0.0825 and t=15 in the above formula.
[tex]y=25000(1-0.0825)^{15}[/tex]
[tex]y=25000(0.9175)^{15}[/tex]
[tex]y=25000(0.274847)[/tex]
[tex]y=6871.175[/tex]
Therefore, the value of the car after 15 years will be 6871.175.

~Set up an equation and solve for x :
→ [tex] \large{ \tt{10x + 45 \degree = 75 \degree + 70 \degree}}[/tex] [ Exterior angle is always equal to the sum of two non-adjacent interior angles ]
Add the numbers : 75° & 70°

Since we want to get rid of the constant in the left hand side , subtract 45 from both sides :

→ [tex] \large{ \tt{10x \: \cancel{ + 45 \degree} \: \cancel{ - 45 \degree} = 100 \degree}}[/tex]

In 2005, 8.1 x 10^10 text messages were sent in the United States. In 2010, the number of annual text messages had risen to 1,810,000,000,000. About how many times as great was the number of text messages in 2010 than 2005?
Answer:
2.23456790123 x 10 ^ 2
Step-by-step explanation:
8.1 x 10^10 = 810,000,000,00( 10 Bounces from the decimal point) ( think of it as frog jums each jump is a single multiplication of 10 ^ 1)
1,810,000,000,000 = 1,81 x 10 ^12
1,81 x 10^ 12 - 8.1 x 10^ 10 =22.3456790123 = 2.23456790123 x 10 ^ 2

Circle a is defined as (x+5)^2 + (y+6)^2 + 16, and circle b is defined as (x+3)^2+(y+2)^2 =9. Which transformation of circle a shows that circle b is similar?
Answer:
We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)
Step-by-step explanation:
We should apply a translation prior to determine if both circles are similar. If we translate the circle A to the center of the circle B. The translation needed is the vectorial distance between both centers:
[tex]T(x,y) = B(x,y)-A(x,y)[/tex] (1)
Where:
[tex]T(x,y)[/tex] - Translation vector.
[tex]A(x,y)[/tex] - Location of the center of the circle A.
[tex]B(x,y)[/tex] - Location of the center of the circle B.
If we know that [tex]A(x,y) = (-5,-6)[/tex] and [tex]B(x,y) = (-3,-2)[/tex], then the translation vector is:
[tex]T(x,y) = (-3,-2)-(-5,-6)[/tex]
[tex]T(x,y) = (2,4)[/tex]
We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)

Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
Before we solve the question, we need to know that from the laws of indices:
A^x x A^y = A^(x+y).
7 to the power of 8th power means 7^8
7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.
7 to the power of 3rd power means 7^3
7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.
Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.
