7. Which of the following systems of inequalities describes the shaded region in the graph below?
Answer:
Step-by-step explanation:
the 2nd choice looks good Emily
y > x
y > x+2
y>x and y>x+2 is the systems of inequalities describes the shaded region in the graph below.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A relationship between two expressions or values that are not equal to each other is called 'inequality.
Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade.
If the symbol ≥ or > is used, shade above the line.
If the symbol ≤ or < is used shade below the line.
y>x and y>x+2 is the inequality describes the shaded region in the graph below as it is greater.
Hence, y>x and y>x+2 is the systems of inequalities describes the shaded region in the graph below.

Answer:
The coordinates of the center of the hyperbola are (1,-3)
Step-by-step explanation:
Equation of a hyperbola:

[tex]\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1[/tex]
In this question, we have that:
[tex]-x_0 = -1 \rightarrow x_0 = 1[/tex]
[tex]-y_0 = 3 \rightarrow y_0 = -3[/tex]
The coordinates of the center of the hyperbola are (1,-3)

Answer:
6.3 years
Step-by-step explanation:
Given
[tex]P = 22400[/tex] --- initial value
[tex]r = 12\%[/tex] -- rate
[tex]A = P(0.88)^t[/tex] --- function
Required
Find t when [tex]A = 10000[/tex]
We have: [tex]A = P(0.88)^t[/tex]
Substitute: [tex]A = 10000[/tex] and [tex]P = 22400[/tex]
[tex]10000 = 22400 * 0.88^t[/tex]
Divide both sides by 22400
[tex]0.4464 = 0.88^t[/tex]
Take log of both sides
[tex]\log(0.4464) = \log(0.88^t)[/tex]
Apply law of logarithm
[tex]\log(0.4464) = t\log(0.88)[/tex]
Solve for t
[tex]t = \frac{\log(0.4464)}{\log(0.88)}[/tex]
[tex]t = \frac{-0.3503}{-0.0555}[/tex]
[tex]t = 6.31[/tex]
[tex]t \approx 6.3[/tex]
Use 3.14 for PI( π )
Diameter: 5 ft
Formula: A= πr2
Answer:
[tex]\boxed {\boxed {\sf 19.625 \ ft^2}}[/tex]
Step-by-step explanation:
The area of a circle is found using this formula:
[tex]a= \pi r^2[/tex]
We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.
r=d/2r= 5 ft/2r= 2.5 ftWe know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.
[tex]a= (3.14)* (2.5 \ ft)^2[/tex]
Solve the exponent.
(2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²[tex]a= (3.14)*(6.25 \ ft^2)[/tex]
Multiply.
[tex]a=19.625 \ ft^2[/tex]
The area of the circle is 19.625 square feet.
What is the slope of the line shown below? (Enter your answer as a decimal if
necessary.)
(-2, 4)
(4,-5)
Answer:
- 1.5
Step-by-step explanation:
Given points
( x1 , y1 ) = ( 4 , - 5 )
( x2 , y2 ) = ( - 2 , 4 )
Now
Slope (m)
= ( y2 - y1 ) / ( x2 - x1 )
= ( 4 + 5 ) / ( - 2 - 4 )
= 9 / - 6
= -1.5

According to the table below, what is the probability that a student chosen at random will be 16 or older?

Probability 0.01 0.25 0.30 0.28 0.15 0.01
A. 0.46 B. 0.83 C. 0.41 D. 0.44
Answer:
probability: 0.44
The probability that a student chosen at random will be 16 or older is 0.44 or 44%.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The probability that a student chosen at random will be 16 or older is the sum of the probabilities of selecting a 16-year-old or older student.
P(16 or older) = P(16) + P(17) + P(18)
P(16 or older) = 0.28 + 0.15 + 0.01
P(16 or older) = 0.44
Therefore, the probability that a student chosen at random will be 16 or older is 0.44 or 44%.

Joe ate twice as many pieces of Halloween candy as Ed. Together they ate 48 pieces.
How many pieces of candy did Ed eat?
A. 12
B. 16
C. 24
D. 32
Answer: 16
Step-by-step explanation:
Let the number of candy Ed took be denoted as "x"
Since Joe ate twice the amount of candy Ed ate, then the number of candies joe ate will be denoted as "2x"
Since all together they ate a total of 48 candies, then the sum of the candies eaten by Joe and Ed is what gives a total of 48
This means:
2x + x = 48
3x = 48
X = 16.

A helicopter pilot sees an island at a 70° angle of depression from the horizontal. In the
diagram, m<1 =70°. What is m<2? How do you know?
Answer:
1231 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.
