The temperature at midnight is -5°C and is expected to drop 12°
by sunrise. What is the expected temperature at sunrise?
Answer:
-17 degrees Celsius.
Step-by-step explanation:
If the temperature at midnight is -5, and it is supposed to drop 12 more by sunrise, the 12 degrees are subtracted from the initial temperature.
-5 - 12 = -17 degrees by sunrise.

Write an inequality that describes the graph
Answer:
x<4
Step-by-step explanation:
The arrow is facing left, making it less than. Next, the open circle on 4 means that it does not include 4, therefore the inequality is x<4.
The inequality that represents this situation is - ∞ ≤ x < 4.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Assuming the number line is represented by x.
An open circle on the right-hand side of the line at 4 represents it is less than 4.
We can also observe that the line is going infinitely in the direction of negative infinity.
So, this situation can be represented by an inequality of the form
- ∞ ≤ x < 4.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)
Answer:
the answer is A. y=2sin(1/2x)+1
Step-by-step explanation:
I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph
The function that matches the graph is y= 2 sin(1/2x) +1.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
let y = A sin ([tex]\omega[/tex]x + Ф)+ k
T= 4π, w= 2π/T = 1/2
Now, midline= 1/2( max + min)
=1/2(3-1)= 2/2
k=1
and, A= 3-1 = 2
So, y= 2 sin(1/2x + Ф) +1
as, Ф=0
So, y= 2 sin(1/2x) +1

Samantha is trying to complete the Free Throw wellness challenge. In order to earn her chip, she needs to hit 16 out of 20 free throws on the basketball court. Her last three attempts were 12 out of 20, 13 out of 20, and 15 out of 20. How far is her average free throw percentage from the needed free throw percentage to earn the chip? (round to the nearest whole number)
Answer:
83%
Step-by-step explanation:
12 + 13 + 15 = 40
16 x 4 = 64
16 x 3 = 48

What is the value of xin the solution to this system of equations?
y + 2x = -1
y =1/2x+4
Answer:
x = -2.
Step-by-step explanation:
y + 2x = -1
y = -2x - 1
y =1/2x+4
Subtracting the last 2 equations:
0 = -2x - 1/2x - 1 - 4
5 = - 5/2 x
x = 5 / -5/2
= 5 * 2 / -5 = -2.

If you vertically stretch the square root parent function, F(x)= square roor x, by 7 units, what is the equation of the new function?
Answer:
g(x) = 7√x
Step-by-step explanation:
Parent function: f(x) = √x
Parent function vertically stretched by a factor of 7: g(x) = 7√x
The equation of the new function is 7√x.
What is a scale factor?Scale factor is that it is a number that multiplies times a given quantity to produce a smaller or larger version of the original number. The ratio of any two corresponding lengths in two similar geometric figures.
For the given situation,
The equation is F(x) = √x
The parent function is vertically stretched by 7 units.
So, the new function is
⇒ [tex]7(\sqrt{x} )[/tex]
⇒ [tex]7\sqrt{x}[/tex]
Hence we can conclude that the equation of the new function is 7√x.

Find the rate of change
Answer:
25
Step-by-step explanation:
rate of change =change of distance/ change of time
so if you look at the chart you can see these points: (2,50) and (6,150)
change of distance would be 150-50/ change of time which would be 6-2 which equals 100/4 which is 25, the rate of change.

Answer:
72°
Step-by-step explanation:
The full plate has a central angle of 360°.
7/35 × 360° = 72°
Answer:
72°
Step-by-step explanation:
In order to find the value of the central angle, you must first determine what percentage of the plate was broken.
Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.
Now, knowing that a circle consists of 360°, you need to find 20% of 360.
Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .
[tex]\frac{20}{100}=\frac{x}{360}[/tex]
360 x 20 = 7200
7200 ÷ 100 = 72
x = 72
So, the central angle is 72°.

Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720
x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is
3x + 426 = 720 ( subtract 426 from both sides )
3x = 294 ( divide both sides by 3 )
x = 98

A certain high school has 1,488 students. If you subtract the number of girls from boys you get 78. Let x be the number of boys and y be the number of girls.
Answer:
boys = 705
girls = 783
Step-by-step explanation:
We are to find the number of boys and girls in the school
the answer can be determined using simultaneous equation
x = boys
y = girls
y - x = 78 equation 1
y + x = 1488 equation 2
subtract equation 1 from 2
2x = 1410
x = 1410/2 = 705
Substitute for x in equation 1
y - 705 = 78
y = 705 + 78 = 783
