The record high temperature is 124 F the record low temperature for the same state is -8. What is the range integer? (Write and solve equation). Help please :(
Answer:
here it's 124°F so if we subtract 8 in 124 it will be 124-8= 114°F
now the range = height - lowest = 124°- 114°F = 8° F
The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 12 feet, represented by a vertex of (8,12) , and lands 16 feet from the water jet, represented by (16,0) . Write a function in vertex form that models the path of the stream
Answer:
y=-3/16(x-8)^2+12
Step-by-step explanation:
Refer to the vertex form equation for a parabola:
y=a(x-h)^2+k where (h,k) is the vertex.
Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:
0=a(16-8)^2+12
0=64a+12
-12=64a
-12/64=a
-3/16=a
Therefore, your final equation is y=-3/16(x-8)^2+12
Answer:
y = (-5.33)(x - 8)^2 + 12
Step-by-step explanation:
The graph is a parabola which opens down and has its vertex at (8, 12). We can immediately write y = a(x - 8)^2 + 12, knowing that if x = 8, y = 12. To find the coefficient '1', substitute 16 for x and 0 for y:
0 = a(16 - 8)^2 + 12, or
-64a = 12, or a = -64/12 = 5.33
Then the desired function is:
y = (-5.33)(x - 8)^2 + 12

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You spend $56.00 to fill up your tank. How much are you paying in sales tax?
=======================================================
Work Shown:
2.25% = 2.25/100 = 0.0225
2.25% of 56 dollars = 0.0225*56 = 1.26
The amount of sales tax is $1.26
Side note: The total bill is 56 + 1.26 = 57.26 dollars.
Answer:
$1.26
Step-by-step explanation:
So you just have to find 2.25% of 56.
To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:
2.25% of 56
Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:
2.25% × 56
Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.
2.25% = 0.0225
And now you have:
0.0225 × 56
Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.
But once you multiply 0.0225 × 56, you get an answer: 1.26

Fahad is 140 cm tall. Fareed is 1090 mm tall.
Who is taller? How much taller?
Answer:
Fahad is taller with 31 centimeters
Step-by-step explanation:
1090mm=109cm
Fahad is taller than Fareed by 31 centimeters.
1090 mm = 109 cm
140 cm - 109 cm = 31 cm

What is the volume, in cubic in, of a rectangular prism with a height of 12in, a width of 10in, and a length of 12in?
Answer:
840
Step-by-step explanation:
The Volume of rectangular prism is 1440 square inches.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.
Volume is sometimes referred to as capacity.
We have,
Height = 12 inch
Length = 12 inch
width = 10 inch
So, the Volume of rectangular prism
= l w h
= 12 x 12 x10
= 1440 inch²
Thus, the volume of rectangular prism is 1440 inch².

Describe the difference between angles made by secants inside the circle and angles made by secants outside of the circle?
Answer:
The angle made by two secants intersecting outside a circle is half the difference between the intercepted arc measures. When two secants intersect outside a circle, there are three angle measures involved: The angle made where they intersect (angle APB above) The angle made by the intercepted arc CD.

Find the x intercepts of the graph of -6x + 5y =24. State your answers as while numbers or as improper fractions in simplest form.
Answer:
x-intercept: -4
y-intercept: 24/5
Step-by-step explanation:
Firstly you have to isolate the y:
-6x + 5y = 24
5y = 6x + 24
y = (6x +24)/5
Now, just think about the graph: when the function touch the x-axis, the value of y is equal to 0, and when the function touch the y-axis, the value of x is 0, so just put they in the function:
y = (6•0 + 24)/5
y = 24/5
0 = (6x + 24)/5
5•0 = 6x +24
0 = 6x +24
-6x = 24
x = 24/-6
x = -4

Find the value of x
Answer:
The value of x is 18
Step-by-step explanation:
24 x 15 is 360. ( x + 12 ) x 12 = 360 as well. So, 360÷12=30. 30-12 = 18. So the full equation is (18+12)x12=24×15 which are both equal to 360.

Step-by-step explanation:
y-5=2(x+3)
y-5=2x+6
+5 +5
y=2x+11
Answer:
y = 2x + 11
Step-by-step explanation:
Slope-intercept form is y = mx + b.
Here we have y−5=2(x+3), in point-slope form.
Solve this for y: y = +5 + 2x+6, or
y = 2x + 11
