Answer:
f(8)= 113
Step-by-step explanation:
f(8)= 2(8)^2-3(8)+9
f(8)= 2(64)-3(8)+9
f(8)= 128-24+9
f(8)= 113

convert unit rate 12yd/min = ft/s
Answer:
12 yards per second = 36 feet per second
Formula: multiply the value in yards per second by the conversion factor '3'.
So, 12 yards per second = 12 × 3 = 36 feet per second.
Step-by-step explanation:
To calculate a yard per second value to the corresponding value in ft/s, just multiply the quantity in yd/s by 3 (the conversion factor).
Here is the formula:
Value in ft/s = value in yd/s × 3
Suppose you want to convert 12 yd/s into ft/s. Using the conversion formula above, you will get:
Value in ft/s = 12 × 3 = 36 ft/s
Is this true if yes why/if not why not, give reason.

The cost of a new math textbook and a study guide together is $58. Three of the math textbooks and two study guides cost $165. How much does one textbook alone cost?
Answer:
Cost of one textbook = $49
Step-by-step explanation:
Given:
Cost of 1 textbook and 1 study guide = $58
Cost of 3 textbook and 2 study guide = $165
Find:
Cost of one textbook
Computation:
Assume,
Cost of one textbook = a
Cost of one study guide = b
So,
a + b = 58
b = 58 - a
3a + 2b = 165
3a + 2(58-a) = 165
3a - 2a + 116 = 165
a = 49
Cost of one textbook = $49

A roller coaster climbs to a height of 248m before it goes into an underground tunnel that is 16m below ground. What is the height difference between the highest point and the lowest?
A) -232
B) -264
C) 264
D) 232
===========================================================
Explanation:
Draw a vertical number line. Mark the values 248, 0, and -16 on the number line. The negative value is to indicate it is below 0, while the positive number is above 0.
The distance from 248 to 0 is 248 units. Let A = 248.
The distance from 0 to -16 is 16 units. Let B = 16
The total distance mentioned so far is A+B = 248+16 = 264
So basically if we start at the highest point (248) and go to the ground level, we traveled 248 meters. Then we travel another 16 meters to go from ground level to the lowest point (-16) leading to a total of 248+16=264 meters in total distance from highest to lowest point.

A recipe for cooking turkey states to cook the turkey 15 minutes per pound. Add an additional 5 minutes per pound if the Turkey is stuffed. Our turkey is 16 pounds and will be stuffed. We plan to eat at 1:00 PM. Allow 30 minutes for cooling and carving. What time does the turkey have to be put in the oven?
Answer:
The turkey has to be put in the oven at 7:10 AM.
Step-by-step explanation:
We have:
Turkey stuffed with 16 pounds
Since the time of cooking is 15 minutes per pound with an addition of 5 minutes per pound when the turkey is stuffed, hence we have:
[tex]T = 16 pounds*15 \frac{min}{pound} + 5 \frac{min}{pound}*16 pounds = 320 min = 5 h + 20 min[/tex]
Therefore, the total time of cooking is 320 minutes or 5 hours plus 20 minutes.
If they plan to eat at 1:00 PM with 30 minutes for cooling and carving, then:
[tex]t_{o} = 13 h - 5.33 h - \frac{1}{2} h = 7 h + 10 min[/tex]
Hence, the turkey has to be put in the oven at 7:10 AM.

If the red square has an area of 200 square centimeters and the green square has an area of 60 square centimeters, then was is the area of the yellow square?
Answer:
140
Step-by-step explanation:
You want the area. You do not have to take the square root. First of all you have to assume this is a right angle triangle.
c^2 = b^2 + a^2
c^2 = 200
b^2 = 60
a^2 = ?
200 = 60 + a^2
200 - 60 = a^2
a^2 = 140

Step-by-step explanation:
The length of the garden is 10 feet more than twice its width. The perimeter of the garden is 170 feet.
What are the length and width of the garden?
Answer:
Width is 25 ft
length is 60 ft
Step-by-step explanation:
Here, we want to calculate the length and width of the garden
From the question, we are told that the length is 10 ft more than twice its width
So if the width is x ft
Length = 2x + 10
Mathematically, the perimeter of a rectangle i s 2(l + b)
So;
2(x + 2x + 10) = 170
2(3x + 10) = 170
3x + 10 = 85
3x = 85-10
3x = 75
x = 75/3
x = 25 ft
length is;
2(25) + 10 = 50 + 10 = 60 ft

How much force is needed to accelerate a 90 kg skier 2 m/s2?
options
92 N
180 kg/ms2
180N
45 kg/ms2
subject-science
Answer:third one
Step-by-step explanation:
The amount of force needed to accelerate 90 kg skier to 2 meters will be 180 N.
What is a force?A force is defined as the external agent applied to the objects to displace them from one position to another position or to stop the motion of the object. The unit of measurement of the force is the newton.
Given that the weight of the object is 90 kg and the distance to be displaced is 2 meters. The amount of the force will be calculated as below:-
Force = Mass x Acceleration
Force = 90 x 2
Force = 180 Newton
Therefore, the amount of force needed to accelerate 90 kg of skier to 2 meters will be 180 N.

A landscaping business bought 8 rose bushes and 15 daylilies for $193. They went back later and bought 3 more rose bushes and 12 daylilies for $117. How much does each daylily cost?
Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8
a) What is the y-intercept of y = 3x ?
(b) What is the slope of y = -x - 2 ?
Answer:Q. How would you write the equation with a slope of 2/3 and a y-intercept of -3. answer choices. y=3/2x+3. y=2/3-3. y=2/3x-3. y=2/3x+3. Tags: Question 11.
Step-by-step explanation:
THATS IT I THINK sorry caps
Answer:
0 and - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
y = 3x or y = 3x + 0 has c = 0 ← y- intercept
Thus line passes through the origin
(b)
y = - x - 2 has m = - 1 ← slope
