Answer:
y² - y - 2
Step-by-step explanation:
Quadratic functions can be solved using the roots. To solve for roots, we set the two factors equal to zero and solve for the variable. So, we are going to reverse that here.
y + 2 = 0
y = -2
y - 1 = 0
y = 1
Then, we know our factors are (y - 2) and (y + 1), so we just FOIL these.
(y - 2)(y + 1)
y² + 1y - 2y - 2
y² - y - 2
This would be our final equation.

Answer:
41 y/oStep-by-step explanation:
its a ratio and proportion:
18 y/o = 82 y/o
9 y/o x
82(9) = 18(x)
x = 738 / 18
x = 41 y/o

carlton thinks that converting metric units is as easy as moving the ________
Answer:
Carlton thinks that converting metric units is as easy as moving the decimal pointStep-by-step explanation:
When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.Example:
1 meter = 1000 millimeters (1.0 m = 1000.0 mm) 1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)see attached for prefixes
Answer:
decimal point
Step-by-step explanation:
To convert a metric unit, you are going to either multiply or divide.
Some examples include:
km/1000 = mm/100 = cmcm/10 = mmmm*10 = cmcm*100 = mm*1000 = kmBest of Luck!
in the diagram the value of sin P is
You divide the opposite over the hypotenuse
sin(angle) = opposite/hypotenuse
With respect to reference angle P, the opposite side is QR = 5 since it is the leg furthest from the angle P.
The hypotenuse is always the longest side and always opposite the 90 degree angle (the largest angle of any right triangle).
An object is moving at a speed of 7 feet per minute. Express this speed in meters per second.
Answer:
2.1 mpm
Explanation:
1ft = 0.3048 m
[tex]0.3048*7=2.1336[/tex]
The given speed in meters per second is 0.00356 m/sec.
Given that, an object is moving at a speed of 7 feet per minute.
We need to express this speed in meters per second.
How to convert feet per minute to meters per second?Feet per minutes. In SI units [tex]5.08 \times 10^{-3}[/tex] meters per second.
Meters per second is the base unit for measuring velocity or speed in the International System of Units (SI). Speed is a measure of distance travelled over time, velocity is speed in a given direction. 1 meter travelled over a period of 1 second = 1 m/s.
For an approximate result, divide the speed value by 1969.
Now, 7/1969=0.003555
≈0.00356
Therefore, the given speed in meters per second is 0.00356 m/sec.

5) x = 8
6) z = 49°
Step-by-step explanation:Hi there !
5)
we have opposite angles =>
5x = 2x + 24
5x - 2x = 24
3x = 24
x = 24 : 3
x = 8
6)
The sum of the three interior angles in a triangle is always 180° !
x = 180° - (28° + 39°)
= 180° - 67°
= 113°
x ; y = supplementary angles =>
x + y = 180° =>
y = 180° - x
= 180° - 113°
= 67°
z = 180° - (64° + 67°)
= 180° - 131°
= 49°

Econo motel charges $260 for 4 nights. At that rate, how much would 7 nights cost
Divide the cost for 4 nights by 4 to get cost per night.
260/4 = 65 per night.
Multiply cost per night by 7:
65 x 7 = 455
It would cost $455 for 7 nights.

1) -1 3/5
2) -2/5
3) 1/2
4) 1 3/5
Answer: -2/5
Step-by-step explanation: It's -4/5 multiplied by 1/2 because you you have to find the reciprocal, so you flip 2, so it would become 1/2, then you multiply -4/5 and 1/2, which would get you -4/10, which can be reduced to -2/5. Hope this helps!
