Gianna used two refrigerators, each set to a different temperature, to cool two cups of hot liquid.
She placed the first cup in refrigerator A. The temperature, in degrees Fahrenheit, of the liquid in this cup, after x minutes in the refrigerator, is represented by the graphed function.
She placed the second cup in refrigerator B. The temperature, in degrees Fahrenheit, of the liquid in this cup is represented by an exponential function that has a y-intercept of 96 and approaches 38 as x increases.
When Gianna initially placed two cups in the refrigerators, the liquid placed in refrigerator A was ____ than the liquid placed in refrigerator B. The ____ of the two functions implies that refrigerator A is set to a ____temperature than refrigerator B.
1a. Cooler
1b. Warmer
2a. Y-intercepts
2b. End behavior

Answer: B. 16
Step-by-step explanation:
1,536/6=256
256 squared=16
Answer:
B. 16
Step-by-step explanation:
You need to work on the equation backwards. You know the answer, but you don’t know x. first, you divide 1536 by 6. you will get 256. next, you find the square root of 256. the square root of 256 is 16, so the answer is 16 :)

Mr. Blue drove from Allston to Brockton, a distance of 105 miles. On his way back, he increased his speed by 10 mph. If the journey back took him 15 minutes less time, what was his original speed?
Answer:
His original speed was 60 mph.
Step-by-step explanation:
The average speed formula is shown below:
speed = distance / time
For the first leg of the trip Mr. Blue drove at a speed of "x" mph, for a distance of 105 miles, therefore the time that took to complete the trip is:
time 1 = distance / speed
time 1 = 105 / x h
On the second leg of the trip Mr. Blue drove faster at a speed of "x + 10" mph, so the time it took him to complete the trip was 15 minutes less, therfore:
time 2 = time1 - (15/60) = (105/x) - 0.25 = (105 - 0.25*x)/x h
Applyint the time and speed from the second leg to the average speed formula we have:
x + 10 = {105/[(105 - 0.25*x)/x]}
x + 10 = 105*x/(105 - 0.25*x)
(x + 10)*(105 - 0.25*x) = 105*x
105*x + 1050 -0.25*x² - 2.5*x = 105*x
-0.25*x² -2.5*x + 1050 = 0 /(-0.25)
x² + 10*x - 4200 = 0
x1 = [-(10) + sqrt((10)² - 4*(1)*(-4200))]/2 = 60
x2 = [-(10) - sqrt((10)² - 4*(1)*(-4200))]/2 = -70
Since his speed couldn't be negative the only possible value was 60 mph.
Answer:
60 mph

The simplified form of an expression is StartFraction 1 Over 256 EndFraction t Superscript 28. Which expression was simplified?
A.(256 t Superscript negative 7 Baseline) Superscript 4
B.(4 t Superscript 28 Baseline) Superscript negative 4
C.(256 t Superscript negative 7 Baseline) Superscript negative 4
D.(4 t Superscript negative 7 Baseline) Superscript negative 4
Answer:
1/258 *(t^28)
= t^28 / 4^4
= t^28 4^-4
= (t^-7 * 4)^-4
= (4t^-7)^-4
The simplified form of an expression [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .
What is simplified form ?Simplified form a rational expression is considered simplified if the numerator and denominator have no factors in common.
We have,
[tex]\frac{1}{256} * t^{28}[/tex]
Now to simplify it,
Convert [tex]256[/tex] into a exponent form with a base.
i.e.
[tex]\frac{1}{4^4} * t^{28}[/tex]
Now,
Using the exponent rule;
[tex]\frac{1}{a^n}= a^{(-n)}[/tex]
So,
[tex]4^{-4}\ *\ t^{28}[/tex]
Now, simplify it more by taking common power of [tex]4[/tex] and [tex]t[/tex] ,
[tex](4\ *\ t^{-7})^{-4}[/tex]
⇒ [tex](4 t^{-7})^{-4}[/tex]
So, this is the simplified form of given expression which is given in option number [tex](D).[/tex]
Hence, we can say that the simplified form of an expression [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .

Using sine and cosine, explain how you know where the graph of tangent will
have vertical asymptotes and x-intercepts.
Remember how the tangent function is defined as
[tex]\frac{sinx}{cosx}[/tex]
Now where exactly are the vertical assymptotes? Well, where cosx = 0, because anything over 0 is undefined, and where a value is undefined, you are required to draw a vertical assymptote.
Now where exactly are the x interecepts? Well, where sinx = 0, because remember, an x-intercept is where y = 0, or where it crosses the x-axis, meaning where the tangent function is equal to 0.
So the x-intercepts are at where sinx = 0.
Graph of the tangent will have vertical asymptotes when cosine function is 0 and has x intercept when sine function is 0.
What is Tangent function?Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.
Tangent function can be defined as,
f(x) = tan (x) = [tex]\frac{sin(x)}{cos (x)}[/tex]
Vertical asymptote of a function is the line x = m, where the graph of the function will move to infinity when x approaches m.
Here the function is tan (x).
tan (x) → ∞, when [tex]\frac{sin(x)}{cos (x)}[/tex] → ∞
[tex]\frac{sin(x)}{cos (x)}[/tex] → ∞, when cos (x) = 0, then x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], .......
Vertical asymptotes will be line through x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], ±[tex]\frac{5\pi }{2}[/tex], .....
x intercept is the point, where the y value equals 0.
That is, tan (x) = 0, at the point of x intercept.
[tex]\frac{sin(x)}{cos (x)}[/tex] = 0
⇒ sin (x) = 0
⇒ x = 0, π, 2π, .....
So tan(x) will have the x intercepts at x = 0, π, 2π, .....
Hence the vertical asymptotes and x intercepts of tan function can be found using sine and cosine.

Step-by-step explanation:
Solve the following equation algebraically: x squared = 50
Answer:
x = ±5sqrt(2)
Step-by-step explanation:
x^2 = 50
Take the square root of each side
sqrt(x^2) = ±sqrt(50)
x = ±sqrt(25*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(25)*sqrt(2)
x = ±5sqrt(2)
