Answer:

D. the answer cannot be determined​

Answer:

D or C

Step-by-step explanation:

Answer:

The Answer is D 130 degrees

Step-by-step explanation:

The answer is 130 degrees

Since Line SP And line RQ are equal Angle R is 50

Angles P and Q have to be the same so it equals 130

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.

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.

Answer:

1/258 *(t^28)

= t^28 / 4^4

= t^28 4^-4

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]

Answer:

In the triangle ABC,  A is the right angle;  the side "a", opposite to the angle A, is the hypotenuse and side "b" is the leg.

√ (√2)²-1² = √2-1= √1= 1

according to the Pythagorean theorem.

It means that you have the right angled triangle with congruent legs; thus the triangle is isosceles.

Hence, the angles at the base (at the hypotenuse) are congruent and each is equal to  180°-90°/2 = 45°

Answer.  The measure of the angle B is 45°.

Step-by-step explanation:

The required value of the angle B is obtained as 45°.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given problem can be shown in the form of diagram as below,

The measure of given sides and angle of the triangle are as below,

∠A = 90°, a = BC = √2 and b = AC = 1.

Use the trigonometric ratio to obtain,

Sin∠B = BC/AC

⇒ Sin∠B = 1/√2

⇒ ∠B = 45°

Hence, the measure of angle B is given as 45°.

Answer:

Next year Aimee will be 13 years old

Step-by-step explanation:

Let's call Aimee's age A, and Jamie's age J.

From the information given, we have that:

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

So next year Aimee will be 13 years old

Answer:

Aimee will be 13 years old next year/

Step-by-step explanation:

A stands for Aimee, and J stands for Jamie.

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

In conclusion, Aimee will be 13 years old next year.

Answer:

The volume of a cylinder:

[tex]V \approx 150.796[/tex] [tex]ft^3[/tex]

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

[tex]V = \pi r^2h[/tex]

-Use the given height and radius for the formula:

[tex]V = \pi 4^2 3[/tex]

-Then, solve the formula:

[tex]V = \pi \times 4^2 \times 3[/tex]

[tex]V = \pi \times 16 \times 3[/tex]

[tex]V = \pi \times 48[/tex]

[tex]V = 48\pi \approx 150.796[/tex]

So, the volume of a cylinder is approximately [tex]150.796[/tex] [tex]ft^3[/tex] .

Step-by-step explanation:

Please mark brainliest and 5 stars!

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.
