Answer:

60 degrees

Step-by-step explanation:

-50*+110*=60

Outside is -50, on the ground is 110

since the ground is positive, you are going to be adding.

-50 + 110

if you are not good at negatives you can rewrite it to say

110-50=60

still the 110 is positive and the 50 is negative.

Hope this helps!

Which is equivalent sin^-1 (cos(pi/2))?Give your answer in radians
NNADVOKAT [17]

Answer:

Given the expression: \sin^{-1}(\cos(\frac{\pi}{2}))

Let the value of the given expression in radians be \theta

then;

\sin^{-1}(\cos(\frac{\pi}{2})) =\theta

\cos \frac{\pi}{2} = \sin \theta              ......[1]

We know the value of \cos \frac{\pi}{2} = 0

Substitute the given value in [1] we have;

\sin \theta = 0

Since, the value of \sin \theta is 0, therefore, the value of \theta is in the form of:

\theta = n\pi ; where n is the integer.

At n =0, 1 and 2, {Since, n is the integer}

Value of  \theta =0, \pi and 2\pi

therefore, the answer in radians either   0 , \pi or 2\pi

which of the following is q point slope equation of a line that passes through the point (5,2)and (-1,-6)
Salsk061 [2.6K]

Answer:y - y1 = m(x + x1)

m = (y2 - y1)/(x2 - x1) = (-6 - 2)/(-1 - 5) = -8/(-6) = 4/3

y - 2 = 4/3(x - 5) is a possible answer

y + 6 = 4/3(x + 1) is also a possible answer

Answer:

Tax is  C 4.12

Tip is  E 15.00

total =94.10

Step-by-step explanation:

Tax = bill * tax rate

      = 74.98 * 5.5%

      = 74.98 * .055

      = 4.1239

To the nearest cent = 4.12

Tip = bill * tip rate

      = 74.98 * 20%

       = 74.98 *.2

       = 14.996

 To the nearest cent = 15.00

The total bill is

Final = bill + tax+ tip

        = 74.98 + 4.12+15

       = 94.10

A line that includes the point (4,1) has a slope of 1 7 . What is its equation in point-slope form?
Sergeeva-Olga [200]

Answer:

y = 17x-67

Step-by-step explanation:

The one point form of line also called slope point form is given by

(y-y_1)=m(x-x_1)

where (x1, y1) is the point and m is slope

Given: (x1, y1) = (4,1) and m= 17

Substituting these values in above equation to find equation in point-slope form

(y-1)=17(x-4)

y-1 = 17x-68

y = 17x-67

the point -slope form of equation y = 17x-67
