Answer:

- 1/2

Step-by-step explanation:

Slope = y2- y1/x2 - x1

Given

x1 = -3

y1 = 5

x2 = -5

y2 = 6

Therefore

Slope = 6 - 5 /-5 -(-3)

= 6-5/-5+3

= 1/-2

= - 1/2

Answer:

Slope m=-1/2

Step-by-step explanation:

The slope is m=dy/dx=(y2-y1)/(x2-x1), where index 1 refers to the first point (-3,5). The index 2 refers to the second point (-5,6).

We get:

m=(6-5)/((-5)-(-3))=1/(-5+3)=-1/2

Answer:

Switch to the other streaming service

Step-by-step explanation:

So, 96$ with a 12% increase is $107.52.

But if you do 8.75×12 you get $105.

So Clare should switch to the other music stream.

Answer:

Angle ACD = 38°

Step-by-step explanation:

The full, correct question is presented the attached image to this solution.

Given

Point O is the centre if the circle

Points A, B, C and D are points on the circle

Angle AOB = 140°

Angle OAC = 14°

Angle AOB = 2 × (Angle ACB) [angle subtended at the centre of the circle is twice the angle subtended at the circumference of the circle)

140° = 2 × (Angle ACB)

Angle ACB = (140°/2) = 70°

(Angle AOB) + (Angle OAB) + (Angle ABO) = 180° [sun of angles in a triangle is 180°]

But Angle OAB = Angle ABO = a [base angles of an iscosceles triangle are equal since OA and OB are both radii for the circle O)

(Angle AOB) + (Angle OAB) + (Angle ABO) = 180°

140° + a + a = 180°

2a = 40°

a = (40/2) = 20°

Angle OAB = Angle ABO = 20°

Angle CAB = (Angle OAC) + (Angle OAB) = 14° + 20° = 34°

Triangle ADC is an iscosceles triangle, hence,

Angle DAC = Angle ACD = x [base angles of an iscosceles triangle are equal]

But

(Angle DCB) + (Angle DAB) = 180° [Opposite angles of a cyclic quadilateral (a quadilateral inscribed in a circle) sum up to give 180°]

Angle DCB = (Angle DCA) + (Angle ACB) = (x + 70°)

Angle DAB = (Angle DAC) + (Angle CAB) = (x + 34°)

(Angle DCB) + (Angle DAB) = 180°

(x + 70°) + (x + 34°) = 180°

2x + 104° = 180°

2x = 180° - 104° = 76°

x = (76°/2) = 38°

Angle DAC = Angle ACD = 38°

Angle ACD = 38°

Hope this Helps!!!

- A unicycle tire has a radius of 13 inches. About how far will the unicycle travel in 20 rotations?
mario62 [17]

Answer:

1061.32  you made a typo on G

Step-by-step explanation:

To find the distance travelled by the tire we need the circumference of it

The formula for circumference is 2πr we know pi is roughly 3.14 and the radius is 13

we plug the numbers in and get

2* 3.14* 13

6.28*13

81.64

81.64 is the circumference, now we simply just multiply 81.64 by 13 to get 1061.32

Im guessing number G was supposed to be 1061.32 instead of 10,613

HEEELLLLPP!!!!!!!!!! Please help i hate algebra this is so confusing 20 pts
Salsk061 [2.6K]

Answer:

You are right

Step-by-step explanation:

So basically find the absolute maximum of the graph that the function creates, the highest peak is the spot with the greatest y-value, in this case is (60, 1600).

The x-value that creates the greatest y is also the x-value of the vertex for that function of yours (since your function has end behavior of both ends down). To find the x-value of the vertex, get the average of the 2 x-intercepts. So (20+100)/2, which is 60.
