4.09

Step-by-step explanation

since negatives over power positive numbers

ANTONII [103]

Answer:

10 units

Step-by-step explanation:

Formula to find the distance between two points (x_1,y_1) and (x_2,y_2) is,

d = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Distance between two points (0, -7) and (-6, 1) will be,

d = \sqrt{(0+6)^2+(-7-1)^2}

  = \sqrt{36+64}

  = \sqrt{100}

  = 10

Therefore, distance between the given points is 10 units.

Write the function in standard form.<br> f(x) = - 2(x - 9)2 + 14<br> f(x)=
Archy [21]
F(x) = -2 (x-9)2 + 14
= -4(x-9) + 14
= -2 [ 2(x-9) -7 ]
= -2 (2x -18 -7)
= -2 (2x -25)

Need an answer for the question
inysia [295]

Answer:

x = 8/13

Step-by-step explanation:

6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x

6 - 3x - 9x - 12 = 2x - 14 - x

6 - 12 + 14 = 2x - x + 3x + 9x

8 = 13x

x = 8/13

What is the measure of angle C
maw [93]

Answer:

C = 77°

Step-by-step explanation:

From the intercepted arc theorem, we can say that Angle ABC (angle B) is HALF of the arc intercepted (which is 110).

Hence, angle ABC = 55.

Now, looking at triangle ABC, we know that sum of 3 angles of a triangle is 180. We already know Angle A to be 48 and Angle B to be 55, thus Angle C is:

A + B + C = 180

48 + 55 + C = 180

103 + C = 180

C = 180 - 103

C = 77
