Answer:

7.44 × 10⁹

Step-by-step explanation:

You would take a decimal point from the last zero to in-between 7 and 4 and see how many places you moved it then write the scientific formula.

9 spaces so it would be 7.44 × 10⁹

Write the equation of the circle with the given center and radius.
34kurt

Step-by-step explanation:

The standard equation of a circle is (x - h)^2 + (y - k)^2 = r^2

Center = (h, k)

#1

Center = (0,2)

h = 0

k = 2

r = 5

(x - h)^2 + (y - k)^2 = r^2

(x - 0)^2 + (y - 2)^2 = 5^2

#2

Center = (-4,-5)

h = -4

k = -5

r = \sqrt{2}

(x - h)^2 + (y - k)^2 = r^2

(x - (-4))^2 + (y - (-5))^2 = \sqrt{2}^2

(x + 4))^2 + (y + 5))^2 = \sqrt{2}^2

#3

Center =(-1,3)

h = -1

k = 3

r = 8

(x - h)^2 + (y - k)^2 = r^2

(x - (-1))^2 + (y - 3)^2 = 8^2

(x + 1)^2 + (y - 3)^2 = 8^2

#4

Center: (9,0)

h = 9

k = 0

r = \sqrt{3}

(x - h)^2 + (y - k)^2 = r^2

(x - 9)^2 + (y - 0)^2 = \sqrt{3}^2

How many triangles can be made if one angle is 95° and another angle is acute?
Oksana_A [137]
Theoretically, the answer will be infinite.

Since one angle of 95 degrees means the other two angles must be acute. You can pick any two real numbers with the sum of 85.
