Answer:The radius of Betelgeuse is about 5 × 1011 meters, and the radius of Venus is about 6 × 106 meters.

Step-by-step explanation:

because the 500 billion Has 11 0s so it will be 5 x 10^11    

6,000,000 has 6 0s so it will be 10^6

It costs Guido $0.20 per minute to forward voicemail messages as texts to his cell phone. He already spent $4 in forwarding mess
Vaselesa [24]

Answer:

10 minutes

Step-by-step explanation:

Let the number of minutes = x

It costs Guido $0.20 per minute to forward voicemail messages as texts to his cell phone. He already spent $4 in forwarding messages this month.

For Guido

$4 + 0.20x

His mom has spent $2 forwarding messages. It costs her $0.40 per minute so she can call long distance.

For his mum

$2 + 0.40x

Guido's mom said they have to spend the same amount.

Equating both Equations together

$4 + 0.20x = $2 + 0.40x

$4 - $2 = 0.40x - 0.20x

2 = 0.20x

x = 2/0.20

x = 10 minutes

Guido can talk for 10 minutes

1.) Evaluate the indicated function, where f(x) = x2 − 8x + 3and g(x) = 7x − 5.
noname [10]

Answer:

1) (f + g) (5) = 18, 2) (f + g) (1/2) = - 13/4, 3) (f - g) (-1) = 14, 4) (f * g) (7) = 456, 5) (f/g) (- 2) = - 3/4, 6) (g ○ f)(x) = 6 x - 23, (f ○ g)(x) = 6 x - 6, 7) (g \circ f) (x) = \frac{9}{x} - 24, (f \circ g) (x) = \frac{1}{x - 2} + 5, 8) (f ○ g)(5) = 3

Step-by-step explanation:

1) (f + g) (x) = x^{2}-8\cdot x + 3 + 7 \cdot x - 5\\(f + g) (x) = x^{2} - x - 2\\(f + g) (5) = 18

2) (f + g) (x) = x^{2} - 7 \cdot x + 4 + 6 \cdot x - 7\\(f + g) (x) = x^{2} - x - 3\\(f + g) (\frac{1}{2} ) = - \frac{13}{4}

3) (f - g) (x) = x^{2} - 3 \cdot x + 4 - 4 \cdot x + 2\\(f - g) (x) = x^{2} - 7 \cdot x + 6\\(f - g) (-1) = 14

4) (f \cdot g) (x) = (x^{2}-4\cdot x + 3) \cdot (3\cdot x - 2)\\(f \cdot g) (7) = 456

5) (f / g) (x)  = \frac{x^{2}-3\cdot x + 2}{4 \cdot x - 8} \\(f / g) (-2) = - \frac{3}{4}

6) (g \circ f) (x) = 3 \cdot (2 \cdot x - 8) + 1\\(g \circ f) (x) = 6 \cdot x - 23\\(f \circ g) (x) = 2 \cdot (3 \cdot x + 1) - 8\\(f \circ g) (x) = 6 \cdot x - 6

7) (g \circ f) (x) = 3 \cdot (\frac{3}{x} - 6) - 6\\(g \circ f) (x) = \frac{9}{x} - 24\\(f \circ g) (x) = \frac{3}{3 \cdot x - 6} + 5\\(f \circ g) (x) = \frac{1}{x - 2} + 5

8) (f \circ g) (x) = 2 \cdot (x^{2} - 5 \cdot x) + 3\\(f \circ g) (x) = 2 \cdot x ^{2} - 10 \cdot x + 3\\(f \circ g) (5) = 3
