Consider the functions f(x) = x^2 -1 and g(x) = 3x+1. Find the value of f(4) and g(4)

1 answer:

7 0

All you do here is plug in 4 for the x values.

So F(4)=4^2-1 which is F(4)=16-1 so F(4)= 15

So G(4)= 3(4)+1 which is G(4)=12+1 so G(4)=13

Find the exact value of the indicated trigonometric function of θ.

Mariana [72]

Answer:

cosθ = -√(35/36)

tanθ = -1/√35

Step-by-step explanation:

We know that

sin²θ + cos²θ = 1

(1/6)² + cos²θ = 1

1 - (1/6)² = cos²θ

35/36 = cos²θ

sec θ = 1/ cosθ

1/ secθ = cos θ

Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0

cosθ = -√(35/36)

tanθ = sinθ/cosθ = (1/6)/-√(35/36)

= (1/6) / -(√35/6)

= -1/√35

For the past 25 days, jonathon has read for n minutes each day. His total number of minutes read is 875. Write an equation to ex

liubo4ka [24]

Answer:

Required equation is: 25n = 875

Step-by-step explanation:

Let n be the number of minutes Jonathon read per day

Now

He read for 25 days and total 875 minutes

The equation will be:

$25n = 875$

We can solve this equation to find the number of minutes each day

Using Division property of Equality

$\frac{25n}{25} = \frac{875}{25}\\n = 35$

Hence,

Required equation is: 25n = 875

Which of the following equations is equivalent to 2 + x + 2x = 14? A 4X E 14 B 3x = 12 C 3x = 16 D 1x = 12

Alex_Xolod [135]

Step-by-step explanation:

2 + x + 2x = 14

3x + 2 = 14 (combine like terms)

3x = 12 (subtract 2 from both sides)

Hence the answer is 3x = 12. (B)
