Answer:

Normally, sequences don't go behind 1, but let's see for this one.

f(-1) = 1

Step-by-step explanation:

Let's sub for -1 in x.

f(-1) = 2(-1) + 3.

f(-1) = -2 + 3

f(-1) = 1

If the terminal point of ø is (1,0), what is tan ø?
charle [14.2K]

Given:

The terminal point of \phi is (1,0).

To find:

The value of \tan\phi.

Solution:

If the terminal point of \theta is (x,y), then

\tan \theta=\dfrac{y}{x}

It is given that the terminal point of \phi is (1,0).

Here, x-coordinate is 1 and the y-coordinate is 0. Using the above formula, we get

\tan \phi=\dfrac{0}{1}

\tan \phi=0

Therefore, the value of \tan \phi is 0.

Answer:

c

Step-by-step explanation:

Two sum of any two side lengths of a triangle will always be greater than the length of the remaining side

a doesn't work because 8+12=20 and 20 is not greater than 20

b doesn't work because 4+5=9 and 9<10

d doesn't work because 6+6=12 and 12 is not greater than 12

c is the only option where you can take any two sides, add them, and the sum will be greater than the remaining side.

For example, for c,

6+8=14, and 14>10

8+10=18, and 18>6

10+6=16, and 16>8

harkovskaia [24]

Answer:

A) 0.99413

B) 0.00022

Step-by-step explanation:

A) First of all let's find the total grading time from 6:50 P.M to 11:00 P.M.:

Total grading time; X = 11:00 - 6:50 = 4hours 10minutes = 250 minutes

Now since we are given an expected value of 5 minutes, the mean grading time for the whole population would be:

μ = n*μ_s ample = 42 × 5 = 210 minutes

While the standard deviation for the population would be:

σ = √nσ_sample = √(42 × 6) = 15.8745 minutes

To find the z-score, we will use the formula;

z = (x - μ)/σ

Thus;

z = (250 - 210)/15.8745

z = 2.52

From the z-distribution table attached, we have;

P(Z < 2.52) ≈ 0.99413

B) solving this is almost the same as in A above, the only difference is an additional 10 minutes to the time.

Thus, total time is now 250 + 10 = 260 minutes

Similar to the z-formula in A above, we have;

z = (260 - 210)/15.8745

z = 3.15

P(Z > 3.15) = 0.00022
