Evaluate f(x) when x=-10

Mathematics

adell [148]3 years ago

Answer:

f(x) = 10(10)+3 = 103 when x = 10

Step-by-step explanation:

Given a function piecewise as

f(x) = 2x-4 if -3<x<10

      = x^2+3, if 10<=x<13

We see from the definition of f(x) that the function has domain as (-3,13) and two sets defined from (-3,10) and [10,13).

Since 10 less than or equal to sign is there in the second function interval, we find that 10 is included in that.

Hence for finding f(10) we use the function defined for interval including 10 i.e. x^2+3

Substitute 10 for x in x^2+3

f(10) = 10^2+3

=103

Hence answer is 103

Answer:

Its the second option:

f(x) = (x + 3)(x - 1)(x - 4).

Step-by-step explanation:

As it passes through x = -3 that is one root so one factor is (x + 3).

As it also passes through x = 1 another factor is (x - 1).

Also as it passes through x = 4 the third factor is (x - 4).

Answer:

Hypotenuse = 85 cm

Hypotenuse = 89 cm

Hypotenuse = 103.08 cm (Approx.)

Hypotenuse = 54.71 cm (Approx.)

Step-by-step explanation:

Shape 1

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √36² + 77²

Hypotenuse = √1,296 + 5,929

Hypotenuse = √7,225

Hypotenuse = 85 cm

Shape 2

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √39² + 80²

Hypotenuse = √1,521 + 6,400

Hypotenuse = √7,921

Hypotenuse = 89 cm

Shape 3

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √25² + 100²

Hypotenuse = √625 + 10,000

Hypotenuse = √10,625

Hypotenuse = 103.08 cm (Approx.)

Shape 4

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √17² + 52²

Hypotenuse = √289 + 2,704

Hypotenuse = √2,993

Hypotenuse = 54.71 cm (Approx.)

HELP ASAP CAUSE ITS DUE TODAY AND I DIDN'T FINISH IT!!!!!! <br><br><br>im sorry-!
Serjik [45]

Answer: 1 = 8 cups because 2 x 4 = 8.

2. 35... 7 x 10 = 70, 70 / 2 = 35

      1  

3.  20.53 + 1.55 + 0.02..        line up decimals!

<u> +    1.55</u>

   22.08

4. Mean is average.

so add up all the numbers and divide by the amount of numbers you added

18+9 = 27, 27 + 15 = 42, 42 + 11 = 53, 53 + 13 = 66, 66 + 15 = 81.

81 divided by 6 = 13.5 or 13 1/2.

5. c = 5b

b=55

c = 5 x 55

5 x 55 = 275.

c = 275.

<u>NEXT PAGE</u>

<u></u>

1. 48, 6 x 8 = 48.

2. 6, 4 x 3 = 12, 12 / 2 = 6

       1

3. 9. 12 + 5.78 + 6.01

   5.78

<u>+  6.01</u>

  20.91

4. 36 + 42 + 66 + 54 + 23 = 221, 221 / 5 = 44.2 or 44 1/5

5. t = 20c         c = 21

t = 20 x 21 = 420

t = 420.

Suppose that the mean and standard deviation of the scores on a statistics exam are 78 and 6.11, respectively, and are approxima
kiruha [24]

Answer:

0.7422 = 74.22% of scores are above 74.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 78, \sigma = 6.11

Calculate the proportion of scores above 74.

This is 1 subtracted by the pvalue of Z when X = 74. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{74 - 78}{6.11}

Z = -0.65

Z = -0.65 has a pvalue of 0.2578

So 1-0.2578 = 0.7422 = 74.22% of scores are above 74.
