F(x) = 2 + x^2, evaluate f(7)

Pachacha [2.7K]

$\begin{gathered} f(x)=2+x^2 \\ f(7)=2+(7)^2 \\ f(7)\text{ = 2 + 49} \\ f(7)\text{ = 51} \end{gathered}$

Result

f(7) = 51

BD−→− bisects ∠ABC such that m∠ABD = (4x−5)∘ and m∠DBC = (3x+2)∘.

Rzqust [24]

Answer:

$\angle ABC=(46)^{\circ}$

Step-by-step explanation:

Given: BD bisects $\angle ABC$

$\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}$

To find: $\angle ABC$

Solution:

A bisector of an angle divides it into angles of equal measures.

As BD bisects $\angle ABC$ , $\angle ABD=\angle DBC$

Put $\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}$

$\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}$

So,

$\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}$

$\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}$

Answer:

You should circle:

15, 17, 19, 24, 25, 26, 28

Step-by-step explanation:

The values x that falls within 1 standard deviation of the mean are those which.

$|x - 20.4| \leq 7.9$

|6 - 20.4| = 14.4 > 7.9

6 is not within 1 standard deviation of the mean.

|11 - 20.4| = 9.4 > 7.9

11 is not within 1 standard deviation of the mean.

|15 - 20.4| = 5.4 < 7.9

15 is within 1 standard deviation of the mean.

|17 - 20.4| = 3.4 < 7.9

17 is within 1 standard deviation of the mean.

|19 - 20.4| = 1.4 < 7.9

19 is within 1 standard deviation of the mean.

|24 - 20.4| = 3.6 < 7.9

24 is within 1 standard deviation of the mean.

|25 - 20.4| = 4.6 < 7.9

25 is within 1 standard deviation of the mean.

|26 - 20.4| = 5.6 < 7.9

26 is within 1 standard deviation of the mean.

|28 - 20.4| = 7.6 < 7.9

28 is within 1 standard deviation of the mean.

|33 - 20.4| = 12.6 > 7.9

33 is not within 1 standard deviation of the mean.
