H(x)=x²-5 Find h(-7)

Mathematics
2 answers:
anastassius [24]2 years ago

Answer:

h (-7) = 44

Step-by-step explanation:

when working with a function, when we place a value, replacing x, in parentheses next to the function, we are to find the function by replacing x with that value.

Essentially, we need to replace x with -7. [replace meaning substitute]

h (x) = x² - 5

h (-7) = (-7)² - 5

h (-7) = 49 - 5

h (-7) = 44

so, h (-7) = 44

note: ² means to square a number (to multiply that number by itself)

(-7)² ->  - 7  ·  - 7 = 49

----

hope this helps!!

Answer:

h(x) = 44

Step-by-step explanation:

h(x) = x² - 5, h(-7) means x = -7

h(x) = (-7)² - 5

h(x) = 49 - 5

h(x) = 44

The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values

a) The equation of the least-squares regression line is \underline {\hat y = 235 \cdot x + 10835}

b) The correlation coefficient for the sample is approximately 0.351

c) The slope gives the increase in the attendance per increase in wins

Reasons:

a) From the computer regression output, we have;

The y-intercept and the slope are given in the <em>Coef</em> column

The y-intercept = 10835

The slope = 235

The equation of the least-squares regression line is therefore

\underline {\hat y = 235 \cdot x + 10835}

b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229

Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351

The correlation coefficient for the sample, r ≈ <u>0.351</u>

c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins

How many ways are there to select 25 books from a collection of 27 books? i am just studying today
laiz [17]

notice, this will just be a Permutation.

\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad \stackrel{\textit{25 books off a total of 27}}{_{27}P_{25}=\cfrac{27!}{(27-25)!}} \\\\\\ _{27}P_{25}=\cfrac{27!}{2!}\implies 5444434725209176080384000000
