Answer:

3[tex]\sqrt{7}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] = [tex]\sqrt{ab}[/tex] , then

[tex]\sqrt{63}[/tex]

= [tex]\sqrt{9(7)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{7}[/tex]

= 3[tex]\sqrt{7}[/tex]

2) <3 and <4 are complementary angles. If m<23 = (x + 24)° and m<4 =(x)º, then
find the measures of these angles.

Answers

Answer:

angle 3: 57; angle 4: 33

Step-by-step explanation:

because they are complementary angles they add up to 90 so we set the equation up like this

x + 24 + x = 90

after combining like terms and subtracting 24 from each side you get this

2x = 66

when you simply you get this

x = 33

angle 3 is 57 when we add and angle 4 is 33

How to find a base of a something without area

PLEASE HELP ME

Answers

Answer:  Measure the length of the base. Call this value "b." Substitute these values into the equation for the area of a triangle: area = 1/2bh

Step-by-step explanation:

In geometry, the bottom of a three-dimensional object is called a base – if the top of the solid is parallel to the bottom it is also called a base. Since bases occupy a single plane, they have only two dimensions. You can find the area of a base by using the formula for the area of that shape.

Answer:

area of trapezium =1/2(a+b)*h

=1/2(7+10.4)*6.7

=1/2(17.4)*6.7

=1/2(116.58)

=116.58/2

=58.29 square cm

Answer:

58.29 cm²

Step-by-step explanation:

Hi there!

Area of a trapezoid: [tex]A=\displaystyle \frac{a+b}{2} *h[/tex]

We're given that a = 7, b = 10.4 and h = 6.7. Plug these into the above:

[tex]A=\displaystyle \frac{7+10.4}{2} *6.7\\\\A=\displaystyle \frac{17.4}{2} *6.7\\A=8.7*6.7\\A=58.29[/tex]

Therefore, the area of the trapezoid is 58.29 cm².

if a domain is "all real numbers" can it be a function?

Answers

Hello!

Answer:

Yes

Step-by-step explanation:

Functions assign outputs to inputs. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Hope this helps!

Answer:

Yeah

Step-by-step explanation:

you know real numbers are the combination of. the rational and irrational number so they domain over all other functions

The scatterplot above shows the number of wins and the attendance per game for 30 baseball teams in 2017.

Also shown are the least-squares regression line and computer output.

a) Using the information above, what is the equation of the least-squares regression line?

b) What is the value of the correlation coefficient for the sample?

c) Interpret the slope of the least-squares regression line in context.

Answers

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 [tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]

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 Coef column

The y-intercept = 10835

The slope = 235

The equation of the least-squares regression line is therefore

[tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]

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 ≈ 0.351

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

Answer:

if x = -2, y = -10

if x = 0, y = -4

if y = -1, x = 1

Step-by-step explanation:

if x = -2:

f(-2) = -6 - 4

f(-2) = -10

if x = 0:

f(0) = 3(0) - 4

Which equation has no solution?
Group of answer choices

the absolute value of 2 x minus 1 equals 0

the absolute value of 5 minus 3 x equals negative 8

the absolute value of negative x minus 3 equals 5

the absolute value of negative x plus 9 equals 0

Answers

Answer:

B. the absolute value of 5 minus 3 x equals negative 8

Step-by-step explanation:

The absolute value is never negative as per definition.

A. |2x - 1| = 0, has solutionB. |5 - 3x| = - 8, no solutionC. |-x - 3| = 5, has solutionD. |-x + 9| = 0, has solution

Correct choice is B

Given :-

the absolute value of 2 x minus 1 equals 0the absolute value of 5 minus 3 x equals negative 8the absolute value of negative x minus 3 equals 5the absolute value of negative x plus 9 equals 0

To find :-

Which of the equation has no solution .

Answer :-

Convert the given statement from word form to mathematical form ,

| 2x - 1| = 0 | 5 - 3x | = -8 | -x-3 | = 5 | - x + 9| = 9

As we know that the modulus function always gives positive values . So from the given options we can see that |5-3x| = -8 , which is not possible .

Hence | 5-3x | = -8 has no solutions .
