Find the value of x <br><br> A. 5 square root 2/2<br> B 5<br> C 10<br> D 10 square root 2
grandymaker [24]

Answer:

The answer is C

Step-by-step explanation:

That side with the 5 is equal to 7.071067812.... (irrational number)

To get x you need to use the equation a^2 + b^2 = c^2

A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.

7.071037812.... ^2 is 50

Now your equation would be 50+50= c^2 (which is the same as x^2)

100= c^2 is simplified by finding the square root of 100.

Your answer is 10 for side X because the square root of 100 is 10.

This problem was solved using the Pythagorean Theorem.

A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a fu
den301095 [7]

Answer:

y =120*1.1^x

r = 10\% --- Percentage increase

Step-by-step explanation:

Given

Let

x \to months

y \to mice

So, we have:

(x_1,y_1) = (0,120) --- Monday

(x_2,y_2) = (1,132) --- One month later

Required

The function

The function is represented as:

y = ab^x

In (x_1,y_1) = (0,120), we have:

120 =a * 1

120 =a

Rewrite as:

a = 120

In (x_2,y_2) = (1,132), we have:

132 = a * b^1

132 = a * b

Substitute a = 120

132 = 120 * b

Solve for b

b = \frac{132}{120}

b = 1.1

Recall that:

y = ab^x

Hence, the function is:

y =120*1.1^x

To get the monthly percentage increase (r), we have:

y = a(1 + r)^x

Compare to: y = ab^x

So:

1+r =b

Make r the subject

r = b-1

r = 1.1-1

r = 0.1

Express as percentage

r = 0.1*100\%

r = 10\%

How do you find the slope of the points: (19,-16),(-7,-15)?
nirvana33 [79]

Answer:

\Huge\boxed{\mathsf{\frac{1}{26} }}

Step-by-step explanation:

<em><u>SLOPE FORMULA:</u></em>

\longrightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1} }}

Y₂=(-15)

Y₁=(-16)

X₂=(-7)

X₁=19

Solve.

\displaystyle \mathsf{\frac{(-15)-(-16)}{(-7)-19}=\frac{(-15)+16}{(-7)-19}=\frac{1}{-26}=\boxed{\mathsf{\frac{1}{26}} }   }}}}

So, the slope is 1/26.

Two chains of clothing stores, Impulse Clothing and Opal Essence, were founded in the same year, although some outlets of Opal E
kvasek [131]

By combining the equations we can found that the number of impulse clothing and Opal essence stores by equations be C (3x+5)/2 where x is the number of years after the brand's founding.

Given The equation showing number of impulse clothing stores is C=2x. The equation showing number of clothing stores be C=x+5.

We have to first plot both the equations on the graph.

For plotting we need points which can be calculated as

C=2x

when x=1 ,C or y=2

when x=3 , C or y=6

C=x+5

when x=0 ,C or y=5

when x=1 ,C or y=6

By combining both equations we get

C=(3x+5)/2

Plot this also and finding points

when x=0  , C=5/2

when x=1 , C=4

Hence the combination of both statements which shows the total stores owned is C=(3x+5)/2
