Find the measure of angle 1

For this case we have two functions of the form y = f (x). We must find the quotient of the following functions:

[tex]f (x) = x + 2\\g (x) = 3x + 5[/tex]

So, we have by definition:

[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]

Answer:

[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]

with 3x + 5 different from zero, so that the function is defined

Answer:

[tex]\frac{f(x)}{g(x)}=\frac{x+2}{3x+5}[/tex]

where [tex]x\ne -\frac{5}{3}[/tex]

Step-by-step explanation:

The given functions are:

f(x) = x + 2 and g(x) = 3x + 5

[tex]\frac{f(x)}{g(x)}=\frac{x+2}{3x+5}[/tex]

Since this is a rational function, the function will not be defined where denominator equals zero.

We need to restrict the function or define the domain.

This is a rational function defined for [tex]x\ne -\frac{5}{3}[/tex]

Answer:

Option B. Linear

[tex]y=4x+18[/tex]

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

so

[tex]y=mx+b[/tex]

In this problem

[tex]m=4\frac{in}{h}[/tex]

[tex]b=18\ in[/tex] ----> the y-intercept

substitute

[tex]y=4x+18[/tex]

Question:

A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. Which type of functions best models this situation?

A) exponential

B) linear

C) quadratic

D) radical

Answer & Step-by-step explanation:

It is given that a ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour.

If a function has constant rate of change, then the it is a linear function.

It the given case the rate of change is constant so linear function best model this situation.

The slope intercept form of linear function is

f(x)=mx+b           ... (1)

where, m is slope and b is y-intercept or initial value.

Ski resort has 18 inches of snow on the ground it means initial value is 18.

The snow is falling at a rate of 4 inches per hour. So, m=4.

Substitute m=4 and b=18 in equation (1).

f(x)=4x+18

Therefore Linear decreasing function best model this situation and the required function is f(x)=4x+18.

Step-by-step explanation:

Answer: 4.47 seconds.

Step-by-step explanation:

Hi, the rock will reach the river when the height (h) is 0.

So, replacing in the equation given:

h= -16t2+320

Where t is the time  

0= -16t2+320

Solving for t

-320 = -16t2

-320/-16 =t2

20 = t2

√20 =t

4.47 = t

Assuming that t is the time in seconds, the rock will reach the river after 4.47 seconds.

Step-by-step explanation:

We can break  this figure into two rectangles.

One rectangle is a vertical triangle that is 3 yd across by 7 yds down

The area of this figure is

A = lw

   = 3 * 7 = 21

The other rectangle is 1 yd across and by 2 yds down  

The area of this figure is

Step-by-step explanation:

Claim: FICO credit scores are greater than 675

Thus, x = 675

We are given:

Sample size = n = 50

Sample Mean = u = 719

Sample Standard deviation = s = 92

The formula to find the t-statistic is:

[tex]t=\frac{x-u}{\frac{s}{\sqrt{n} } }[/tex]

Using the above values, we get:

Answer:

c=3

Step-by-step explanation:

We have 2 points, we can find the slope using

m = (y2-y1)/(x2-x1)

Substituting into this equation

-1/4 = (4-5)/(7-c)

-1/4 = -1/(7-c)

Multiply both sides by -1

1/4 = 1/(7-c)

The denominators have to be the same

4 = 7-c

Subtract 7 from each side

4-7 = 7-7-c

-3 = -c

Multiply by -1

3 =c

Simplify brackets

10x - 4 = 8x + 14

Add 4 to both sides

10x = 8x + 14 + 4

Simplify 8x + 14 + 4 to 8x + 18

10x = 8x + 18

Subtract 8x from both sides

10x - 8x = 18

Simplify 10x - 8x to 2x

2x = 18

Divide both sides by 2

x = 18/2

Simplify 18/2 to 9

x = 9

10x - 4 = 8x + 14

Step 1: Combine like terms

x's go with x's (10x and 8x). To do this subtract 8x to both sides

(10x - 8x) - 4 = (8x-8x) + 14

2x - 4 = 14

Normal numbers go with normal numbers (-4 and 14). To do this add 4 to both sides

2x + (-4 + 4) = 14 + 4

2x = 18

Step 2: Isolate x by dividing 2 to both sides

2x/2 = 18/2

x = 9

Option C will have greatest number of permutations.

Step-by-step explanation:

A.

The number of license plates with 4 letters followed by 3 numbers, where letters and digits cannot be repeated.

We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter

25 letters options for 2nd letter

24 letter options for 3rd letter

23 letter options for 4th letter.

So total options for 4 letters 26*25*24*23 = 358800

Now, 3 numbers are required. We have total 10 numbers (0-9)

10 number options for 1st number

9 number options for 2nd number

8 number options for 3rd number

Total options for 3 numbers= 10*9*8 = 720

total options for 4 letters and 3 numbers will be: 358800 * 720 = 258,336,000

B.

The number of license plates with 3 letters followed by 4 numbers, where letters and digits cannot be repeated.

We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter

25 letters options for 2nd letter

24 letter options for 3rd letter

So total options for 3 letters= 26*25*24 = 15600

Now, 4 numbers are required. We have total 10 numbers (0-9)

10 number options for 1st number

9 number options for 2nd number

8 number options for 3rd number

7 number options for 4th number

Total options for 4 numbers = 10*9*8*7 = 5040

total options for 4 letters and 3 numbers will be: 15600 * 5040 = 78,624,000

C. The number of license plates with 4 letters followed by 3 numbers, where letters and digits can be repeated.

Now, the letters and digits can be repeated. So we have 26 options for each 4 letters and 10 options for each 3 numbers

26*26*26*26 *10*10*10 = 456,976 * 10,00 = 456,976,000

total options for 4 letters and 3 numbers will be: 456,976,000

D.

The number of license plates with 3 letters followed by 4 numbers, where letters and digits can be repeated.

Now, the letters and digits can be repeated. So we have 26 options for each 3 letters and 10 options for each 4 numbers

26*26*26 *10*10*10*10 = 17,576 * 10,000 = 175,760,000

total options for 3 letters and 4 numbers will be: 175,760,000

So, Option C will have greatest number of permutations.

The angle that is congruent to angle 1 is angle 4 (m∠ 4).

What is congruent angle?

Congruent angles are angles that have the same measure in degrees or radians. So, if two angles are congruent, it means that they are equal in size.

From the diagram of the parallel lines, the angle that is all congruent to angle 1 include;

m∠ 1 = m∠ 4 (vertically opposite angles are equal)

m∠ 2 = m∠ 5 (vertically opposite angles)

m∠ 3  = m∠ 6 (vertically opposite angles)

So m∠ 1 = m∠ 4

Thus, the angle that is congruent to angle 1 is angle 4.

x²+y²-4y-46=0

Step-by-step explanation:

the equation of a circle is in the form (x - a)² + (y - b)² = r², where (a,b) is the center of the circle

the equation is (x - 0)² + (y - 2)² = r², where r is the radius. But r is the distance from (0,2) to (7,3)

the distance from two points is given by r² = (x₁ -x₂)² + (y₁ - y₂)²

r²= (0 - 7)² + (2 - 3)²

r² = 49 + 1 = 50

hence the equation is  

                  (x)² + (y - 2)² = 50

                  x²+y²-4y+4 = 50
