The transformation of the graphs is

1st graph is (x,y)→(x-4,y+2)

2nd graph is (x,y)→(x+6,y+0)

Given that,

There are two graphs with 2 triangles in each graph.

We have to find the transformation of the graphs.

Take the 1st graph,

We have 2 triangles ABC and A'B'C'.

The points are,

A=(0,0), B=(3,-4) and C=(-1,-2)

A'=(-4,2), B'=(1,-2) and C'=(-5,0)

We get the transformation as

(x,y)→(x-4,y+2)

Check the A and A' points

The A terms goes left for 4 times to A' so we take x-4 and the A terms goes up for 2 times to A' so we take y+2.

Similarly,

The B terms goes left for 4 times to B' so we take x-4 and the B terms goes up for 2 times to B' so we take y+2.

Similarly,

The C terms goes left for 4 times to C' so we take x-4 and the C terms goes up for 2 times to C' so we take y+2.

Now the 2nd graph,

We have triangle FCP and F'C'P'

The points are,

F=(-5,5), C=(-2,5) and P=(-3,0)

F'=(1,5), C'=(4,5) and P'=(3,0)

We get the transformation as

(x,y)→(x+6,y+0)

Check the F and F' points

The F terms goes right for 6 times to F' so we take x+6 and the F terms remain same so we take y+0

Similarly,

The C terms goes right for 6 times to C' so we take x+6 and the C terms remain same so we take y+0

Similarly,

The P terms goes right for 6 times to P' so we take x+6 and the P terms remain same so we take y+0

Therefore, The transformation of the graphs is

1st graph is (x,y)→(x-4,y+2)

2nd graph is (x,y)→(x+6,y+0)

I talked to my professional tutor about this, she didn’t happen to explain the answer though. She’s been working as a teacher for 20 years.

The probability that exactly 3 automobiles fail the test is 0.01733.

The probability that fewer than 3 of the automobiles fail the test is

0.9803.

Complete question:

Car inspection of all the registered automobiles in Colorado, 5% fail the state emissions test. Twelve Automobiles are selected at random to undergo an emissions test. Round the answers to at least four decimal places

(a) Find the probability that exactly three of them fail the test.

(b) Find the probability that fewer than three of them fail the test.

What is Binomial Distribution?

The probability of success is said to follow a binomial distribution when many similar and independent Bernoulli trials are conducted. The likelihood of success and the quantity of tries are its dimensions. For every trial, the chance of success is the same.

State emission test failure probability is 0.05.

12 vehicles total are present.

Let's look at failing the test as a victory. If success is represented by p, then p = 0.05.

Considering that n represents the number of cars, n equals 12.

Let X represent how many vehicles fail the test.

So, X ∼ Bin (8,0.05)

P(X=x)= [tex]^{n}C_{x}p^{x}(1-p)^{n-x}[/tex]

         = [tex]^{12}C_{x}0.05^{x}(0.95)^{12-x}[/tex]

a) Probability that exactly 3 automobiles fail the test is given by,

  P(X=3)= [tex]^{12}C_{3}0.05^{3}(0.95)^{12-3}[/tex]

             =0.01733

So, the probability that exactly 3 automobiles fail the test is 0.01733.

b) Probability that fewer of them than 3 fail the test is given by,

P(X<3)= P(X≤2)

         = P(X=0)+P(X=1)+P(X=2)

         =  [tex]^{12}C_{0}(0.05)^{0}(0.95)^{12}[/tex] + [tex]^{12}C_{1}(0.05)^{1}(0.95)^{11}[/tex]+[tex]^{12}C_{2}(0.05)^{2}(0.95)^{10}[/tex]

         = 0.9803

Hence, the probability that fewer than 3 of the automobiles fail the test is

0.9803.

Answer:

x = 3

Step-by-step explanation:

15x + 8 and 9x + 26 are corresponding angles and are congruent , then

15x + 8 = 9x + 26 ( subtract 9x from both sides )

6x + 8 = 26 ( subtract 8 from both sides )

6x = 18 ( divide both sides by 6 )

x = 3

The answer of 11/3*7/3*5/3 after multiplication is 385/27.

According to the question,

We have the following expression:

11/3*7/3*5/3

We know that when we multiply two more than two fractions then numerator is multiplied into the numerator and the denominator is multiplied into the denominator of another fraction.

So, we have the following expression after multiplying first two fractions:

77/9*5/3

Now, again repeating the above step:

385/27

(This can not be further classified into the simplest form because the numerator and denominator of this fraction can not be divided by one number.)

Hence, the answer of 11/3*7/3*5/3 after multiplication is 385/27.

For the given triangle ABC, Measures of given angles are m∠A=30 , m∠C=90 , m∠B=60 and side AC = 28 then the measure of side                   AB = 56√3/3 , BC =28√3/3.

As given in the question,

In the triangle ABC,

Measures of given angles are :

m∠A=30 , m∠C=90 , m∠B=60

And Measure of side AC = 28

As ABC is right angled triangle with m∠C=90,

If we take ∠A,

AC = Base

AB = Hypotenuse

BC = perpendicular side

Using trigonometric ratios,

tan A = BC/AC

⇒tan 30° = BC / 28

⇒1/√3 = BC /28

⇒ BC = 28/√3

⇒BC = 28√3/3

Now,

cos A = AC/AB

⇒ cos 30° = 28/AB

⇒ √3/2 = 28 /AB

⇒ AB = (28 × 2)/√3

⇒ AB = 56√3/3

Therefore, for the given triangle ABC, Measures of given angles are m∠A=30 , m∠C=90 , m∠B=60 and side AC = 28 then the measure of side AB = 56√3/3 , BC =28√3/3.

m = (-1/2); (2, -5)

                 (x₁, y₁)

y - y₁ = m(x - x₁)

y - (-5) = (-1/2)(x - 2)

y + 5 = (-1/2)x + 1

    -5               -5

----------------------------

y = (-1/2)x - 4

I hope this helps!

Step-by-step explanation:

the slope-intercept form is

y = ax + b

"a" being the slope, "b" being the y-intercept (the y- value when x = 0).

the slope is the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.

a perpendicular slope simply turns the original slope upside-down with x and y, and it flips the sign.

the slope of the origins line is 2 = 2/1.

the perpendicular slope is -1/2.

so, the equation looks like

y = -1/2 x + b

to get b we use the point coordinates :

-5 = -1/2 × 2 + b = -1 + b

-4 = b

so, the full equation is

y = -1/2 x - 4

The value of t from the given derivative is 7.38.... or −7.38....

The given second order derivative is r''(t)=2/t².

The process of finding derivatives of a function is called differentiation in calculus. A derivative is the rate of change of a function with respect to another quantity.

Here, r''(t)=2/t²

The anti-derivative is

Set the function up in integral form and evaluate to find the integral.

r'(t) = -2/t

Now, 3=-2/t

⇒ t=-2/3

Set the function up in integral form and evaluate to find the integral.

r(t)=-2ln(|t|)

So, -4=-2ln(|t|)

The monthly deposit required to save up to $625,357.24 (future value) in 40 years at a 7.2% APR is $225.20.

The monthly deposits are the periodic savings that the investor must make to achieve future value.

The monthly deposit is compounded at the monthly annual percentage rate (APR).

We can compute the required monthly deposits using an online finance calculator as follows:

N (# of periods) = 480 months (40 years x 12)

I/Y (Interest per year) = 7.2%

PV (Present Value) = $0

FV (Future Value) = $625,357.24

Results:

Monthly Deposits (PMT) = $225.20

Sum of all periodic payments = $108,096 ($225.20 x 480)

Total Interest = $517,261.24
