### Answers

**Answer:**

R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

**Step-by-step explanation:**

Squaring both sides of equation:

I^2 = (ER)^2/(R^2 + (WL)^2)

<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)

<=>(ER)^2 - (IR)^2 = (IWL)^2

<=> R^2(E^2 - I^2) = (IWL)^2

<=> R^2 = (IWL)^2/(E^2 - I^2)

<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

### Answers

**Answer:**

**Step-by-step explanation:**

y=mx+b, equation for slope-intercept line

we can work out the equation based on given two points (1,1) and (7,4)

m=(y2-y1)/(x2-x1)= (4-1)/(7-1)= 3/6= **1/2**

y=**1/2**x+b

For (1,1)

1= 1/2+b ⇒ **b= 1/2**

For (7,4)

4=7*1/2+b ⇒ **b= 1/2**

So we get

**y= 1/2x+1/2**

On a road trip you see a sign "350 km to Indianapolis". About how many hours will it

take you to drive to Indianapolis if you are traveling at 68 mi/h (1 mile 1.61 km).

Round your answer to the nearest hundredth.

### Answers

**Answer: ** 3.20 hours

**Step-by-step explanation:**

Hi, to answer this question, first we have to convert the kilometers into miles:

Since: 1 mile = 1.61 km

For 350km:

350 /1.61 = 217.39 miles

Next, we have to apply the next formula:

Time = distance / speed rate

Replacing with the values given:

Time = 217.39 mi / 68 mi/h = 3.20 hours

### Answers

**Answer:**

**Option D. 10,779 feet**

**Step-by-step explanation:**

Given from the figure attached,

PT = OB = 7000 ft

PB = OT = x feet

and angle of elevation (∠POT) = 30°

By applying Tan rule in the triangle POT,

tan33° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex] = [tex]\frac{PT}{OT}[/tex]

tan33° = [tex]\frac{7000}{x}[/tex]

x = [tex]\frac{7000}{\text{tan}33}[/tex]

x = 10779 feet

Therefore, distance between the bird (B) and plane (P) is 10,779 feet.

**Option D. will be the answer.**

Sue rolls a die twice. What is the probability as a fraction that she will get a three both times?

### Answers

**Answer:**

P = [tex]\frac{1}{36}[/tex]

**Step-by-step explanation:**

The probability of rolling a 3 on the first and second try is: [tex]\frac{1}{6}[/tex]

To get the probability of rolling a 3 both times is [tex]\frac{1}{6} *\frac{1}{6} = \frac{1}{36}[/tex]

The chance she rolls a 3 both times is [tex]\frac{1}{36}[/tex]

**Step-by-step explanation: **In this problem, we're given that a number cube is rolled twice and we're asked to find the probability or rolling a 3 and a 3.

It's important to understand that the two rolls of the number cube are independent events because the results of one role does not affect the results of the other roll. To find the probability of two independent events, we first find the probability of each event, then we **multiply** the probabilities.

So let's first find the probability of rolling a 6 with our first role of the number cube. Remember that we can find the probability of an event using the ratio number of favorable outcomes over total number of outcomes. Since there's only one way to roll a six and there are six possible outcomes 1 2 3 4 5 and 6, the probability of rolling a 6 is 1/6.

1/6 will also be the probability for the second role.

Now multiply 1/6 x 1/6 to get 1/36.

So, 1/36 is your answer.

Given that 2 x − 9 y = 22 Find y when x = 7

### Answers

**Answer:**

**y = (-8)/9**

**Step-by-step explanation:**

Solve for y:

14 - 9 y = 22

Subtract 14 from both sides:

(14 - 14) - 9 y = 22 - 14

14 - 14 = 0:

-9 y = 22 - 14

22 - 14 = 8:

-9 y = 8

Divide both sides of -9 y = 8 by -9:

(-9 y)/(-9) = 8/(-9)

(-9)/(-9) = 1:

y = 8/(-9)

Multiply numerator and denominator of 8/(-9) by -1:

Answer: y = (-8)/9

**Answer:**

-8/9

**Step-by-step explanation:**

2 x − 9 y = 22

x=7

2*7-9y=2214-9y=229y=14-229y=-8**y= -8/9**

t / 2 pi = sqrt(m/k)

Square each side

(t / 2 pi )^2= (sqrt(m/k))^2

### Answers

**Answer:**

**D: Undefined**

**Step-by-step explanation:**

You can use the unit circle or your calc for this (don't forget to put it in radians!). I will use the unit circle to explain.

Tangent on the unit circle is on the xy lines themselves. tan (π/2) would be on the positive y axis. Remember that tan∅ is *sin∅/cos∅* and that the unit circle's radius is **always** one. If that is the case, the coordinate for tan (π/2) would be (0, 1). If cos is always x and sin is always y, you plug it in for tan∅. The fraction 1/0 is undefined, since you can't divide anything by 0. Therefore, tan (π/2) is **undefined**.

The line passing through points(2,4) parallel to line who’s equation is Y equals X

### Answers

Answer:

The equation of that line is y = x + 2

Step-by-step explanation:

Here, we want to write the equation of the line that passes through the point given.

Now for the line which is our reference, we have the equation as;

y = x

Comparing this with the general equation of a straight line which is y = mx + c

where m is the slope, we can clearly see that the slope of that line is 1

Now if two lines are parallel, that surely do have equal slopes.

This means that the line that passes through that point also have a slope of 1

So we want to find the equation of a line with slope 1 and passing through the point (2,4)

What we use here is the point-slope form

Mathematically, that is

y-y1 = m(x-x1)

where (x1,y1) here is (2,4)

Thus, the equation of the line would be;

y-4 = 1(x-2)

y-4 = x-2

y = x-2+ 4

y = x+ 2

Explain why the initial value of any function in the form of F(x)=a(b^x) is equal to a

### Answers

**Step-by-step explanation:**

We have a function in the form

[tex]f(x)=a(b^x)[/tex]

The initial value of a function refers to the value of the function when x=0.

If we plug in x=0 into our function, we get

[tex]f(x)=a(b^x)\\\\f(0)=a(b^0)[/tex]

Any number to the power of 0 is equal to 1, so we can rewrite this function as

[tex]f(0)=a(1)\\\\f(0)=a[/tex]

Here we can see that we have just shown why the initial value of any function in the the given form is equal to a.
