Answer:

m<BDC = 62 degrees

Step-by-step explanation:

Using the expression;

<ABC = <ABD + <DBC

107 = 7x-4 + 9x - 1

107 = 16x-5

16x = 107 + 5

16x = 112

x = 112/16

x = 7

Get m<DBC

m<BDC = 9x - 1

m<BDC = 9(7)-1

m<BDC = 63 - 1

m<BDC = 62 degrees

Answer:

  b.  9 inches

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Solving for h, we get ...

  h = 2A/b

  h = 2(36 in²)/(8 in) = 72/8 in

  h = 9 in

The height of the triangle is 9 inches.

Answer:

Dec 10

Step-by-step explanation:

0.25 liter = 250 ml

4 ml * 3 = 12 ml

250/12 = 20.83 days

Nov 20 - Nov 30: 11 days

Dec 1 - Dec 9: 9 days

On December 9, she can still take her 3 doses.

By December 9, she will have taken 12 ml per day for 20 days for a total of 240 ml. She has 10 ml left for Dec 10th.

On Dec 10, she will take 2 doses of 4 ml and 1 dose of 2 ml, and she will finish the medicine.

Answer:

4x² - 2x + 5

Step-by-step explanation:

5x² - 1x² = 4x²

8x - 6x = 2x

2 + 3 = 5

= 4x² - 2x + 5

To write an equation for this line, you first need to understand how to derive it.

Let's utilize slope-intercept form, as it's the easiest to understand compared to any other form for line functions:

y = mx + b

m: The slope of the line

b: The y-intercept (The point where the line is at the y-axis)

Now that we've defined our variables, how do we go about making the actual equation? Let's start off with the slope, m.

The slope is a measure of how high or low the line is. The number is a ratio between the rise and run of a slope. In other words, it is essentially [tex]\frac{rise}{run}[/tex]

Let's look back at the graph. In the time interval from 1 to 2 seconds, we see that the line rises by 22 feet. Because the time interval is only 1 second, the run is 1 second.

Therefore:

m = [tex]\frac{rise}{run}[/tex]

m = [tex]\frac{22}{1}[/tex]

m = 22

We now have the first variable of the equation.

y = 22x + b

What about b? As we established earlier, b is the value of coordinate y at the y-intercept. Essentially, to find b we need to know what the value of y is when the coordinate x is 0.

As you can see from the graph you made, the value of y when x is 0 is also 0. This makes sense, too. How can the cheetah travel distance at 0 seconds when it obviously hasn't started moving? We now know b = 0. Now, we have gotten all of the variables we need to make a full equation:

y = 22x + 0

y = 22x

If you'd like me to explain how I did anything, just ask!

Answer:

Equation: y=22x + 0 (you can put 0 if you want)

Step-by-step explanation:

Okay, so this is set up as a y=mx+b equation meaning that m=rate of change and b=y-intercept. If a cheetah runs 22 feet per second which is x, that means that m=22. And if 1 second is equal to 22 feet then in 0 seconds they run 0 feet, which is your y-intercept. Another way to find the rate of change (m) is by using the equation y2-y1/x2-x1 or 44-22/1 in this case. This equation is usually written as y=22x.  Hope this helps!

Answer: 6x-15

Step-by-step explanation: 3 times 2x equals 6x and 3 times -5 equals 15, which makes 6x-15

Answer:

6x-15

Step-by-step explanation:

Distributive property means that you would be distributing.

So, 3 · 2x = 6x

3 · -5 = -15

You cannot simplify any further, so the final answer is 6x - 15.

Answer:

  178.6 ft

Step-by-step explanation:

The definitions of the trig functions tell you ...

  Cos = Adjacent/Hypotenuse

  cos(69°) = FD/DE

  DE = FD/cos(69°) ≈ (64 ft)/0.3584

  DE ≈ 178.6 ft

Answer:

The degrees of freedom is 6 for the chi square independence test.

Step-by-step explanation:

This is test hypothesis of independence. The test statistic under H0 is

χ²= ∑ (O - E)²/ E

where O is the observed and E is the expected frequency

which  has an approximate chi square distribution with ( r-1) (c-1) degrees of freedom, where r= rows and c= columns.

Here there are 4 rows and 3 columns

Hence the degrees of freedom will be

( 4-1) ( 3-1)= 3*2= 6
