In triangle ABC, angle bisectors line AD, line BE, and line CF meet at I. If DI = 3, BD = 4, and BI = 5, then compute the area of triangle ABC

Answers

Answer 1

The area of triangle ABC is the amount of space on the triangle

The area of the triangle is 54.84 square units

How to determine the area of triangle ABC

Start by drawing the triangle (see attachment)

Next, calculate the measure of angle B using the following tangent ratio

[tex]\tan(B/2) = \frac 34[/tex]

This gives

[tex]\tan(B/2) = 0.75[/tex]

Take the arc tan of both sides

[tex]B/2 = 36.87[/tex]

Multiply by 2

[tex]B = 73.74[/tex]

Next, calculate the length of side AD using the following equation

[tex]AD = \tan(B) * BD[/tex]

This gives

[tex]AD = \tan(73.74) * 4[/tex]

[tex]AD =13.71[/tex]

The area of the triangle is then calculated as:

[tex]Area = AD * BD[/tex]

This gives

[tex]Area = 13.71 * 4[/tex]

[tex]Area = 54.84[/tex]

Hence, the area of the triangle is 54.84 square units

Solve by using the zero product property to solve y = x^2-4x-21 for its zeroes?
Explain in a short paragraph.

Answers

Answer:

  x = -3 or 7

Step-by-step explanation:

The zero product property tells you a product will be zero if and only if a factor is zero. This property is used to find the zeros of polynomial functions by factoring them, then considering the variable values that make the factors zero. The zero of a monic linear binomial factor will be the opposite of the constant in that binomial.

__

The factored form of the given polynomial is ...

  y = (x -7)(x +3)

The values of x that make these factors zero are ...

  x -7 = 0   ⇒   x = 7

  x +3 = 0   ⇒   x = -3

The zeros of the polynomial function are x = -3, and x = 7.

An exponential function is a function that grows exponentially.

Exponential functions have a multiplicative rate of change. This means each term can be multiplied by a specific number to get to the next.

Example of an exponential function:

1, 2, 4, 8, 16, 32, 64, 128, 256...

Knowing this, let's look at each example.

A.

The rocket grows at a rate of 45 m/s, but then goes back down. This is not an exponential function. This is most likely a quadratic function.

B.

Each term is being multiplied by 4. This is correct.

C.

This is too vague. We cannot determine what this is.

D.

This is a linear function. It has an additive rate of change; not a multiplicative one. This is wrong.

E.

Each term is 50% of the previous one. This is correct.

F.

The population is multiplied by 2 each month. This is correct.

Answer:

2, 5, 6

Tweets: Exponential function  (quadruples each time)

hii the lateral surface area of a cube is 256 m cube . find the volume of the cube

Answers

Answer:

512cm3

Step-by-step explanation:

A lateral surface area of a cube is 256 m2. Find its volume.

A cube is a three-dimensional shape that is made up of 6 congruent square faces.

Answer: If the lateral surface area of a cube is 256 m2, then its volume is 512 cubic meters.

The lateral area of a cube is the sum of areas of all side faces of the cube

Explanation:

The lateral surface area (LSA) of the cube = sum of areas of all 4 side faces.

Let the edge length of the cube be x.

LSA = x2 + x2 + x2 + x2 = 4x2

Given that, LSA of the cube is 256 m2

4x2 = 256

x2 = 256/4

x2 = 64

x = 8

Length of edge of the given cube is 8 m.

The volume of a cube is x3.

The volume of cube = x3 = 83 = 512 m3

Thus, the volume of the given cube is 512 m3.

The volume of the given cube is 512 m³.

What is volume of cube?

The volume of a cube is defined as the total number of cubic units occupied by the cube completely. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.

Given that, the lateral surface area of a cube is 256 m cube.

We know that, the formula to find lateral surface area of a cube is 4a², where a is edge of a cube

Now, 4a²=256

a²=64

a=8 m

The formula to find the volume of a cube is a³, where a is edge of a cube.

Thus, volume of a cube =8³ =512 m³

Therefore, the volume of a cube is 512 m³.

The average natural gas bill for a random sample of 26 homes in the 19808 zip code during the month of March was $305.30 with a sample standard deviation of $46.50. The 80% confidence interval around this sample mean is ________.

Answers

Given Confidence interval is 80% and we are only using 1 sample.
First find degrees of freedom = sample size - 1
Or: df = 26-1 = 25
Now subtract confidence int by 1 and divide by two to make it two tailed. Remember normal distribution looks bell-shaped and we are only looking on one side for our CI.
So: (1-0.8)/2= 0.2/2=0.1 which is our alpha
Now we need to use T-distribution table that should be found in textbook or online.
For 25 df and an alpha of 0.1 I get 1.316.
Some t-dist tables will even have the confidence intervals given DF on the bottom.
Now we have to divide sample Standard deviation by sample size to find the Standard error. This basically is to look for SD of all sample means around population mean, but more on that can be found online.
So: se= 46.5/sqrt(26)
Se= 9.119 let’s call it 9.12
Now multiply standard error by value from t-dist table: 9.12*1.316 = 12.0019 let’s call it 12.
So now to find confidence interval of 80% subtract to find lower bound and add to find upper bound from given mean.
Upper: 305.3 + 12 = 317.3
Lower: 305.3 - 12 = 293.3

Four lines are shown on the grid above

(ii) write the equation of line L2

(iv)write the value (p) and (q) for the line y=px+q

B) which of the letters A to K lie in the region where
(i) x >=2. y>=mx +n. and y>=px+q
(ii) y<=2. y<=mx+n. And y<=px+q

C)what is the maximum value of x+y in the region G

Answers

The lines L1 & L2 and the equations y = mx + n & y = px + q are illustrations of linear equations

The equation of line L1

This is a vertical line that passes through the x = 2

So, the equation of line L1 is x = 2

The equation of line L2

This is a horizontal line that passes through the y = 2

So, the equation of line L2 is y = 2

The values of m and n in y = mx + n

The line y = mx + n passes through points (6,3) and (0,0)

This means that n = 0 i.e. the y-intercept.

The value of m is calculated as follows:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{0- 3}{0 - 6}[/tex]

[tex]m = 0.5[/tex]

So, the values of m and n in y = mx + n are 0.5 and 0, respectively.

The values of p and q in y = px + q

The line y = px + q passes through points (6,3) and (0,12)

This means that q = 12 i.e. the y-intercept.

The value of p is calculated as follows:

[tex]p = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]p = \frac{12- 3}{0 - 6}[/tex]

[tex]p = -1.5[/tex]

So, the values of p and q in y = px + q are -1.5 and 12, respectively.

The letters in the region x >=2. y>=mx +n and y>=px+q

The above region represent the upper region between y=mx +n, y=px+q and line L1

The letter in this region is letter H

The letters in the region y <=2. y<=mx +n and y<=px+q

The above region represent the lower region between y=mx +n, y=px+q and line L2

The letters in this region are letters A and E

Graph D is correct because linear functions are always straight lines. Linear functions have the base equation of y = mx + b . Because there is only one "x" value to the first power, the function increases by the same amount between each "x" value.

Bicyclist B's distance from the same town is shown in the graph .

Which THREE statements are TRUE?

A
B is traveling 1 mile per hour faster than A.

B
After 2 hours, A will have traveled a total of 28 miles.

С
B started from the town, while A started 5 miles from the town.

D
After 5 hours, the two bicyclists will be the same distance from the town.

E
When the two bicyclists reach the same point. A will have traveled 5 more miles than B.

Answers

The correct statement are statements B and C

Distance time graphs

Given the following equation for the distance of Bicyclist A expressed as:

d = 11.5h + 5

After 1 hour for A

d(1) = 11.5 + 5
d(1) = 16.5

For bicycle B, the distance traveled after 1 hour is 12.5 miles from the graph. Hence B is not traveling 1 mile per hour faster than A.

After 2 hours for A;

d(2) = 11.5(2) + 5

d(2) = 23 + 5 = 28 miles

Hence after 2 hours, A will have traveled a total of 28 miles.

From the graph, we can see that B started from the town (origin), and from the equation, A started from 5 miles from town (y-intercept is 5)

Hence the correct statement are statements B and C
