A person whose eye level is 11 ft above the ground is looking at a building. The angle of elevation to the top of the building is 22 degrees and the angle of depression to the bottom of the building is 34 degrees. What is the height (in feet) of the building? Round your answer to the nearest foot.

Answer:

It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

Answer:

B. f(x) = 3x + 5

Step-by-step explanation:

Initial amount of bacteria N0 = 5 bacteria's

If the triple every hour,

The increase in bacteria in the colony after x hour will be 3*x =3x

x is the amount of hour.

Total amount of bacteria in the colony after x hour will be N0 + 3x

Let f(x) be the total amount of bacteria in the colony after x hour

f(x) = N0+3x

Since N0 = 5

f(x) = 5+3x

Re-arrange

f(x) = 3x + 5

Hence an explicit formula to model the equation is f(x) = 3x + 5

Answer:1606

Step-by-step explanation:

Step-by-step explanation:

length=x

width=x-1

x + x + (x-1) + (x-1) = 54

4x - 2 = 54

4x = 56

x = 14 ft

x = 14 ft

x - 1 = 14 - 1 = 13 ft

x = 14 ft

x - 1 = 14 - 1 = 13 ft

Perimeter= x + x + (x-1) + (x-1)

54 ft = 14 + 14 + (14 - 1) + (14 - 1)

54 ft = 28 + (13 +13)

54 ft = 54 ft

Explanation:

5 & 1/3 is the mixed number with 5 as the whole part and 1/3 as the fractional part

Let's convert to an improper fraction

5 & 1/3 = 5 + 1/3

5 & 1/3 = 5*(3/3) + 1/3

5 & 1/3 = 15/3 + 1/3

5 & 1/3 = (15+1)/3

5 & 1/3 = 16/13

The mixed number 5 & 1/3 is equivalent to the improper fraction 16/3

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

Each serving is 7/8 cup

x of these servings is (7/8)x

x is the number of servings in a full container, so

(7/8)x = 16/3

x = (16/3)*(8/7)

x = (16*8)/(3*7)

x = 128/21

x = 6.0952 approximately

x = 6 when rounding to the nearest whole number

So the container is about 6 servings.

Two x-intercepts match up to more than one y-intercept.

[tex]\angle 1 = 78\\\angle 2 = 102\\\angle 3 = 78\\\angle 4 = 102\\\angle 5 = 38\\\angle 6 = 142\\\angle 7 = 38\\\angle 8 = 142\\\angle 9 = 78\\\angle 10 = 102\\\angle 11 = 78\\\angle 12 = 102\\\angle 13 = 38\\\angle 14 = 142\\\angle 15 = 38\\\angle 16 = 142[/tex]

The measure of the angles will be ∠1 = 78°, ∠2 = 102°, ∠3 = 78°, ∠4 = 102°, ∠5 = 38°, ∠6 = 142°, ∠7 = 38°, ∠8 = 142°, ∠9 = 78°, ∠10 = 102°, ∠11 = 78°, ∠12 = 102°, ∠13 = 38°, ∠14 = 142°, ∠15 = 38°, and ∠16 = 142°

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

The type of angles is given below.

The measure of angle 7 is 38°. Angles 7 and 8 are supplementary angles.

∠7 + ∠8 = 180°

38° + ∠8 = 180°

∠8 = 142°

The measure of angle 10 is 102°. Angles 9 and 10 are supplementary angles.

∠9 + ∠10 = 180°

102° + ∠9 = 180°

∠9 = 78°

Then the measure of the remaining angles will be

∠1 = 78°

∠2 = 102°

∠3 = 78°

∠4 = 102°

∠5 = 38°

∠6 = 142°

∠7 = 38°

∠8 = 142°

∠9 = 78°

∠10 = 102°

∠11 = 78°

∠12 = 102°

∠13 = 38°

∠14 = 142°

∠15 = 38°

∠16 = 142°

140

165

Step-by-step explanation:

To solve the absolute value equation, first rewrite the equation as two separate equations equal to -100 and 100:

8t − 1,220 = -100 8t − 1,220 = 100

8t = 1,120 8t = 1,320

t = 140 t = 165

To earn within $100 of its goal, the theater club needs to sell a minimum of 140 tickets and a maximum of 165 tickets.

Given expressions;

     f(x) = x² + 6x + 7

     g(x) = 8x² - 2

     h(x) = 3x + 4

     k(x) = x - 3

Find  f(2) - g(2). k(2)

f(2) = 2² + 6(2) + 7 = 23

g(2) = 8(2)² - 2 = 30

k(2) = 2 - 3 = -1

Now,  f(2) - g(2). k(2) = 23  - (30)(-1)

                                  = 53

The solution to the problem is 53

Answer:

y = 1 cm

x = 7 cm

Step-by-step explanation:

x = 3y + 4

perimeter = 2 * ( y + x ) = 16

x + y = 8 by using x = 3y + 4

y + 3y + 4 = 8

4y = 4

y = 1

1 + x = 8

x = 7

D) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis​

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.

If a point X(x, y) is translated a units right and b units down, it new location is X'(x + a, y + b)

If a point X(x, y) is reflected across x axis, it new location is X'(x, -y)

Pentagon ABCDE is at A(-4, 5), B(-6, 4), C(-5, 1), D(-2, 2), E(-2, 4) while pentagon A"B"C"D"E" is at A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)

If pentagon ABCDE is Translated according to the rule (x, y) → (x + 8, y + 2), the new points would be A'(4, 7), B'(2, 6), C'(3, 3), D'(6, 4), E'(6, 6). If a reflection across the x axis is the done, the new points are A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)

Answer:

y=0,4 and x=8,0

The x and y-intercept of the linear equation 3x + 6y = 24 will be (8,0) and (0,4) respectively.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given linear function,

3x+6y=24

At x-intercept, y = 0

3x = 24

x = 8 thus it will be (8,0).

At y-intercept , x = 0

6y = 24

y = 4 thus it will be (0,4)

Hence "The linear equation 3x + 6y = 24 will have x-intercepts of (8, 0) and (0, 4) correspondingly".

Answer:

Brandon is correct.

Step-by-step explanation:

Initially, there id 4 pints of green paint in the bucket.

As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket  is 2 pint each.

Let x pints of yellow paint to be added to the bucket to make the desired shade.

Total amount of the paint in the bucket, after addition of [tex]x[/tex] pints of yellow color become [tex]4 + x[/tex] pint, in which the ampunt of yellow color is [tex]2+x[/tex] pints.

As, the ampunt of yellow color is 80% of the total amount of the mixture, so

[tex](4+x)\times 80\%=2+x[/tex]

[tex]\Rightarrow (4+x)\times \frac{80}{100}=2+x[/tex]

[tex]\Rightarrow 4(4+x)=5(2+x)[/tex]

[tex]\Rightarrow x=6[/tex]

So, 6 pints of yellow paint to be added to the bucket to make the desired shade.

Hence, Brandon is correct.

Answer:

Brandon is correct that the mixture needs 6 more pints of yellow paint.

50%(4 pints) + 100%(x pints) = 80%(4 + x pints)

2 + x = 3.2 + 0.8x

0.2x = 1.2

x = 6

Bianca is correct because adding the 6 pints won't fit in the gallon bucket. Adding 6 pints of yellow to the original 4 pints of green is 10 pints, which will not fit in the 1-gallon bucket. (1 gallon = 8 pints)
