The minimum length Starbucks must build the wheel chair ramp to meet the standards is 23.9ft.

A triangle in which one of the angles is 90 degrees is called a Right angled Triangle.

To find the angle of the ramp, Trigonometric Ratios will be used

As the ramp is forming a right triangle

sin x = 2/22

x = 5.21°

The angle the wheel chair ramp makes with the ground is 5.21°.

If the angle has to be less than 4.8°

Let the length of the wheel chair will be given by y

Then,

2/x < sin4.8

x > 2/sin 4.8

x > 23.9 ft

Therefore the minimum length Starbucks must build the wheel chair ramp to meet the standards is 23.9ft.

The altitude of an object with respect to a reference plane or point is termed its height. This includes all parts of the object that add up to its height. Therefore, the height of the wall would be 100.5 inches.

The height of a given object implies the altitude of the object from a reference plane or point.

Therefore given that concrete blocks are 8 inches, then;

total height of mortar required to hold each concrete block = 3/8 inches

Thus, since there are 12 concrete blocks, then 12 sections of mortar would be required to hold 12 blocks starting from the ground.

So that;

total height of mortar required = 3/8 x 12

                                         = 4.5 inches

Total height of all concrete blocks required = 12 x 8

                                                             = 96 inches

Therefore, the height of the wall of 12 courses of concrete blocks = 96 + 4.5

                                                   = 100.5 inches

I believe so because the 20 pole took away six so im guessing the 41 pole will to the same

The length of the shadow cast by the 14-foot pole is 8.4 shadows.

We have,

From the figure given,

The two triangles are similar since the corresponding sides and angles are given equal.

This means,

The ratio of the corresponding sides is equal.

So,

20/14 = 12/x _______(1)

Where x is the length of the shadow cast by the 14-foot pole.

Now,

Solving for x from (1).

20/14 = 12/x

Divide 12 on both sides.

20 / (14 x 12) = 1/x

20/168 = 1/x

Cross multiply.

x = 168/20

x = 8.4 shadow.

Thus,

The length of the shadow cast by the 14-foot pole is 8.4 shadows.

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The width of a rectangle is 13 units less than the length.

If the area is 90 square units.

W = L – 13

6 seconds after it is launched

Step-by-step explanation:

h(t) = -4t² + 16t + 48

The balloon is at ground level when it lands.

When it is launched, t = 0, and h(0) = 48

When it lands, at time t, h(t) = 0.

-4t² + 16t + 48 = 0

t² - 4t - 12 = 0

(t - 6)(t + 2) = 0

t = 6 or t = -2

The measure of arc BEC in circle D is 134°

From the question, we are to determine the measure of arc BEC

Measure of arc BEC = 2 × m∠BAC

First, we will determine the measure of angle ACB

From one of the circle theorems,

The angle subtended by an arc of a circle is twice the angle it subtends anywhere on the circle's circumference

∴ m∠ACB = 1/2 × 76°

m∠ACB = 38°

Then,

m∠BAC + m∠ACB + m∠ABC = 180° (Sum of angles in a triangle)

m∠BAC + 38° + 75° = 180°

m∠BAC + 113° = 180°

m∠BAC  = 180°- 113°

m∠BAC = 67°

Then,

Measure of arc BEC = 2 × m∠BAC

Measure of arc BEC = 2 × 67°

Measure of arc BEC = 134°

Hence, the measure of arc BEC is 134°

Step-by-step explanation:

Using simpler trigonometric identities, the given identity was proven below.

Remember that:

[tex]sec(x) = \frac{1}{cos(x)} \\\\tan(x) = \frac{sin(x)}{cos(x)}[/tex]

Then the identity can be rewritten as:

[tex]sec^4(x) - sen^2(x) = tan^4(x) + tan^2(x)\\\\\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)} = \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)} \\\\[/tex]

Now we can multiply both sides by cos⁴(x) to get:

[tex]\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)} = \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)} \\\\\\\\cos^4(x)*(\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)}) = cos^4(x)*( \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)})\\\\1 - cos^2(x) = sin^4(x) + cos^2(x)*sin^2(x)\\\\1 - cos^2(x) = sin^2(x)*sin^2(x) + cos^2(x)*sin^2(x)[/tex]

Now we can use the identity:

sin²(x) + cos²(x) = 1

[tex]1 - cos^2(x) = sin^2(x)*(sin^2(x) + cos^2(x)) = sin^2(x)\\\\1 = sin^2(x) + cos^2(x) = 1[/tex]

Thus, the identity was proven.

We have to evaluate the above sum.

Now -

f(x) + g(x) = 3x + 9 - (6 - x)  

f(x) + g(x) = 3x + 10 - 6 + x

f(x) + g(x) =  4x + 4

f(x) + g(x) = 4(x + 1)

According to the question, we have -

(y + 5) + (3y - 9)

Assume that the sum is represented by the function f(y).

Solving, we get -

f(y) = y + 5 + 3y - 9

f(y) = y + 3y + 5 - 9

f(y) = 4y - 4

f(y) = 4(y - 1)

Answer:

[tex]\frac{2\sqrt3}{3} = x[/tex]

Step-by-step explanation:

So you want to use PEMDAS to do the equation in order. This means that you'll start by adding 6 and 1 and then multiplying that value by 2

[tex]2(7)-|-10| = 3x^2[/tex]

[tex]14-|-10|=3x^2[/tex]

The absolute value can be defined as the "distance" from 0 which is going to be positive. You can think of it as the positive value of a number so if you have |-b| it will become b, and even if it's already positive, it will remain positive. so the absolute value of -10 is 10 but then it becomes negative again because of the subtraction

[tex]14-10=3x^2[/tex]

[tex]4=3x^2[/tex]

Now you want to solve for x by dividing both sides by 3 and taking the square root of both sides to isolate x

[tex]\frac{4}{3} = x^2[/tex]

[tex]\sqrt{\frac{4}{3}}=x[/tex]

You can distribute the square root across division since [tex](\frac{a}{b})^c = \frac{a^c}{b^c}[/tex] and the square root can be defined as [tex]x^{0.5}[/tex] since [tex]a^b * a^c = a^{b+c}[/tex] because if you spread it out it's really just [tex](a * a * a ... b\ amount \ of \ times) * (a * a * a ... c\ amount\ of\ times)[/tex] which can be simplified to (a * a * a... (b + c) amount of times) if that makes any sense. Anyways using this property you'll get [tex]a^{0.50} * a^{0.50} = a^{0.50 + 0.50} = a^1 = a[/tex]. If you look at it you'll notice a^0.50 multiplied by it self gives you a... sounds like the square root, which it is. So now the equation becomes

[tex]\frac{\sqrt{4}}{\sqrt{3}}=x[/tex]

[tex]\frac{2}{\sqrt3}[/tex]

Now if you look at the equation you'll notice there's a radical in the denominator, which can be rationalized by multiplying by sqrt(3)\sqrt(3) which is 1 except it makes the denominator 3 and keeps the original value

[tex]\frac{2}{\sqrt3} * \frac{\sqrt3}{\sqrt3}=x\\\frac{2\sqrt{3}}{3} = x[/tex]
