Answer:

Step-by-step explanation:

3/4 * 1/8 = 3*1 / 4*8

3 / 32 is the solution.

Answer:

Step-by-step explanation:

The sum is given by -  f(y) = 4(y -1).

We have the following expression -

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

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)

Hence, the sum is given by -  f(y) = 4(y -1).

Step-by-step explanation:

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.

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]

Answer:

Milk and Eggs = 552

Step-by-step explanation:

First add all of the other percentages together. (70%), 100%-70%=30%. 30% of 1840 = 552.

Answer:

H.  552

Step-by-step explanation:

Circle graph information:

Total consumption = 1840 pounds per person

First, calculate the percentage of milk and eggs (the value of x).

Total percentages = 100%

⇒ x + 38 + 10 + 10 + 8 + 4 = 100

⇒ x + 70 = 100

⇒ x = 30

Therefore, 30% of food consumption is milk and eggs.

To calculate the number of pounds of milk and eggs the average American consumes each year, simply find 30% of the total consumption:

= 30% of 1840

= 30% × 1840

[tex]=\sf \dfrac{30}{100} \times 1840[/tex]

= 552

Therefore, the average American consumes 552 pounds of milk and eggs each year.

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°

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

Answer:

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 balloon will hit the ground 6 seconds after it is launched.

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

Answer:

y=3/2x + 18

Step-by-step explanation:

So when two lines are perpendicular, that simple means the slope are reciprocals, and the signs are opposite. So for example if one equation had a slope of [tex]\frac{a}{b}[/tex], the equation that is perpendicular, would have a slope of [tex]-\frac{b}{a}[/tex]. So the first step would be to find the slope of 2x+3y=4. To find the slope we can convert it into slope-intercept form which is y=mx+b where m is the slope, and this is done by isolating y, as you can see the y is alone in the slope-intercept form.

Original equation:

2x + 3y = 4

subtract 2x from both equations:

3y = -2x + 4

Divide both sides by 3

y = -2/3x + 4/3

The y-intercept doesn't really matter in this case, what really matters is the slope, and the slope is the coefficient of x, since as x increases by 1, it will increase by the amount of the coefficient, because the slope is rise/run and since the run is 1, if you increase x by 1, the run is the slope, which is the coefficient. The slope in this case is -2/3. So the reciprocal of the slope is 3/2 (notice how the sign is the opposite as well). Now we have the equation

y=3/2x + b

To find the y-intercept, you simply use the point that was given (-2, 15). Plug in -2 as x, and 15 as y to find the value of b

Original equation

y=3/2x + b

Plug in known values:

15 = 3/2(-2) + b

Multiply the fraction:

15 = -6/2 + b

Simplify the fraction:

15 = -3 + b

Add 3 to both sides

18 = b

This gives you the equation

y=3/2x + 18

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]
