- 2x+4 what’s the answer

Answer:

About 198.6 feet

Step-by-step explanation:

This situation essentially forms a sideways triangle with height 80 feet. It can be divided into two right triangles, which you can each find the base length for, and then add them together to find the total height of the building.

Let's start with the lower base (with the angle measure of 56 degrees), which we'll call b. The tangent of an angle in a right triangle is the length of the opposite side divided by the length of the adjacent side, meaning that:

\(\tan 56=\dfrac{b}{80} \\\\b=80 \cdot \tan 56\approx 118.6\)

Now, let's do it for the upper part, which we'll call y:

\(\tan 45=\dfrac{y}{80} \\\\y=\tan 45 \cdot 80=1 \cdot 80 =80\)

Adding these together, you get a height of approximately 198.6 feet. Hope this helps!

Answer:

A:2

B:-5

C:8

D:-147

Step-by-step explanation:

A: For this one, you can cancel out the negatives. Then just divide 14 by 7. Your final answer is 2. Final Answer : 2

B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5

C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8

D: Multiply both numbers normally forgetting about the negative at first. 49 * 3 is 147. Now one of our numbers contain a negative so we plug back the negative into our answer. Final Answer : -147

The cosine of angle J is given as follows:

\(\cos{J} = \frac{14\sqrt{2}}{49}\)

The three trigonometric ratios are the sine, the cosine and the tangent of an angle, and they are obtained according to the rules presented as follows:

For the angle J in this problem, we have that:

Hence the cosine of angle J is given as follows:

\(\cos{J} = \frac{4}{\sqrt{98}} \times \frac{\sqrt{98}}{\sqrt{98}}\)

\(\cos{J} = \frac{4\sqrt{98}}{98}\)

\(\cos{J} = \frac{2\sqrt{98}}{49}\)

As 98 = 2 x 49, we have that \(\sqrt{98} = \sqrt{49 \times 2} = 7\sqrt{2}\), hence:

\(\cos{J} = \frac{14\sqrt{2}}{49}\)

What are scale drawings?

Scale drawings are drawings that are used to show the smaller dimensions of an actual object

The drawing is said to be a scale drawing of the actual hotel

This means that the drawing is a proportional drawing

And the scale factor of the drawing is given as 9 inches: 4 feet.

Rewrite the scale factor as

Scale factor = 9 inches : 4 feet

This means that

Scale measurement : Actual measurement = 9 inches : 4 feet

The room in the hotel is 36 inches

So, we have

36 inches : Actual measurement = 9 inches : 4 feet

Express the ratio as fraction

So, we have

36 inches/Actual measurement = 9 inches/4 feet

The above equation becomes

Actual measurement = 36 inches * 4 feet /9 inches

Evaluate

Actual measurement = 16 feet

Hence, the length of the actual room is 16 feet

Answer:

10 visits

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Rewards for signing up = 80 points

Reward per visit = 2.5 points

Total points needed = 105

Let, number of visits = x

So, we can calculate number of visits by using following formula,

80 + (2.5 × X) = 105

2.5X = 105 - 80

2.5X = 25

X = 25 ÷ 2.5

X = 10 visits.

Hence, Olivia needs to make 10 visits in order to earn a free movie ticket.

An integral calculator with steps is a tool that allows you to compute integrals of functions and provides a step-by-step solution to the problem.

This type of calculator is especially useful for students learning calculus, as it allows them to see how the integral is computed and helps them to understand the underlying concepts and techniques.

To use an integral calculator with steps, you typically enter the function you want to integrate and the limits of integration. The calculator then applies a variety of techniques to compute the integral, such as substitution, integration by parts, partial fractions, or trigonometric substitutions.

The output of the calculator usually includes the solution to the integral, as well as a detailed explanation of the steps involved in the computation. Some calculators may also provide graphs of the function and the area under the curve.

The given system of equations do not have a solution since their related line equations have the same slope.

The given system of equations is:

-x + 5y = 3   .......... (1)

2x - 10y = 4   ........(2)

In Equation (1), add both sides by (-5y)

-x + 5y + (-5y) = 3 + (-5y)

-x = -3 - 5y

Multiply by (-1)

x = 3 + 5y

Substitute x = 3 + 5y into equation (2)

2x - 10y = 4

2.(3 + 5y) - 10y = 4

6 + 10y - 10y = 4

6 = 4 (False)

Since the last equation is false, we might suspect that the given system of solution does not have solutions.

We need to check the slope of both equations:

-x + 5y = 3

⇒ 5y = x + 3

⇒ y = 1/5 x + 3/5

2x - 10y = 4

⇒ -10 y = -2x + 4

⇒ y = (2/10) x - 4/10

⇒ y = 1/5 x - 2/5

We can see that both equations have the same slope, i.e. 1/5.

Hence, they do not have solutions since the lines are parallel to each other.

A disk with a radius of 0.1 m is spinning about its center with a constant angular speed of 10 rad/sec. The speed of the bug is equal to the tangential speed of a point on the rim of the disk, which can be given by: v = rωWhere:r = 0.1 m (the radius of the disk)ω = 10 rad/sec (the angular speed of the disk)Therefore, the speed of the bug is: v = rω= 0.1 m x 10 rad/sec= 1 m/s

The acceleration of the bug can be given by: a = rαWhere:α = α (angular acceleration)The angular acceleration is zero because the disk is spinning at a constant angular speed. Hence, the acceleration of the bug is zero or a = 0 m/s². Therefore, the correct option is option 2) 1 m/s and 0 m/s² (Disk spins at a constant speed).

There are 360 possible pizza configurations possible.

To find the number of pizza configurations that a customer can choose, use the fundamental principle of counting where we multiply the number of choices for each category.

For the pizza size, there are 3 options to choose from.

For the toppings, there are 10 options for the first topping, 9 options for the second topping, and 8 options for the third topping.

However, since the order of the toppings doesn't matter (e.g. pepperoni, sausage, and mushroom is the same as mushroom, sausage, and pepperoni), we have to divide the result by the number of ways to arrange each group of toppings, which is 3! (factorial of 3).

So, the number of pizza configurations that a customer can choose can be calculated as follows:

Number of configurations = 3(10)(9)(8) / 3!

= 3(720) / 6

= 3(120)

= 360

Therefore, there are 360 possible pizza configurations that a customer can choose.

Answer:

\(y = 2x + 2\)

Step-by-step explanation:

The equation of any (non-vertical) line can take the form

y = ax + b where a is the slope and b is the y intercept. We know that in this case, the y intercept is 2. So we can substitute b = 2:

\(y = ax + 2.\)

Now, to find the x intercept, simply put y = 0 (since every point on the x axis has y = 0) and x = -1, since that is the given x intercept:

0 = -a + 2, so we see that a = 2. The equation is then:

y = 2x + 2

Given ,

5<x<10 and 8<y<19

For y-x,

8-5<y-x<19-10

3<y-x<9

The appropriate values to be used on the x and y axis are; w will represent the input values which will be on the x-axis while y will represent the output values which will be on the y-axis.

Usually, linear equation graphs are made up of the y-axis and x-axis values.

In this type of graph, the y-axis values are referred to as the range or output of the function while the x-axis values are referred to as the domain or input of the function.

Now, in the given question, we see that w is clearly the input function and as such will be represented on the x-axis while the output value will be represented on the y-axis.
