You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 7 ft. The base of the incline plane is 11 ft from the shelving unit. What is the length of the incline​ plane?

Answers

Answer 1

Answer:

We can use the Pythagorean theorem to solve this problem. Let's call the length of the incline plane "L". We know that the height of the shelving unit is 7 ft and the base of the incline plane is 11 ft. The hypotenuse of the right triangle formed by the incline plane, the floor, and the shelving unit will be the length of the incline plane. Using the Pythagorean theorem:

L^2 = 11^2 + 7^2

L^2 = 121 + 49

L^2 = 170

L = sqrt(170)

So the length of the incline plane is approximately 13.04 feet.

How many milliliter in 1 microliter?

Answers

From the given  information provided, by converting the units there are 0.001 milliliters in 1 microliter.

This means that if you have 1 microliter of liquid, it is equal to 0.001 milliliters of liquid.

The conversion factor between milliliters (mL) and microliters (μL) is:

1 mL = 1000 μL

Therefore, to convert microliters to milliliters, you divide the number of microliters by 1000.

For example, if you have 500 μL of liquid, you can convert it to milliliters by dividing 500 by 1000:

500 μL / 1000 = 0.5 mL

So, 500 microliters of liquid is equal to 0.5 milliliters of liquid.

Write an exponential function for a graph that passes through the points (3, 2.8) and (4, 5.6) . Write the function in the form y=a(b)x.

Answers

The formula of the given exponential function whose graph passes through the points (3, 2.8) and (4, 5.6) is :

   y = 0.35* (2)ˣ

What is an exponential function?

When the input variable x appears as an exponent in the formula

f(x) = aˣ, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x. It is mostly used to determine exponential growth or decay.

When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Over time, the rate of change quickens. As time goes on, the rate of increase accelerates. In exponential decay, the quantity initially falls very quickly and then gradually. Over time, the rate of change slows. As time goes on, change happens at a slower rate.

The general formula of an exponential function is:

y = abˣ

It is said that points (3, 2.8) and (4, 5.6) are present on the graph of the given exponential function.

W can substitute these value values in the above formula.

2.8 = ab³

5.6 = ab⁴

Dividing the above equations,

2.8 /5.6 = b³/b⁴

1/2 = 1/b

b = 2

Now substituting this value in one of the equations to find the value of a.

2.8 = a. (2)³

a = 2.8/8 = 0.35

Therefore the formula of the given exponential function is :

   y = 0.35* (2)ˣ

The result of a number, when decreased by 66 2/3%, is 432. Find the number

Answers

Answer:

1298/3 is the answer

Step-by-step explanation:

Answer:

1296

Step-by-step explanation:

Let the unknown number be x.

If 432 is the result of x being decreased by 66²/₃%, then 432 is 33¹/₃% of x since 100% - 66²/₃% = 33¹/₃%.

Therefore:

[tex]\implies 33\frac{1}{3}\%\;\textsf{of}\;x=432[/tex]

[tex]\implies \dfrac{33\frac{1}{3}}{100} \cdot x=432[/tex]

[tex]\implies \dfrac{33\frac{1}{3}x}{100} =432[/tex]

Multiply both sides of the equation by 100:

[tex]\implies 33\frac{1}{3}x =43200[/tex]

Rewrite 33¹/₃ as an improper fraction:

[tex]\implies \dfrac{100}{3}x =43200[/tex]

Multiply both sides by 3:

[tex]\implies 100x=129600[/tex]

Divide both sides by 100:

[tex]\implies x=1296[/tex]

Therefore, the number that when decreased by 66²/₃% is 432, is 1296.

At what points does the helix r(t) = sin(t), cos(t), t intersect the sphere x2 + y2 + z2 = 26? (round your answers to three decimal places. If an answer does not exist, enter dne. ).

Answers

At (0.958, 0.287, 5) and (0.958, -0.287, -5) points, the helix r(t) = sin(t), cos(t), t intersect the sphere x^2 + y^2 + z^2 = 26.

The sphere x^2 + y^2 + z^2 = 26 is a sphere with center at the origin and radius sqrt(26).

The helix r(t) = sin(t), cos(t), t is parameterized by sine and cosine functions, which oscillate between -1 and 1.

To find the points at which the helix intersects the sphere, we need to find the values of t such that the distance between r(t) and the origin is equal to sqrt(26).

The distance between a point (x, y, z) and the origin is given by the formula:

d = sqrt(x^2 + y^2 + z^2)

So, substituting the values from r(t), we have:

d = sqrt(sin^2(t) + cos^2(t) + t^2)

Setting d equal to sqrt(26), we have:

sqrt(sin^2(t) + cos^2(t) + t^2) = sqrt(26)

Squaring both sides, we have:

sin^2(t) + cos^2(t) + t^2 = 26

Recall that sin^2(t) + cos^2(t) = 1, so we have:

1 + t^2 = 26

Subtracting 1 from both sides, we have:

t^2 = 25

Taking the square root of both sides, we have:

t = ±5

So, the two points of intersection are (sin(5), cos(5), 5) and (sin(-5), cos(-5), -5).

Rounding the results to three decimal places, we have:

(sin(5), cos(5), 5) = (0.958, 0.287, 5)

(sin(-5), cos(-5), -5) = (0.958, -0.287, -5)

The scale factor for the dilation that maps △ABC to △DEF is 0.75.

What is triangle?

A triangle is a geometric shape that consists of three line segments that connect to form three angles. These angles always add up to 180 degrees. A triangle has three sides and three vertices (corners). Triangles can have different shapes and sizes, and they are often classified based on the length of their sides or the size of their angles. Some common types of triangles include equilateral triangles (where all sides are equal in length and all angles are equal to 60 degrees), isosceles triangles (where two sides are equal in length), and right triangles (where one angle is a right angle, or 90 degrees). Triangles have many properties and are an important part of geometry and mathematics.

Here,

To determine the scale factor for the dilation that maps △ABC to △DEF, we need to find the ratio of the corresponding side lengths of the two triangles.

Since △ABC ∼ △DEF, we know that the corresponding angles of the two triangles are congruent. Therefore, angle B in △ABC corresponds to angle E in △DEF, and angle A in △ABC corresponds to angle D in △DEF.

Using the Pythagorean theorem, we can find the length of the missing side of △DEF:

The domain and range of the function for the given graph is -

Domain : (-∞, + ∞)Range: [3, ∞)Define the term domain and range of the function?

The range of values which we're permitted to enter into our function is known also as domain of a function.

The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.The collection of all potential inputs for a function is its domain.The collection of potential output values for a function is known as its range. For instance, the range seems to be the non-negative real numbers for the function f(x)=x2 here on domain among all real numbers (xR), which may be represented as f(x)≥0 (or [0,∞) using interval notation).

Thus, the domain and range of the function for the given graph is -

Solve for lengths of the missing sides in each pair of similar triangles. Round to nearest tenth if if necessary jk kl

Answers

For the given similar triangles, the length of the missing side in the second triangle is 20.

To solve for the length of the missing side in the pair of similar triangles, we can use the SSS similarity theorem. The theorem states that 'if all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar'. Since the triangles are similar, the ratio of their corresponding sides will be equal.

The given measurements of the first triangle are 12, 18, and 24, and the measurements of the second triangle are 10, 15, and x. To solve for x, you can use the ratio of corresponding sides of similar triangles. The ratio for the sides of the first triangle are 12:18:24 and for the second triangle are 10:15:x. The ratio of the corresponding sides is 10:12, 15:18, and x:24.

We can set up a proportion using the given dimensions and solve for x.

The proportion will look like this:

12/10 = 18/15 = 24/x

Cross-multiplying and simplifying, we get:

12x = 240

x = 20

Therefore, the length of the missing side in the second triangle is 20.

Note: The question is incomplete. The complete question probably is: Solve for length of the missing side in the pair of similar triangles. The dimensions of one triangle are 12, 18, and 24, and the dimensions of the second triangle is 10, 15, and x. (These are corresponding measurements).
