Answer:

[tex]x=66[/tex]

Step-by-step explanation:

Since  MN and MP are tangent to circle O, they create 90° angles at the points of intersection.

We also know that this is a quadralateral, so the interior angles add up to 360.

We can make an equation with this information.

[tex]114+90+90+x=360[/tex]

[tex]294+x=360[/tex]

[tex]x=66[/tex]

By property of tangent, the value of x is Option(C) 66° .

The properties of tangent are as follows -

Given that point O is the center if the circle also given MN and MP are tangent to O.

Thus by the property of tangent, ∠OPM and ∠ONM is equal to 90° as both the tangents intersect at the points P and N .

Also from property, we know that -

⇒ ∠ONM + ∠OPM + 114° + x° = 360°

⇒  90° + 90° + 114° + x° = 360°

⇒ 294° + x° = 360°

∴  x = 360° - 294° = 66°

Therefore, by property of tangent, the value of x is Option(C) 66° .

Answer:

x=36

Step-by-step explanation:

The angle right under 3x is 2x, because alternate exterior angles between parallel lines are equal. Those two angles add up to 180, because they are formed by a strait line intersecting with another straight line. This means that 5x = 180 or x=36.

Answer:

y =1/27

Step-by-step explanation:

Howdy!

If P = (-3, y) lies on the graph of y=3^x, then, to find the value of 'y' we need to substitute the point P into the equation:

To solve this, remember that [tex]a^{-b} = \frac{1}{a^{b}}[/tex]

Then:

y = 3^x

y = 3^(-3)

y = 1/27

So P= (-3, 1/27)

The correct option is y =1/27

Answer:

The correct answer option is 1/27.

Step-by-step explanation:

We are given the following equation and we are to find the value of y when the point (-3, y) lies on the graph of the given equation:

[tex] y = 3 ^ { x } [/tex]

So we will substitute the given value of x from the point (-3, y) in the equation to get y:

[tex] y = 3 ^ { - 3 } [/tex]

[tex] y = \frac { 1 } { 2 7 } [/tex]

Answer:

The range of f(x) is {-2 , 16 , 34 , 52} ⇒ answer d

Step-by-step explanation:

* Lets talk about the domain and the range of a function

- The domain is the values of x (input)

- The range is the value of y of the corresponding x (output)

∵ f(x) = 3x + 4

∵ The domain is {-2 , 4 , 10 , 16}

- To find the corresponding range substitute the values of x in f(x)

∵ x = -2

- Substitute x by -2 in f(x)

∴ f(-2) = 3(-2) + 4 = -6 + 4 = -2

∵ x = 4

- Substitute x by 4 in f(x)

∴ f(4) = 3(4) + 4 = 12 + 4 = 16

∵ x = 10

- Substitute x by 10 in f(x)

∴ f(10) = 3(10) + 4 = 30 + 4 = 34

∵ x = 16

- Substitute x by 16 in f(x)

∴ f(16) = 3(16) + 4 = 52

∴ The range of f(x) is {-2 , 16 , 34 , 52}

The surface area of the pyramid is 156 square inches. It is found by computing the area of the base, then adding it with the product of half of the base perimeter and the slant height.

The problem involves finding the surface area of a pyramid with a square base. The surface area of a pyramid is given by the formula Base area + 1/2 * Perimeter of the base * Slant height.

First, let's compute the area of the base, the base is a square with sides of 6 inches. This gives us 6 * 6 = 36 square inches.

Secondly, the perimeter of a square is simply the length of one side multiplied by 4, which gives us 6*4 = 24 inches. Then multiply this by the slant height, which is 10 inches, then by 1/2, we have 0.5 * 24 * 10 = 120 square inches.

Finally, adding the base area and the latter computation gives: 36 + 120 = 156 square inches. Therefore, the surface area of the wooden pyramid puzzle is 156 square inches.

The surface area of the wooden pyramid puzzle with a base side length of 6 inches and a slant height of 10 inches is 156 square inches.

To find the surface area of the wooden pyramid puzzle, we need to calculate the area of each face and then sum them up. The base of the pyramid is a square with side lengths of 6 inches, so the area of the base is 6 inches multiplied by 6 inches, which gives us 36 square inches. The four triangular faces have the same area since the pyramid is symmetrical, so we just need to calculate the area of one triangular face.

The height of the pyramid is given as 10 inches, and since it is a right triangle, we can use the formula for the area of a triangle: (base x height) / 2.

The base of the triangle is the length of one side of the square base, which is 6 inches. Therefore, the area of one triangular face is (6 inches x 10 inches) / 2 = 30 square inches.

Since there are four triangular faces, the total area for all the triangular faces is 4 x 30 square inches = 120 square inches. Finally, we can sum up the areas of the base and the triangular faces to find the surface area: 36 square inches + 120 square inches = 156 square inches.

there are 80 buttons

7/10

3÷24=8 8×7=56 56+24=80

The total number of buttons in the container is 60. This was calculated by setting up an equation using the given proportion of black buttons and the difference between the number of black and white buttons.

Let the total number of buttons in the container be x. Given that 7/10 of the buttons are black, this means 7/10 of x, or (7/10)x, represent the number of black buttons. The remaining 3/10 of x are white buttons. The difference between the number of black and white buttons is 24, so we can set up the following equation:

(7/10)x - (3/10)x = 24.

Simplifying the equation by subtracting the fractions results in (4/10)x = 24.

We can then simplify this further by dividing both sides by the coefficient of x, which is (4/10), to find x.

x = 24 / (4/10) = 24 * (10/4) = 24 * (2.5) = 60.

So, there are 60 buttons in the container in total.

Answer:

the answer is B.  145 sq. ft.

Step-by-step explanation:

find the area of the first 2 triangles

A = 1/2 bh

A = 1/2 ba

a = 1/2 (11 ft.) (5 ft)

a =  27.5 sq ft.

A = 1/2 cb

a = 1/2 (5 ft) (7 ft)

a = 17.5 sq. ft

find the area of the rectangle

A = lw

a = (11 ft.)(5 ft.)

a = 55 sq. ft

Then add all together

2(27.5 sq.ft) + 2(17.5 sq. ft) + 55 sq.ft. = 145 sq. ft.

Answer:

P = 83%

Step-by-step explanation:

In this problem we have the ages of all new employees hired during the last 10 years of normally distributed.

We know that the mean is [tex]\mu = 31[/tex] years and standard deviation is [tex]\sigma = 10[/tex] years

By definition we know that if we take a sample of size n of a population with normal distribution, then the sample will also have a normal distribution with a mean

[tex]\mu_m = \mu[/tex]

And with standard deviation

[tex]\sigma_m = \frac{\sigma}{\sqrt{n}}[/tex]

Then the average of the sample will be

[tex]\mu_m = 31\ years[/tex]

And the standard deviation of the sample will be

[tex]\sigma_m =\frac{10}{\sqrt{10}} = 3.1622[/tex]

Now we look for the probability that the mean of the sample is greater than or equal to 28.

This is

[tex]P ({\displaystyle{\overline {x}}}\geq 28)[/tex]

To find this probability we find the Z-score

[tex]Z = \frac{X -\mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = \frac{28 -31}{\frac{10}{\sqrt{10}}} = -0.95[/tex]

So

[tex]P({\displaystyle{\overline {x}}}\geq 28) = P(\frac{{\displaystyle {\overline {x}}}-\mu}{\frac{\sigma}{\sqrt{n}}}\geq\frac{28-31}{\frac{10}{\sqrt{10}}}) = P(Z\geq-0.95)[/tex]

We know that

[tex]P(Z\geq-0.95)=1-P(Z<-0.95)[/tex]

Looking in the normal table we have:

[tex]P(Z\geq-0.95)=1-0.1710\\\\P(Z\geq-0.95) = 0.829[/tex]

Finally P = 83%

Answer:

(-6,4)

Step-by-step explanation:

The equations are:

[tex]x^2+4y^2=100\\4y-x^2=-20[/tex]

Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:

[tex]4y-x^2=-20\\x^2=4y+20\\-------\\x^2+4y^2=100\\4y+20+4y^2=100[/tex]

Now we can solve for y:

[tex]4y+20+4y^2=100\\4y^2+4y-80=0\\y^2+y-20=0\\(y+5)(y-4)=0\\y=4,-5[/tex]

So plugging in y = 4 into an equation and solving for x, we have:

[tex]x^2=4y+20\\x=+-\sqrt{4y+20} \\x=+-\sqrt{4(4)+20} \\x=+-\sqrt{36} \\x=6,-6[/tex]

So y = 4 corresponds to x = 6 & x = -6

The pairs would be

(6,4) & (-6,4)

we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.

Final answer:

The correct answer is D. Distance formula to prove AC and BD are congruent, as this explains why the diagonals of a rectangle, AC and BD, are always the same length.

Explanation:

The question asks which reason validates the statement: "The diagonals of a rectangle are congruent." The correct answer is D. Distance formula to prove AC and BD are congruent. In a rectangle, the diagonals are always congruent because they connect opposite corners and because a rectangle is a parallelogram, where opposing sides are equal and parallel, making the trip from one corner to the opposite across the shape the same distance, regardless of the starting and ending points. This is proven using the distance formula, which calculates the distance between two points in a coordinate plane. The diagonal AC and diagonal BD represent these distances in a rectangle.

Recall that,

[tex] {a}^{ - m} = \frac{1}{ {a}^{m} } [/tex]

[tex]{( - 2)}^{ - 3} = \frac{1}{{( - 2)}^{ 3}} [/tex]

We multiply out to get,

[tex]{( - 2)}^{ - 3} = \frac{1}{{- 2} \times - 2 \times - 2} [/tex]

[tex]{( - 2)}^{ - 3} = \frac{1}{ - 8} [/tex]

The correct choice is B.

The answer is 14

0.4r-7=-.3r+2.8

Add 7 to both sides. -7+7=0 so it cancels on the left. 2.8+7=9.8.

0.4r=-.3r+9.8.

Add .3r to both sides. -.3r+3r=0 so it cancels on the right. 0.4r+.3r=0.7r.

0.7r=9.8

Divide 0.7 to both sides. 9.8 divided by 0.7 = 14

So r=14
