Answer:

0 to StartFraction pi Over 2

Step-by-step explanation:

we know that

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

so

The central angle in degrees is within the range [tex](0,90^o)[/tex]

Convert to radians

Remember that

[tex]\frac{\pi}{2}\ radians=90^o[/tex]

therefore

the range in radians is [tex](0,\frac{\pi}{2})[/tex]

0 to StartFraction pi Over 2

Answer: A. 0 to pi/2 radians

Step-by-step explanation:

Answer: [tex]y=0[/tex]

Step-by-step explanation:

For this exercise it is important to remember:

1. The Product of powers property. This property states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

2. The multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then, given:

[tex]8^3*8^{-5}*8^y=8^{-2}=\frac{1}{8^2}[/tex]

You can identify that [tex]8^{-2}[/tex] is obtained by applying the Product of powers property:

[tex]8^{3+(-5)+y}=8^{-2}=\frac{1}{8^2}[/tex]

Based on the explained above, you can write the following equation:

[tex]3+(-5)+y=-2[/tex]

Therefore you must solve for the variable "y" in order to find its value. You get that this is:

[tex]3-5+y=-2\\\\-2+y=-2\\\\y=-2+2\\\\y=0[/tex]

Answer:

You're trying to find the value of y that would result in 8^-2. When you multiply terms with the same base, you can add the exponents. 3+-5=-2 and -2-(-2) equals 0, so therefore y is equal to 0.

6x-27-4x=4x-17-4x

2x-27=-17

The equations used to find the length of leg of triangle are:

[tex]0.5x(x+2) = 24\\\\x^2+2x-48=0\\\\x^2+(x+2)^2 = 100[/tex]

Solution:

From given,

Area of right triangle = 24 square feet

Also from given figure in question (attached below )

base = x and height = x + 2

The area of triangle is given by formula:

[tex]Area = \frac{1}{2} \times base \times height[/tex]

Substituting the values we get,

[tex]24 = \frac{1}{2} \times x \times (x+2)\\\\24 = 0.5x(x + 2)\\\\48 = x(x+2)\\\\x^2 + 2x - 48 = 0\\\\[/tex]

Also, the above equation can be written as,

[tex]x^2 + (x+2)^2 =100[/tex]

Thus the equations used to find the length of leg of triangle are:

[tex]0.5x(x+2) = 24\\\\x^2+2x-48=0\\\\x^2+(x+2)^2 = 100[/tex]

Answer:

A, D, E

Step-by-step explanation:

From the answer above, but the letters to make it easier :)

Step-by-step explanation:

We have,

[tex]-16(0.47)^2[/tex]

To find, the value of [tex]-16(0.47)^2[/tex] = ?

∴ [tex]-16(0.47)^2[/tex]

= [tex]-16(\dfrac{47}{100} )^2[/tex]

= [tex]-16\times \dfrac{47}{100}\times \dfrac{47}{100}[/tex]

= [tex]-4\times \dfrac{47}{25}\times \dfrac{47}{100}[/tex]

= [tex]- \dfrac{47}{25}\times \dfrac{47}{25}[/tex]

=[tex]- \dfrac{2209}{625}[/tex]

= - 3.5344

∴ The value of [tex]-16(0.47)^2[/tex] = - 3.5344

Thus, the value of [tex]-16(0.47)^2[/tex] is equal to - 3.5344.

What will be the population after 5 years is 20,683.

Using this formula

A=P(1+r/100)^n

Where:

P=17000

r=4%

n=5 years

Let plug in the formula

P=17,000(1+0.04)^5

P=17,000×(1.04)^5

P=17,000×1.2166529

Answer:

x= 14√3

y= 28√3

Step-by-step explanation:

Please see attached picture for full solution.

(tan30° and cos30° are special angles so there's an exact value to it in which we can memorise.)

In this case, by Pythagoras's Theorem, you should ensure that:

[tex] {y}^{2} = 42^{2} + {x}^{2} [/tex]

✓ Let's check:

[tex]{y}^{2} = (28 \sqrt{3} )^{2} \\ y^{2} = 2352 \\ {x}^{2} + {42}^{2} = ( 14\sqrt{3})^{2} + 1764 = 2352[/tex]

This satisfies Pythagoras' Theorem :)

For this kind of questions, first label the adjacent side, opposite side and the hypotenuse side of the triangle.

Cosine angle= adjacent/ hypotenuse

Sine angle= opposite/ hypotenuse

tangent angle= opposite/ adjacent

Then substitute the known side and angle to find the unknown side.

this would give you 25% of 450

400÷100=4.5

4.5×25=112.5

Final answer:

To find the value of x, set the expressions equal to each other and solve for x.

Explanation:

To find the value of x in the given equation, we need to set the two expressions equal to each other and solve for x. So, we have:

19x - 36 = 6x + 31

Subtracting 6x from both sides, we get:

13x - 36 = 31

Adding 36 to both sides, we get:

13x = 67

Dividing both sides by 13, we get:

x = 67/13

So the value of x is approximately 5.15.

Answer:

Part A : [tex]1621\frac{1}{3}\pi[/tex] cubic meters.

Part B : 540π cubic cm.

Part C : [tex]V = \frac{4}{3}\pi r^{3}[/tex]

Step-by-step explanation:

Part A :

The volume of the silo includes the volume of a hemisphere and a cylinder.

So, the total volume

[tex]V = \frac{2}{3}\pi r^{3} + \pi r^{2}h[/tex]

⇒ [tex]V = \frac{2}{3} \times \pi (8)^{3} + \pi (8)^{2} (20)[/tex]

⇒ [tex]V = \frac{1024}{3}\pi + 1280\pi = 1621\frac{1}{3}\pi[/tex] cubic meters. (Answer)

Part B :

The volume of the cylindrical cup with height 15 cm and base radius 6 cm is given by

[tex]V = \pi r^{2}h = \pi (6)^{2} (15) = 540\pi[/tex] cubic cm.

Therefore, Mary can put 540π cubic cm of water in the cup with out it overflowing. (Answer)

Part C :

Answer:

the answer is the first graph

Step-by-step explanation:

because the negative points are not viable

The graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a linear equation in the form of slope:

y = 5.5x

Slope of the line m = 5.5

Slope is positive, which means the line goes down to up.

We can plot the graph of the equation y = 5.5x

Option first On a coordinate plane, x-axis is numbered negative 5 to positive 5 in increments of 1, and the y-axis is numbered negative 27.5 to 27.5 in increments of 5.5. A straight line with a positive slope begins at point (0, 0) and ends at point (5, 27.5) is correct.

Thus, the graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

#SPJ2

Answer:

None of the above

Step-by-step explanation:

So in order to do this you have to plug in each answer to the equation.

Lets start with (6,0)

0 = -2(6) + 6 =     0 = -6.  This answer is wrong because its false. 0 does not equal -6.

Next answer, (1,4)

1 = -2(4) + 6 =     1 = -2   This answer is also wrong because 1 does not equal -2.

Next answer, (-2,-2)

-2 = -2(-2) + 6 =      -2 = 10   This answer is wrong as well because -2 doesn't equal 10.

This leaves us with none of the above which is true since the first 3 answers are wrong.
