What as a numerical expression four times the sum of 5 and 6

Answer:

A)   Θ = 2A/r²

Step-by-step explanation:

A = Θr²/2

(Multiple both sides by 2)

2A = Θr²

(Divide both sides by r²)

2A/r² = Θ

Answer:

{ - 9, - 7, - 3, - 1 }

Step-by-step explanation:

To obtain the range substitute the values of x from the domain into f(x)

f(- 2) = - 2(- 2) - 5 = 4 - 5 = - 1

f(- 1) = - 2(- 1) - 5 = 2 - 5 = - 3

f(1) = - 2(1) - 5 = - 2 - 5 = - 7

f(2) = - 2(2) - 5 = - 4 - 5 = - 9

range is { - 9, - 7, - 3, - 1 }

Answer:

16[tex]\pi[/tex]

Step-by-step explanation:

we know that the formula for finding area of circle is A=[tex]\pi[/tex]r^2. and circumference of circle can be calculated by c=2[tex]\pi[/tex]r.

first we need find radius from circumference formula and put in area formula to get the desired result.

for radius, r=c/2[tex]\pi[/tex] =8[tex]\pi[/tex]/2[tex]\pi[/tex] we get 4. now put in area formula as shown above.

we get , A=[tex]\pi[/tex]*(4)^2 =[tex]\pi[/tex]*4*4 =16[tex]\pi[/tex]

Answer:

45.75

Step-by-step explanation:

183/4=45.75.

Answer:

=45.75

Step-by-step explanation:

This is a fraction equal to

183 ÷ 4

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 4

182

÷ 4

4

÷ 4

=

45.75/1  

=

45.75  

= 45.75  

Option D: [tex](3,14)[/tex] is the point of intersection of the two lines.

Explanation:

The two equations are [tex]y-6 x=-4[/tex] and [tex]y-2 x=8[/tex]

We need to find the point of intersection of the two lines.

Thus, let us solve the equation by substitution method.

From the equation [tex]y-6 x=-4[/tex], we shall determine the value of y, by adding both sides of the equation by 6x.

Hence, we have, [tex]y=6x-4[/tex]

Now, substituting [tex]y=6x-4[/tex] in the equation [tex]y-2 x=8[/tex] , we get,

[tex]6x-4-2 x=8[/tex]

       [tex]4x-4=8[/tex]

             [tex]4x=12[/tex]

               [tex]x=3[/tex]

Substituting [tex]x=3[/tex] in the equation [tex]y-6 x=-4[/tex], we get,

[tex]y-2 (3)=8[/tex]

   [tex]y-6=8[/tex]

         [tex]y=14[/tex]

Thus, the point of intersection of the two lines is [tex](3,14)[/tex]

Therefore, Option D is the correct answer.

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothegm. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothegm = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Step-by-step explanation:

First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.

Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.

Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.

Answer:

The required distance is 17.34 meters.

Step-by-step explanation:

The lengths of the two wires are 12 meters and 16 meters. and the angle between the wires is 75°.

Now, we have to calculate the distance between the wires on the ground.

Therefore, we have to calculate the length of the side which is the opposite side of angle 75° of the triangle formed by the wires and the ground.

Applying the formula of properties of the triangle, if the length required is x, then

[tex]\cos 75^{\circ} = \frac{12^{2} + 16^{2} - x^{2}}{2 \times 12 \times 16}[/tex]

⇒ 99.38 = 144 + 256 - x²

⇒ x = 17.34 meters. (Answer)

Answer:

b. 4

Step-by-step explanation:

Given f(x) = 4x - 4 and g(x) = x - 1, we can find (f/g)(x) by dividing f(x) by g(x):

(f/g)(x) = (4x - 4)/(x - 1)

Now, substituting x = -4 into the expression

(f/g)(-4) = (4*(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4

Therefore, the correct answer is b. 4.

Given the function g(x) = x - 1, let's solve (f/g)(-4) using the function f(x) = 4x - 4.

To find (f/g)(-4), we need to evaluate the expression (f(x)/g(x)) at x = -4.

First, let's find the value of f(x)/g(x) for any x:

(f/g)(x) = f(x)/g(x) = (4x - 4)/(x - 1)

Now, substituting x = -4 into the expression:

(f/g)(-4) = (4(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4

Therefore, the correct answer is b. 4.

Given here:

a= 2 => f(a) = 2

b=6 => f(b) = 2

Substitute all the values into the function, we have:

Answer:

25.4 feet tall

Step-by-step explanation:

254 divided by 10 equals 25.4

The height of the apple tree that you expect an apple tree to be ​25.4 feet.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A coast redwood tree is about 10 times as tall as an apple tree.

Let 'x' and 'y' be the height of redwood and apple trees. Then the equation is given as,

y = x / 10

One of the tallest coast redwoods even measured 254 feet tall. Then we have

y = 254 / 10

y = 25.4 feet

The height of the apple tree that you expect an apple tree to be ​25.4 feet.
