Answer:

42cm²

Step-by-step explanation:

because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²

Answer:

Step-by-step explanation:

Sum of interior angles of polygon = (n -2) * 180

Sum of interior angles of hexagon =  (6-2)*180 = 4* 180 = 720

4x + 5x +6x +7x + 8x +9x = 180

39x = 180

x = 180/39

x=4.61

Smallest angle = 4x = 4*4.61  = 18.44

Answer:

x(x + 1)(x - 1)

Thus the answer is (b)

The solutions to the given quadratic equation are +4 and -4. Therefore, the option B is the correct answer.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic equation is x²-16=0.

Now, x²=16

x=±√16

x=±4

x=+4 or x=-4

Therefore, the option B is the correct answer.

Answer:

42.42in³

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

Step one

We know that the volume of a cone is

V= 1/3πr²h

Given data

Diameter d= 6 inches

Radius r= diameter/2= 6/2= 3 inches

Height h = 4.5 inches

Step two

Substituting our given data we have

Volume = 1/3*3.142*3²*4.5

V= 1/3*3.142*9*4.5

V= 127.251/3

V= 42.42in³

Answer:

D

Step-by-step explanation:

a. The median, or line in the middle, is the same for both

b. This is the start to end of the box. For the top one, we have 39-33=6. For the bottom one, we have 36-30=6. These are the same.

c. The range is the highest minus the lowest value. For the top one, this is 41-31=10. For the bottom one, this is 38-28=10. These are the same.

This leaves D as our answer

Answer:Find the domain of y = log(x + 3)

Logarithms can only be taken for positive numbers. So you must have

x + 3 > 0

x > – 3          ✔

So the domain of the function is

D = {x ∈ R:  x > – 3}

or using the interval notation

D = (– 3, +∞)

AB = 4.5

Step-by-step explanation:

We can cross multiply the sides in order to find the length of AB. Make sure you don't go diagonal, so you can't do 3/6. You can do 3/4 and 3/x, then match it to the same pattern.

This is the one I chose...

[tex]\frac{4}{3} =\frac{6}{x}[/tex]

Notice how I put them in the same order.

Now we can cross multiply...

[tex]4*x[/tex]

= 4x

[tex]6*3[/tex]

= 18

[tex]4x=18[/tex]

Divide by 4.

x = 4.5

The length of AB is 4.5.

Answer:

3.33times 10^7 because when it is possible to substract 2.24times10^5 from it

Answer:

Answer: A) 3.33 x 10⁷

Step-by-step explanation:

A is the correct answer because you're adding 7 to the left. Whereas for B, it's only 5 times, and the number is less than 3.33.

3.33 ⇒ 33.3 ⇒ 333 ⇒ 3330 ⇒ 33300 ⇒ 333000 ⇒ 3330000 ⇒ 33300000

2.34 ⇒  23.4 ⇒  234 ⇒  2340 ⇒  23400 ⇒  234000

Answer:

[tex] (x - 3)^{2} + { (y + 2)^{2} = 49[/tex]

Step-by-step explanation:

Center of the circle = (3, - 2) = (h, k)

Therefore, h = 3, k = - 2

Radius r = 7

Equation of circle in centre radius form is given as:

[tex](x - h)^{2} + {(y - k)}^{2} = {r}^{2} \\ \therefore \: (x - 3)^{2} + { \{y - ( - 2) \}}^{2} = {7}^{2} \\ \red{ \boxed{ \bold{\therefore \: (x - 3)^{2} + (y + 2)^{2} = 49}}}[/tex]
