I nee help. Can anyone help please.

Answer:

a) 15.625 cm²

b) 8 cm²

c) 50 cm²

d) 12 cm²

Step-by-step explanation:

a) area of a parallelogram = base x height

⇒ area of yellow shape = 1/2 x base x height

                                        = 1/2 x 12.5 x 2.5

                                        = 15.625 cm²

b) area of triangle = 1/2 x base x height

                              = 1/2 x 2 x 8

                              = 8 cm²

c) area of a parallelogram = base x height

area yellow parallelogram = (10 x 6) - (5 x 2) = 50 cm²

d) area of a parallelogram = base x height

⇒ area of a 1/2 parallelogram = 1/2 x base x height

⇒ area yellow shape = 1/2 x 12 x 2 = 12 cm²

Answer:

Above your sheet, they give you formulas for the rectangular prism.

Method one;

V = L x W x H

Where "L" is length, "W" is width, and "H" is height.

Method 2;

V = B x H

Where "B" is the area of the base, and "H" is the height.

Now let's apply these formula to your questions:-

(Using method 2 for most of these problems)

1. If we look for the area of the base, we can see that 2 is the width and 4 is the length, so we would need to multiply those two to get the area of the base (2 x 4) = 8.

Now the height is 3.

So we plug this into our formula,

V = B x H

V = 8 x 3

V = 24 cubic feet

2. If we look at this question, we can see that this is a cube, meaning that all lengths are the same. To make this easier, we can use method 1 and just multiply the given lengths;

V = L x W x H

V = 4 x 4 x 4

V = 64 cubic inches

3. If we look for the area of the base, we can see that 5 is the width and the length is 20, so we would need to multiply those two to get the area of the base (5 x 20) = 100.

The height is 5.

So we plug this into our formula;

V = B x H

V = 100 x 5

V = 500 cubic yards

4) If we look for the area of the base, we can see that 3.2, if i'm correct, is the width and 5.4 is the length, so we would need to multiply those two to get the area of the base (3.2 x 5.4) = 17.28.

The height is 1.9.

So we plug this into our formula;

V = B x H

V = 17.28 x 1.9

V = 32.832, 32.83 cubic centimeters

The statements which is true for a bond of par value $1,000 is that the market value includes a discount of $47. 70.

Market value is the current price of a product, company, or something consorting to the stock of the market.

It is the price which is required to buy something in the current market.

Bonds issued by Animite Energy are selling at a rate of 95.230.  This is the bond percentage of the Animite energy in the market. This means if someone wants to buy 95.230 of this company's bond, then he get $100.

Now for the 1000 bonds, the amount required is,

[tex]C=95.230\times10\\C=952.30[/tex]

Hence, for the 1000 bonds, the amount required is 952.30. Therefore, the discount will be,

[tex]d=1000-952.30\\d=47.70[/tex]

Hence, the statements which is true for a bond of par value $1,000 is that the market value includes a discount of $47. 70.

Answer:

The correct option is OPTION C.

Step-by-step explanation:

Recall that for a rhombus, the diagonals bisect the interior angles.

This means that if we are given that:

m∠DAB=160°

Then:

m∠EAB=m∠DAB/2=160/2=80°

Also, recall that the diagonals of a rhombus are perpendicular. Therefore:

m∠AEB=90°

Hence, we can have a triangle that looks like the one shown below:

Recall that the sum of angles in a triangle is 180°. Therefore, we have that:

m∠AEB+m∠ABE+m∠EAB=180°

Hence, we can calculate m∠ABE to be:

m∠ABE =180-80-90

m∠ABE=10°

The correct option is OPTION C.

Answer:

33

Step-by-step explanation:

Alright, so, let's break it down.

We know that d = negative 6 (-6)

Lets start with -5d.

Since d = -6, we have to do -5 × -6, which is 30.

So, now, we are using fractions. -6 plus 15.

(Which is, negative 6 plus 15)

That is 9. Since we are adding a negative number to a positive number, it will be the same way as 15 minus 6.

Now, we know that we are using division (due to the fraction line, we know that we are using division). Let's divide 9 into 3. That's 3, because 3 times 3 is also 9. Now, if we add 30 plus 3, we get 33, Therefore, the answer is 33.

Answer:

33

Step-by-step explanation:

-5(-6) + (-6) + 15/3

30 + -6 + 15/3

The values of a, b, and c to complete the table for the inverse of the logarithmic function is 2,1 and -2 respectively.

The Inverse of the logarithmic function is an exponential function.

The given logarithmic function is,

[tex]f(x) = \log_{0. 5}x[/tex]

The inverse of the given logarithmic function is,

[tex]f^{-1}(x) = 0.5^x.[/tex]

Put the value of x as -1 from the table attached below, to find the value of a.

[tex]f^{-1}(-1) = 0.5^{(-1)}\\f^{-1}(-1) = 2[/tex]

Similarly, put the value of x as 0 from the table attached below, to find the value of b.

[tex]f^{-1}(0) = 0.5^{(0)}\\f^{-1}(0) = 1[/tex]

Now, put the value of x as 2 from the table attached below, to find the value of c.

[tex]f^{-1}(2) = 0.5^{(2)}\\f^{-1}(2) = -2[/tex]

The solution is, The equation the line is,  y = -3x/4 -8

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have

two points (-4, -5) and (-8, -2)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>(y+5)/(x+4)=(-2+5)/(-8+4)

=>(y+5)/(x+4)= 3/ -4

=>-4y - 20 = 3x +12

=> -4y = 3x + 32

=> y = -3x/4 -8

Hence, the required equation is,   y = -3x/4 -8

Answer:

1. Over three, up three
2. Over two, up one

Step-by-step explanation:

Given the following question:

Point A = (3, 3)
Point B = (2, 1)

To find the answer, please understand where the x and y axis is located. Remember that the x is the line intersecting the y axis.

So, in order to plot point A and B, we have to remember that the first value represents x, and the second represents the y value.

(3, 3) = (x, y)
(2, 1) = (x, y)

For the first point we will move over three on the x axis, and then up three on the y axis.

For the second point we will move over two on the x axis, and then up 1 on the y axis.
