-Please explain the process. Thanks!

Answer:

y = 153/11

Step-by-step explanation:

To find the equation, First step is to find the slope which we can use in the formula and then we will find the equation using the specific formula...

[tex] \boxed{ \sf \:m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} }[/tex]

[tex] \tt \to \: m = \frac{ - 2-( - 5)}{ - 8 -(- 4)} [/tex]

[tex] \tt \to \: m = \frac{ -2+5}{ -8+4} [/tex]

[tex] \tt \to \: m = - \frac{3}{4} [/tex]

[tex] \boxed{ \sf \:y - y_{1} = m(x - x_{1}) }[/tex]

[tex] \tt \nrightarrow \: y - ( - 5) = - \frac{3}{4} (x - ( - 4))[/tex]

[tex] \tt \nrightarrow \: y + 5 = - \frac{3}{4} (x + 4)[/tex]

[tex] \tt \nrightarrow \: y + 5 = - \frac{3}{4} x - 3[/tex]

[tex] \tt \nrightarrow \: y = - \frac{3}{4} x - 3 - 5[/tex]

[tex] \bf\nrightarrow \: y = - \frac{3}{4} x - 8[/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: 65.94

Step-by-step explanation:

Answer:

A B and C are correct

Step-by-step explanation:

4 yards = 12 feet = 12x12 = 144 inches

A is correct since 15 feet > 12 feet

B is correct since 150 inches > 144 inches

C is correct since 3 yards + 4 feet = 4 yards and 1 foot > 4 yards

D  is incorrect since 3 feet + 15 inches is 4 feet and 3 inches < 12 feet

E is incorrect since 10 feet + 11 inches < 12 feet

Answer:

she forgot the exponent on 3.5^3

Step-by-step explanation:

10 x 3.5^3 = 428.7428.75 u^3

The term "dilation" refers to a transformation. The volume of the dilated cube is 428.75 in³.

The term "dilation" refers to a transformation that is used to downsize an item. Dilation is a technique for making items appear bigger or smaller. The picture produced by this transformation is identical to the original shape.

As it is given that the volume of the cube is 10 cubic inches, therefore, the side of the cube is,

[tex]\text{Volume of the cube} = a^3\\\\ 10 = a^3\\\\a =\sqrt[3]{10}[/tex]

Now, we know that dilation always applies to dimensions, therefore the new dimension of the dilated cube will be,

[tex]\text{Side of the dilated cube} = \sqrt[3]{10} \times 3.5\rm\ in[/tex]

Further, the volume of the dilated cube can be written as,

[tex]\rm \text{Volume of the Dilated cube} = Side^3\\\\[/tex]

                                           [tex]= (\sqrt[3]{10} \times 3.5)^3\\\\ = (\sqrt[3]{10})^3 \times (3.5^3)\\\\= 10 \times 3.5^3\\\\= 10 \times 42.875\\\\= 428.75\rm\ in^3[/tex]

A.) The mistake that Kiran made is that she didn't take the cube of the scale factor.

B.) The volume of the dilated cube is 428.75 in³.

Answer:

382 x m= 249 divided by 110

Step-by-step explanation:

:)

Answer:

249= 382m-110

Step-by-step explanation:

The amount each boy receives from the R2100 is R420, R700 and R980 respectively

Total amount = R2100

Ratio = 3 : 5 : 7

Total ratio = 3 + 5 + 7

= 15

First boy = 3/15 × 2100

= 0.2 × 2100

= R420

Second boy = 5/15 × 2100

= 0.33333333333333 × 2100

= R700

Third boy = 7/15 × 2100

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:two real number solutions

Step-by-step explanation:

Answer:

$69

Step-by-step explanation:

First, we want to focus on the first $300

Multiply 300 by 0.05 to get the commission

300 x 0.05 = 15

Now, we solve for the first 300, let's solve for the remaining sales, which is 600 because 900 - 300 = 600

Multiply 600 by 0.09

600 x 0.09 = 54

Add the two sales commission numbers together

15 + 54 = 69

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:

volume is 1570 cm³

mass is 12560 g

Step-by-step explanation:

1m = 100 cm

the volume is :

1/4 x [tex]\pi[/tex] x 6² x 100 - 1/4 x [tex]\pi[/tex] x 4² x 100

= 900 [tex]\pi[/tex] - 400 [tex]\pi[/tex]              { v = 1/4 [tex]\pi[/tex] d²h }

= 500 [tex]\pi[/tex]

= 500 x 3.14

= 1570 cm³

the mass of the pipe is:

1570 x 8 = 12560 grams

To find the volume of square pyramid, We use the formula that given below.

[tex] {x}^{2} \times \frac{y}{3} [/tex]

where x is base and y is height. So, let's substitute the values.

[tex] {10}^{2} \times \frac{18}{3} [/tex]

It gives

[tex]600 {cm}^{3} [/tex]

‎ㅤ‎ㅤ‎ㅤ~Volume of the given square pyramid is 600cm³

‎ㅤ

Volume of square pyramid is given by:

[tex] \qquad\maltese\quad{\pmb{ \sf { V = \dfrac{1}{3} ( base\:area)\times height}}}[/tex]

Here, we have:

[tex] \quad\dashrightarrow\quad \sf {V = \dfrac{1}{3}\times 10\times 10\times 18 }[/tex]

[tex] \quad \dashrightarrow \quad \sf {V =\cancel{\dfrac{1800}{3} } }[/tex]

[tex] \quad \dashrightarrow \quad \sf {V = 600cm^3 }[/tex]

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]

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