The width of the prism is (2x − 2) ft, and its height is (x + 5) ft. The area of the base of the prism is (2x2 + 6x − 8) ft2.

Answers

Answer 1

Answer:

2x^2+8x-10

Step-by-step explanation:

Given data

Width= (2x -2) ft

Heigth=  (x + 5) ft

The area of the base is given as

Area= width * heigth

Area=  (2x -2)* (x + 5)

open bracket

Area= 2x^2+10x-2x-10

collect like terms

Area= 2x^2+8x-10

when finding slope the answer is always going to be rise/run so in this case,

#1 would be 1/2 (bc it goes up one and right 2)

#2 we have a rise of 3 and a run of 3 leaving our slope to be 3/3 simplified simply being 1

another trick you could use is dividing the denominator by the numerator

f(x)=x-4 is the answer i believe

Answer :

The function is  

Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

Find the coordinates of P so that P partitions segment A to B in the ratio 5:1 with A(2,
4) and B(8, 10).

Answers

Answer:

Point P has coordinates (7,9) (last choice)

Step-by-step explanation:

We are given the endpoints A(2,4) B(8,10) and the point P lying on the segment AB with the condition that P partitions it in the ratio 5:1.

This means the distances AP, PB and AB follow the conditions:

[tex]\frac{AP}{PB}=\frac{5}{1}[/tex]

AP+PB=AB

We can work with each coordinate separately. Suppose P has coordinates (x,y), thus:

[tex]x-x_a=5(x_b-x)[/tex]

[tex]x-x_a=5x_b-5x[/tex]

Adding 5x and subtracting:

[tex]6x=5x_b+x_a[/tex]

Dividing by 6:

[tex]\displaystyle x=\frac{5x_b+x_a}{6}[/tex]

Substituting:

[tex]\displaystyle x=\frac{5*8+2}{6}=\frac{42}{6}=7[/tex]

x=7

Now for the y-axis:

[tex]\displaystyle y=\frac{5y_b+y_a}{6}[/tex]

Substituting:

[tex]\displaystyle y=\frac{5*10+4}{6}=\frac{54}{6}=9[/tex]

y=9

Point P has coordinates (7,9) (last choice)
