Eric has saved $18,300 toward a down payment on a house. He makes a salary of $59,750 a year. What is the maximum he could afford to borrow to buy a house? a) $90,500 b) $101,200
c) $119,500
d) $137,800

Answers

from the
well
assuming that he spends all his savings on the house and doesn't eat or spend on anything else and that he pays per year

experimient
down+other=total
18300+(59750 times years)answer
if years=1 then
tota=78050 which is not listed

if years=2 then
total=137800

that is lats choice

answe is last choice (D)
( I actually don't know since question is not clear)
D.137,800 because 59750 + 18300 is 78050   then add one more year of work 59750 and you get  137800 and you cant get anymore or you will be working forever.

assuming you mean SURFACE area

look at shape
fold it out or whateveryo yo like
we see that the faces are
4 triangles
4 rectangles in midddle
4 more triangles on other side


calculate areas
area of triangle=1/2bh
area of rectangle=bh

leftmost side
h=1.8
b=2
4*1/2*2*1.8=7.2 cm^2

middle recangles
base=3
height=2
aera=3*2=6
multply by 4 snce 4 recangles
6*4=24 cm^2

other triangles

b=2
h=2.71
total area=4*1/2*2*2.71=10.84cm^2
add them up

7.2cm^2+24cm^2+10.84cm^2=42.04cm^2

Can someone help me with this math question

Answers

Answer:

The coordinates of D' are (1,-1)

Step-by-step explanation:

The point D in the figure has co-ordinates (2,-2) as shown in the figure.

The figure is dilated by a factor of 1/2

So, multiply the coordinates of D (2,-2) by 1/2

D' = (1/2*2, 1/2*-2)

D' = (1,-1)

So, the coordinates of D' are (1,-1)

Evaluate the function below for x=2.   F(x)=2x^3-x^2-5x+6

Answers

Answer:

A Function states an equation that has only one answer for y for every x. Also, a function assigns exactly one output to each input of a specified type.

i,e y= f(x) where x represents the input variable and y represents the output value.

Given the function: F(x) = 2x^3-x^2-5x+6

Substitute the given input value of x =2 , we get;

F(2) = 2(2)^3-(2)^2-5(2)+6

F(2) = 2(8)-4-10+6

or

F(2) = 16-4-10+6

Simplify:

F(2) = 8

Therefore, the function F(x)=2x^3-x^2-5x+6 for x=2, we have F(2) =8.
f(x)=2x^3-x^2-5x+6 \ \ \ \boxed{x=2}\n \n f(2)=2*2^3-2^2-5*2+6\n \n f(2)=16-4-10+6\n \n f(2)=8
