Answer:

y = 4 $(2)^{x}$

Step-by-step explanation:

An exponential function in standard form is

y = a $b^{x}$

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = a $b^{0}$ [ $b^{0}$ = 1 ], so

a = 4

y = 4 $b^{x}$

Using (1, 8 ), then

8 = 4 $b^{1}$ = 4b ( divide both sides by 4 )

b = 2

y = 4 $(2)^{x}$ ← exponential equation

The total length of wires a b and c is 445 cm wire a is 45 cm longer then wire b and wire b is half as long as wire c how long i

Oksana_A [137]

Answer:

$a = 145\ cm$

Step-by-step explanation:

Given

$a + b + c = 445$

$a = 45 + b$

$b = \frac{1}{2}c$

Required

Determine the length of a

Solve for c in $b = \frac{1}{2}c$

$2 * b = \frac{1}{2}c * 2$

$2b = c$

$c = 2b$

Substitute $c = 2b$ and $a = 45 + b$ in $a + b + c = 445$

$a + b + c = 445$

$45 + b + b + 2b = 445$

$45 + 4b = 445$

Solve for 4b

$4b = 445 - 45$

$4b = 400$

Solve for b

$b = 400/4$

$b = 100$

Recall that: $a = 45 + b$

$a=45+100$

$a = 145\ cm$

Answer:

(2.5, 2.5)

Step-by-step explanation:

Coordinates of midpoint

$= \bigg( \frac{ - 2 + 7}{2}, \: \: \frac{6 - 1}{2} \bigg) \\ \\ = \bigg( \frac{5}{2}, \: \: \frac{5}{2} \bigg) \\ \\ = ( 2.5, \: \: 2.5 )$

The vertices of a triangle are located at X(-2,-1), Y(2,5) and Z(4,3). What is the perimeter of this triangle?

Lana71 [14]

If you plot the points you will find you have to use the distance formula. Pick out 2 pairs label them (x1,y1) (x2,y2) then plug it into the distance formula. The repeat for the other sides. So you should get (2,5) (4,3) plug into distance formula what is get it distance between those two points, then (4,3) (-2,-1) plug into distance formula to get an answer, lastly (-2,-1) (2,5) plug in. Now you have three answers add all together and here is your perimeter of a triangle.

Aubrey finished 2/9 of a project on Monday and 1/4 of the project of Tuesday. How much of the project has Aubrey completed?

riadik2000 [5.3K]

Answer:

17/36

Step-by-step explanation:

We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36
