2) Which of the following tables represents an exponential function?

Please help !!

Answer:

y= -3/2X + 2

Step-by-step explanation:

we get the gradient by picking any two points from the graph( it a linear graph)

using the point:

(x,y)= (-2,5) , (4,-4)

using M= (y2-y1)/x2-x1)

we get our gradient to be -9/6 which is

-3/2

using the equation of a straight line graph which is

y-y1=m(x-x1) and the point (4,-4)

we get

y-(-4)=-3/2(x-4)

----> y+4= -3/2x + 6

make y subject of the formula to take the form

y=mx+c

we get :

y=-3/2x + 2

Answer: 414628192

Step-by-step explanation: ok, so take 5+5=10

10+ 6355334= 6355344 + 64= 6355408

then do  463454432/2 which = 231727216 then

646355408-231727216=  414628192

Answer:

The radious would be 2.26

Step-by-step explanation:

Answer:

r = 2.26 ft

Step-by-step explanation:

v = πr²h

80 = πr²(5)

Divide both sides by

16 = πr²

Divide both sides by π (using 3.14 )

5.0955414013 = r²

Take the square root of both sides

r = 2.2573305919

Rounded

r = 2.26 ft

Step-by-step explanation:

Answer:

Step-by-step explanation:

A median bisects the side it intersects with, so the first step is to bisect FG.

Set the compass slightly larger than half of FG.

Put the point on F and draw a half circle that intersects FG and faces G.

Put the point on G and draw a half circle that intersects FG and faces F.

Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.

Connect the midpoint with E, and the connecting line is the median.

Answer:

57º

Step-by-step explanation:

A triangle equals 180º so to find x, just subtract the other angles from 180

180 - 39 - 84 = 57

Step-by-step explanation:

x+39+84=180 (being sum of angle of triangle is 180)

x+123=180

x=57

Answer:

81 un²

Step-by-step explanation:

9 · 7 = 63 un²

(b · h) ÷ 2

(5 · 4) ÷ 2 = 10 un²

(4 · 4) ÷ 2 = 8 un²

8 un² + 10 un² + 63 un²

81 un²

Answer:

81 un^2

Step-by-step explanation:

Find area of the rectangle. 9 x 7 = 63

Find area of the triangle. 9 x 4 = 36/2=18

63 + 18 = 81

Answer:

Component Form: v = <-1,6>

Magnitude of v: ||v|| = √37

Direction of v: θv = 100° (to the nearest degree)

Step-by-step explanation:

Component Form: v = <(5-6),(3-(-3))> = <-1,6>

Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37

Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.

Answer:

a=12 b=9

Step-by-step explanation:

u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you

a+3/4a=21

a=4/4a

4/4a+3/4a=21

7/4a=21

4/7(7/4a=21)

a=12

plug in 12 for a in either equation

b=3/4*12

b=9

(21=12+b) -12

9=b

Answer:

96

Step-by-step explanation:

once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.

x=35

Step-by-step explanation:

Answer: The last option has no solution.

1. ) The solution is 1/2

2) The solution is  -17/27

3) The solution is infinitely many solutions.

4) There is no solution because the answer solved and simplified comes out to be 17= -10; this is impossible so there is no solution

Answer:

5(2.2y + 3.4) = 5(y - 2) + 6y

Step-by-step explanation:

In order to answer this question, one must solve each of the equations until one has reached a conclusion that the parameter (y) has no solution in the given circumstance.

Equation 1

13y + 2 - 2y = 10y + 3 - y

Simplify, combine like terms;

11y + 2 = 9y + 3

Inverse operations,

11y + 2 = 9y + 3

-9y

2y + 2 = 3

-2

2y = 1

/2

y = 0.5

Equation 2

9(3y + 7) - 2 = 3(-9y + 9)

Distribute, multiply every term inside the parenthesis by the term outside of it;

(9)(3y) + (9)(7) - 2 = (3)(-9y) + (3)(9)

Simplify,

27y + 63 - 2 = -27y + 27

27y + 61 = -27y + 27

Inverse operations,

27y + 61 = -27y + 27

+27y

54y + 61 = 27

-61

54y = 34

/54

y = [tex]\frac{17}{27}[/tex]

Equation 3

32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1

Simplify, combine like terms;

34.5y - 5.1 = 34.5y - 51

As one can see, this equation is an identity, meaning that any value can be substituted into the parameter (y) to produce a true result.

Equation 4

5(2.2y + 3.4) = 5(y - 2) + 6y

Distribute, multiply every term in the parenthesis by the term outside of it;

(5)(2.2y) + (5)(3.4) = (5)(y) + (5)(-2) + 6y

Simplify,

11y + 17 = 5y - 10 + 6y

11y + 17 = 11y - 10

Inverse operations,

11y + 17 = 11y - 10

-11y

17 = -10

One can see that this equation produces a false result since it is common knowledge that (17) cannot equal (-10). Therefore, this equation has no solutions.

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

im missing 50 cents somewhere its wrong but close i think sorry

The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.

Total = $37.75

Amount left = $4.00

let

37.75 = p + b + s + 4

37.75 - 4 = p + 1/6s + 3/4p

33.75 = 1/6s + 1 3/4p

33.75 = 1/6(3/4p) + 1 3/4p

33.75 = 3/24p + 7/4p

33.75 = 3+42 / 24p

33.75 = 45/24p

p = 33.75 ÷ 45/24

= 33.75 × 24/45

= 810/45

p = $18

substitute into

s = 3/4p

= 3/4 × 18

= 54/4

s = $13.5

b = 1/6s

b = 1/6 × 13.5

b = 13.5/6

b = $2.25
