Answer:

Absolute minimum / vertex = (5/6,-133/12)

Step-by-step explanation:

Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)

Multiply the average by number of people:

84.5 x 4 = 338

This means the total of the 4 grades need to equal 338

To find Jonathan’s grade subtract the other 3 grades from 338:

338 - 86 - 92 -70 = 90

Jonathan’s grade was 90

Answer:

246 or 468.

Step-by-step explanation:

The only possible even digits are 2, 4, 6, and 8 (0 is neither even nor odd).

Therefore, your possible numbers are 246 and 468.

(0, infinity)

Answer:

c

Step-by-step explanation:

Answer:

using trigonometric ratio sin, which is

sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse

sin 40°= x/9

multiply both sides of this by 9 to remove the 9 in the side we have x, we will have

sin 40°/9=x

sin° 40 =0.7451

so x= 0.7451/9

which is

x= 0.0827888888

to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Step-by-step explanation:

Answer:

First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way

Step-by-step explanation:

Considering speed of Noha = 4miles per hour

and speed of andrew = 2 miles/hour

The distance between Noha and andrew = 15 miles

Case 1: when they are travelling towards each other( opposite direction)

Then their relative speed becomes = 4+2 = 6miles/hour

Time taken to meet = Distance/relative speed = 15/6 = 2.5 hours

Case2: When they are travelling same direction

Then their relative speed becomes = 4-2 = 2 miles/hour

Time taken to meet = Distance/ relative speed = 15/2 = 7.5 hours

Answer:

27

Step-by-step explanation:

Givens

b1 = 13

b2 = ?

h = 6

Area = 120

Formula

Area = (b1 + b2) * h/2         Multiply by 2

2Area = (b1 + b2)*h           Divide by h

2Area/h = b1 + b2              Subtract b1 from both sides

2Area/h - b1 = b2

Solution

2*120 / 6 - 13 = b2

40 - 13 = b2

b2 = 27

It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

1 3/9 is da answerrr

Answer:

6

Step-by-step explanation:

The rate can be calculated as follows

x + x -16

2x-16

(2x-16)×5

10x - 80= 800

10x = 300-80

10x, = 220

x = 220/10

= 22

22-16

= 6 mph

Hence the rate of the west bound tsin is 6mph

Answer:

option 3

Step-by-step explanation:

Answer:

(c) and (e)

Step-by-step explanation:

Given

[tex]Pr = \frac{2}{3}[/tex]

Required

Which 2 options can be used to simulate the given probability.

The two options are (c) and (e)

The proof is as follows;

Option (c)

We have:

[tex]Rolls = 7[/tex]

A cube has 6 faces. So:

[tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(S)=6[/tex]

The probability of getting ones, twos, threes, and fours is:

[tex]Pr = \frac{n(1,2,3,4)}{n(S)}[/tex]

In: [tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(1,2,3,4) = 4[/tex]

So:

[tex]Pr = \frac{4}{6}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

Option (e)

We have:

[tex]White = 10[/tex]

[tex]Red = 5[/tex]

[tex]Count = 7[/tex]

Record the probability of white.

This is calculated as:

[tex]Pr = \frac{White}{Total}[/tex]

[tex]Pr = \frac{White}{White + Red}[/tex]

[tex]Pr = \frac{10}{10+5}[/tex]

[tex]Pr = \frac{10}{15}[/tex]

Simplify

[tex]Pr = \frac{2}{3}[/tex]

__

I like to put the variable in the numerator of a proportion. Here, we can write it as ...

  t/12 = 45/90

Multiplying by 12 gives ...

  t = 12(45/90) = 12(1/2) = 6

It will take Darin 6 hours to mow 12 lawns.
