f(x) = 3x2 + 2 and g(x) = x2 – 9,

Answer:

x=1.65

Step-by-step explanation:

First switch sides

4x-8=3.6-2-3

Then subtract 3.6 - 2 - 3

4x-8=-1.4

Add 8 to both sides

4x-8+8=-1.4+8

simplify

4x=6.6

Divide both sides by 4

4x/4 - 6.6/4

The simplify again

x=1.65

Step-by-step explanation:

Volume = 13in * 9in * 2in = 234in³.

Answer:

234 inches³

Step-by-step explanation:

Formula for volume of a prism = [tex]L \times W \times H[/tex] (L = length, W = width, H = height)

[tex]\therefore[/tex] volume for baking dish = 13 × 9 × 2

                                          = 234 inches³

Answer

952.49feet

Step-by-step explanation:

This set up will be a right angled triangle

Height = opposite side = 425foot

Length of wire = hypotenuse= x

Angle of elevation= 26.5°

Using the SOH identity

Sin 26.5 = opp/hyp

Sin26.5 = 425/x

x = 425/sin26.5

x =425/0.4462

x = 952.49feet

Hence the length of the wire is 952.49feet

A right triangle has two sides of the same length and the two same sides create a 90 degree angle.

Answer:

You need to insert different x values and plot the point. So let's say x=1 the answer would be 10 and for 2 it would be 17

Answer with what

Step-by-step explanation:

Answer:

$45

Step-by-step explanation:

so where the line intercepts the 2 hours is $45, and to find the .25 hours we take the $20 for working one hour and divide that by four, because .25 is 1/4 of an hour. so 20/4 is five. then you add 5 to 40 and we get $45 for work 2.25 hours. hope that helped

Answer: I would think the answer is C

Step-by-step explanation: 4 divided by 15 is 0.26666667

Answer:

4.8 hours

Step-by-step explanation:

Step one:

given data

The total distance= 220 miles

The velocity of the train= 3/4 mile per minute

Required

The time of travel

Step two:

we know that

velocity= distance/time

velocity= 220/3/4

let us multiply the numerator (220) by the inverse of the denominator(4/3)

velocity =220*4/3

velocity= 880/3

velocity= 293.3 minutes

in hours

= 293.3/60

= 4.8 hours

Answer:

Step-by-step explanation:

Answer:

P = (18a+10b+13) cm

Step-by-step explanation:

Given that,

A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.

We need to find an expression that represents the perimeter of the triangle.

Perimeter = sum of all sides

P = (10a+9) + (8a-3) + (10b+7)

Taking like terms together,

P = (10a+8a)+10b+(9-3+7)

= 18a+10b+13

Hence, the epresssion for the perimeter is (18a+10b+13) cm.

Answer:

130 students do not ride the bus to school.

Step-by-step explanation:

520 * .75 = 390

390 students ride the bus to school.

520-390=130

130 students do NOT ride the bus to school.

Answer:

Choice 3: [tex]\sqrt{2}[/tex]

Step-by-step explanation:

The first thing is that you have to break the √10. The only way you can break it is to make it into a 5 and a √2. So now it should look like this [tex]\frac{5}{5\sqrt{2}}[/tex]. Then we will divide the 5 by 5 and that'll become 1, so we are left with a [tex]\sqrt{2}[/tex] and that's it.

Step-by-step explanation:

y = -2x² + 9x - 11 (2 complex solutions)

y = 3x² - 6x + 3 (1 distinct real solution)

y = -x² - 4x + 7 (2 real solutions)

Answer:

A. Juan wins the race

B. At about 7 minutes J(t )= A(t)

C. 2 minutes

Step-by-step explanation:

A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio

B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.

C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes

Answer:

-8° OR 52°

Step-by-step explanation:

Remember 22.

Now, you'll need to take 12 PM and see how many hours it is from 6 AM to 12 PM noon: 6-7, 7-8, 8-9, 9-10, 10-11, 11-12. We have 6 hours from 6 AM to 12 PM.

The problem gives us the average number of degrees it changed: 5. Since it doesn't specify HOW it changed, there are 2 answers.

In order to find the number of degrees it changed, we have to take the hours times the amount given, or in this case, 6 x 5 which equals 30.

Now that we know the fluxation number, we can either add or subtract 30 from the degrees given at noon.

So, 22 - 30 = -8 AND 22 + 30 = 50.

I hope that helps! :)
