Hi, there!

Option A. 3.2 x 10²

Step-by-step explanation:

320 written in scientific notation is 3.2 × 102.

Answer: f(x)= 3x + 10 and g(x)= 2x - 4

(f+g)(x)= 3x + 10 + 2x - 4

3x + 2x + 6

5x + 6

Answer:

associative property of addition !!

Step-by-step explanation:

this is because you are ASSOCIATING the two numbers together

think of it like this

in a trio friendship there could be two friends that are closer

the 8 and the 10 in the second half of the equation are closer

BUT in the first half the 3 and the 8 are closer too

hope that made sense lol

To convert m/s to mi/min we have to find conversion factor first

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let’s put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min

Answer: V = 1.118 ∙ 107 mi/min

Hope u have a good day of learning

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let's put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min

Answer: V = 1.118 - 107 mi/min

Answer:8

Step-by-step explanation:

3/4n +2=8

3/4n=8-2

n =( 6)/(3/4)

24/3=8

Point (9, 6) would be on the inverse of this function so option (D) will be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the sets of coordinates of a function.

An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.

For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.

Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.

Hence "Point (9, 6) would be on the inverse of this function".

Answer:

x = 1

Step-by-step explanation:

[tex] {5}^{2x} - 2( {5}^{x} ) - 15 = 0[/tex]

[tex]( {5}^{x} {)}^{2} - 2 \times {5}^{x} - 15 = 0[/tex]

[tex] {t}^{2} - 2t - 15 = 0[/tex]

[tex] {5}^{x} t = - 3 \: \: .5[/tex]

[tex] {5}^{x} = 5[/tex]

[tex]x = 1[/tex]

Answer:

477.09 mi/da

Step-by-step explanation:

If student must use conversion given, 3.28ft = 1m, then the following works:

32km/hr = ______mi/da       1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft

32km/hr  x  24hr/day  x  1000m/1km  x  3.28ft/1m  x  1mi/5280ft  = 477.09mi/da

If student can use 1km = 0.62mi, some steps can be skipped.

C

Step-by-step explanation:

[tex] (6^{-4} \times 8^{-7})^{-9} = [/tex]

[tex] = 6^{36} \times 8^{63} [/tex]

Answer: C

Answer:

129

Step-by-step explanation:

Every angle would be similar to each other with having only TWO different degrees...

Each line ( <----------------------> ) equals 180 (never 360, b/c that would be a circle)

Now with you only having 51 as a degree, you need to do 180-51 which gives you 129, with that given, this tells you number 1 and 3 is both 129, and angle 2 is 51.

Answer:

D. 8 1/3

Step-by-step explanation:

solve each traingle

the bottom one:

the line that cut the traingle, made each angle is 90°

10/sin90° = 5/sin?

sin? = 5sin90°/10 = 1/2

the angle is sin^-1 (1/2) = 30°   ⇒

10/sin90° = ?/sin60°

? = 10sin60°/sin90° = 5√3   ⇒

12/sin90° = 5√3/sin?

sin? = 5√3 sin90°/12 = 5√3 /12

? ≈46°

180 - (46+90) = 44°   ⇒

x/sin44° = 12/sin90°

x = 12sin44°/sin90° = 8.3

x = 8 1/3

Answer:

  x < 2   or   (-∞, 2)

Step-by-step explanation:

(f -g)(x) = (x -3) -(-0.5x) = 1.5x -3

We want to find (f -g)(x) < 0, so we have ...

  1.5x -3 < 0

  1.5x < 3 . . . . . . . add 3

  x < 2 . . . . . . . . . .divide by 1.5

The function (f -g)(x) is negative on the interval x < 2.

Answer:

(72, 297)

Step-by-step explanation:

1/3v = (-12/3, 15/3) = (-4, 5)

4w = (3(4), 7(4)) = (12, 28)

The sum of these two is (12 - 4, 5 + 28) = (8, 33)

9 times this vector is (8(9), 33(9)) = (72, 297)

Step-by-step explanation:

option A is the right answer

Answer:

C

Step-by-step explanation:

They are complementary which means they add to 90. I take it that the c is a typo and you meant x

6x + 3 + 4x + 7 = 90                  Combine like terms.

10x + 10 = 90                             Subtract 10 from both sides

10x = 90 - 10

10x = 80                                    Divide by 20

x = 80/10

x = 8
