Answer:

[tex]g=2T^2-6[/tex]

Step-by-step explanation:

To make g the subject, you have to isolate it in the form of g = (stuff)

-----------------------------------------------------------------------------------------------------

[tex]T=\sqrt{\frac{g+6}{2}}[/tex]

Square both sides:

[tex]T^2=\frac{g+6}{2}[/tex]

Multiply both sides by 2:

[tex]2T^2=g+6[/tex]

Swap Sides:

[tex]g+6=2T^2[/tex]

Subtract 6 from both sides:

[tex]g=2T^2-6[/tex]

Answer:

Since BD bisects Angle ABC, Angle ABD = Angle DBC

[tex]3x+6=7x-18[/tex]

Subtract 6 from both sides:

[tex]3x+6-6=7x-18-6[/tex]

[tex]3x=7x-24[/tex]

Subtract 7x from both sides:

[tex]3x-7x=7x-24-7x[/tex]

[tex]-4x=-24[/tex]

Divide both sides by -4:

[tex]\frac{-4x}{-4}=\frac{-24}{-4}[/tex]

[tex]x=6[/tex]

Angle [tex]ABD=3x+6=3(6)+6=18+6=24[/tex]

Angle [tex]CBD=7x-18=7(6)-18=42-18=24[/tex]

Angle [tex]ABC=ABD+CBD=24+24=48[/tex]

Answer:

m<ABD= 6

m<CBD= -18

m<ABC= -108

Answer:

Step-by-step explanation:

Mean = Sum of all data [tex]\div[/tex] Number of data

Let x be the other number.

[tex]30 =\frac{12+50+48+x}{4}[/tex]

Multiply both sides by 4:

[tex]\frac{4\left(12+50+48+x\right)}{4}=30* \:4[/tex]

[tex]x+110=120[/tex]

Subtract 110 from both sides:

[tex]x+110-110=120-110[/tex]

[tex]x=10[/tex]

Answer:

B:10

Step-by-step explanation:

Set up the equation

(12+50+48+x)/4=30

Add like terms

(110+x)/4=30

now multiply both sides by 4

(110+x)/4=30

4              4

110+x=120

Now subtract  110 from both sides

x=10

The first awnser is right because the x    doesnt have a value therefore you keep the x but you still do the problem.

the second one is right because the same  explanation for the first question but its addition and if the x had a value then you would multiply the 4 and the value of the x first then you would do the addition.

Step-by-step explanation:

(5x - 3x^2) - (5x -2)

Distribute the minus signs

(5x - 3x^2) - 5x +2

Combine like terms

-3x^2 +5x-5x+2

-3x^2+2

Answer:

7x^2 + 7

Step-by-step explanation:

So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.

Hope that explanation makes sense

Answer:

[tex]3x^{2} + 4 {x}^{2} + 7 = 7 {x}^{4} + 7[/tex]

Step-by-step explanation:

Because 3x² and 4x² are like terms, they can be added together:

3+4=7

²+²=⁴

Therefore, it will be 7x⁴.

But 7x⁴ and 7 are not like terms. So it is just 7x⁴+7

Answer:

x=-5

Step-by-step explanation:

The turning point is at x=-5 and thus is the axis of symmetry.

I think the answer is $238.

71 x $3 = $213

2 + 3 = 5

5 x $5 = $25

$213 + $25 = $238

I hope this helps.

The total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of ticket for adult = $5.00

Cost of ticket for students = $3.00

Now, Total number of students = 71

Number of parents = 3

Number of teachers = 2

So, total adults = 3 + 2 = 5

Thus, Total cost of tickets for students = 71*5 = $355

and, Total cost of tickets for adults = 5*3 = 1$5

Therefore,

Total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum = Total cost of tickets for students + Total cost of tickets for adults

⇒ Total cost of ticket for a group = $355 + $5

⇒ Total cost of ticket for a group = $360

Thus, the total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.

Step-by-step explanation:

Answer:

The square root of 32 by 3 is 5.657

Step-by-step explanation:

Answer:

Step-by-step explanation:

Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.

f(x) = 40 - 2x

For x = 0,

f(x) = 40 miles

For f(x) = 0,

0 = 40 - 2x

x = 20 minutes

This shows that helicopter traveled 40 miles in 20 minutes.

Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.

For x = 0,

f(x) = 500 miles

For f(x) = 0,

x = 100 minutes

Commercial jet traveled 500 miles in 100 minutes.

The total distance and time taken for each flight are illustrations of intercepts.

We have:

[tex]x \to[/tex] minutes

[tex]f(x) \to[/tex] miles

Helicopter

[tex]f(x) = 40 - 2x[/tex]

Set f(x) to 0, to calculate the x-intercept

[tex]0 = 40 - 2x[/tex]

Collect like terms

[tex]2x = 40[/tex]

Divide by 2

[tex]x =20[/tex]

Set x to 0, to calculate the y intercept

[tex]f(x) = 40 - 2x[/tex]

[tex]f(0) = 40 - 2 \times 0[/tex]

[tex]f(0) = 40[/tex]

This means that, the helicopter traveled 40 miles in 20 minutes

Commercial Jet

From the graph, the intercepts are:

[tex](x_1,y_1) = (100,0)[/tex] --- the x-intercept

[tex](x_2,y_2) = (0,500)[/tex] --- the y-intercept

This means that, the commercial jet traveled 500 miles in 100 minutes
