what is the following sum 4(5vx^2y)+3(5vx^2y)
i don’t know if that answer is right

Answer:

A: 120

Step-by-step explanation:

5! means 5 factorial

the factorial of a number is the number times every whole number until 1

in this case,

5 * 4 * 3 * 2 * 1

5 * 4 = 20 , 3 * 2 * 1 = 6

20 * 6 = 120 (option A)

Answer:

The answer is

[tex]c = \frac{3m + 5k}{2} [/tex]

Step-by-step explanation:

You have to move all the unrelated terms to the other side :

[tex]3m = 2c - 5k[/tex]

[tex]3m + 5k = 2c[/tex]

[tex]2c = 3m + 5k[/tex]

Next you have to divide it by 2 :

[tex]c = \frac{3m + 5k}{2} [/tex]

So, let's start off with h

The expression needs to be '3 more than h'

This can be written as:

h + 3

The expression also needs to be 'five times' this value

This can be written as:

slope = 1/2,  y intercept = 3

==============================================================

Work Shown:

Pick any two points you want on the line.

I'll pick the two points (0,3) which is the y intercept and also the point (2,4).

------

Find the slope of the line through (x1,y1) = (0,3) and (x2,y2) = (2,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 3)/(2 - 0)

m = 1/2 is the slope

slope = rise/run = 1/2

rise/run = 1/2 means rise = 1 and run = 2.

This means we go up 1 unit each time we move to the right 2 units.

-----

Since the slope is m = 1/2 and the y intercept is b = 3, we can say

y = mx+b

y = (1/2)x+3

this is the same as y = 0.5x+3 since 1/2 = 0.5

Answer:

Step-by-step explanation:

16

Answer:

1/2

Step-by-step explanation:

For each two units that this line moves to the right, it rises one. This means that it has a slope of 1/2. Hope this helps!

Answer:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Vertex = (4, -3)

Graph in the image attached, additional points:

(2, -11), (3, -5), (5, -5), (6, -11)

Step-by-step explanation:

The vertex of f(x) can be found using the formula:

[tex]x_{vertex} = -b/2a[/tex]

[tex]x_{vertex} = -16 / (-4)[/tex]

[tex]x_{vertex} = 4[/tex]

to find y_vertex, we use x_vertex in f(x):

[tex]f(x_{vertex}) = -2 * 4^2 + 16*4 - 35[/tex]

[tex]f(x_{vertex}) = -3[/tex]

So the vertex is (4, -3)

To write the function in the form [tex]f(x)=a(x-h)^2+k[/tex], we just need to calculate h = -b/2a and then find k:

[tex]h = -b/2a = -16/(-4) = 4[/tex]

[tex]f(x) = -2(x - 4)^2 + k = -2(x^2 - 8x + 16) + k = -2x^2 + 16x - 32 + k[/tex]

Comparing both forms of f(x), we have:

[tex]-32 + k = -35[/tex]

[tex]k = -3[/tex]

So we have:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Now let's find the four additional points.

Two points to the left: x = 3 and x = 2

[tex]f(3) = -2 * 3^2 + 16*3 - 35 = -5[/tex]

[tex]f(2) = -2 * 2^2 + 16*2 - 35 = -11[/tex]

Two points to the right: x = 5 and x = 6

[tex]f(5) = -2 * 5^2 + 16*5 - 35 = -5[/tex]

[tex]f(6) = -2 * 6^2 + 16*6 - 35 = -11[/tex]

Answer:

x² + x - 8

Step-by-step explanation:

(f . g)(x) is same with (f(g(x))

so insert the g(x) equation into f(x) and change the x on it

f(g(x)) = g(x) - 2

f(g(x)) = (x² + x - 6) - 2 = x² + x - 6 - 2 = x² + x -8

so

(f.g)(x) is x² + x - 8

Answer: the sum of their measures is 180 degrees

Step-by-step explanation:

I just got it right

The angles R T S and Q T P are vertically opposite angles. So that they always have equal measures.

In given circle, T is center of circle .

and RP and SQ are diameter of circle which are intersecting at center T.

The diagram of circle is attached below.

In the diagram of circle, Angles R T S and Q T P are congruent.

So that,  [tex]\angle RTS=\angle QTP\\\\[/tex]

Since, both diameter are crossing each other.

So that, Angles R T S and Q T P are vertically opposite angles.

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find b

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

Answer:

Peter is 20 years old

Step-by-step explanation:

John= 2(Peter's age) (j=2p)

Peter= (Alice's age + 5) (P= A+5)

Okay, so let's substitute the equations now:

John= 2(Alice + 5)

So the equation for 5 years from now is:

2(A+5) + 5 = 3a (because he is 3 times as old as alice)

so, let's solve for that equation:

2a + 10 + 5 = 3a

subtract 2a from both sides:

15= a

so, Alice is going to be 15 years old, so now we can solve for Peter's age:

P= A + 5

P= 15 + 5

P = 20

Peter is 20 years old

Answer:

The initial value of the boat was $20,000

The percent decrease per year of the value of the boat is 10%.

The interval on which the value of the boat is decreasing while Harry has it is (0,10)

Step-by-step explanation:

It is given that the boat costs $20,000 in 2010 when x = 0. So, the initial value of the boat was $20,000.

Next, find the percent decrease per year of the value of the boat. Consider the general form of an exponential equation, y = a(b)x, where a is the initial value of the boat, b is the base of the exponent, x is the number of years after 2010, and y is the value of the boat, in dollars.

Consider the point (1 , 18,000) which lies on the graph of this situation. Substitute x = 1, y = 18,000, and a = 20,000 into the exponential equation and isolate b.

Recall that for exponential decay, b = 1 - r where r represents the decay rate. Substitute b = 0.9 into this equation and solve for r.

So, the decay rate is 0.1, and the percent decrease per year of the value of the boat is 10%.

Harry bought the boat in 2010, and plans on selling it after 10 years in 2020. Therefore, the interval on which the value of the boat is decreasing while Harry has it is [0, 10].
