Answer:

Step-by-step explanation:

y interept is +7

the slope in fraction form is y=-5/4+7

the slope is negative even though it looks like it is not going up or down

if that it is wrong then it is an undefined slope

other points you can plot- (1, 5.75) and (2, 5.75)

i am sorry i don't know the answer it would be great if you provide more information

Step-by-step explanation:

The length of the side is 1/√2 or √2/2 units after applying the sin ratio.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Using sin ratio to find the value of x:

sin45 = X/1

1/√2 = X/1

X = (1/√2)(√2/√2)

X = √2/2

Thus, the length of the side is 1/√2 or √2/2 units after applying the sin ratio.

Answer:

4(-2)-(0)-2(-1)

a negative number multiplied by a negative number will always equal a positive number as the two negatives cancel each other out.

-2 multiplied by -1 equals positive 2

this is why the 2 is positive.

Answer:

Step-by-step explanation:

On a position-time graph, "does not move" means the position is a constant—a horizontal line.

"Positive velocity" means the position is increasing as time increases. The graph goes up to the right. The rate of change (slope) is the velocity.

"Negative velocity" means the position is decreasing as time increases. The graph goes down to the right. Again, the rate of change (slope) is the velocity.

The various sections of the graph are identified in the attachment.

Answer:72

Step-by-step explanation:

72 and the angle to the top right of x are corresponding angles. This means they are the same. Using this, we can see that the same angle to the top right of x that we now know is 72 is also vertical to x. Vertical angles are also equal, so x = 72

The value of x is 72°

Parallel lines are lines in the same plane and of the the same distance.

The parallel line j and k are intersected by the transversals l and m.

Therefore, corresponding angles, alternate angles etc. can be formed.

Since the pair of parallel lines are cut by the transversal lines then the alternate exterior angles are congruent . Therefore,

x = ∠72°

∠x ≅ ∠72°(alternate exterior angles)

Answer:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Step-by-step explanation:

Given the expression

[tex]-6\:-\:7\:\left(c+10\right)[/tex]

simplifying the expression

[tex]-6-7\left(c+10\right)[/tex]

Expanding -7(c + 10) = -7c - 70

[tex]-6\:-\:7\:\left(c+10\right)=-6-7c-70[/tex]

subtract the numbers: -6 - 70 = -76

                           [tex]=-7c-76[/tex]

Therefore, we conclude that:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Answer:

y = 5x + 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 5x + y = 2 ( add 5x to both sides )

y = 5x + 2 ← in slope- intercept form

with slope m = 5

Parallel lines have equal slopes, then

y = 5x + c ← is the partial equation

To find c substitute (- 2, 1) into the partial equation

1 = - 10 + c ⇒ c = 1 + 10 = 11

y = 5x + 11 ← equation of parallel line

Answer:

Step-by-step explanation:

Answer:

When we have a function g(x)

We will have a maximum at x when:

g'(x) = 0

g''(x) < 0.

Now we start with:

g(x) = 3*x^4 - 8*x^3

The first derivation is:

g'(x) = 4*3*x^3 - 3*8*x^2

g'(x) = 12*x^3 - 24*x^2

We can rewrite this as:

g'(x) = x^2*(12*x - 24)

Now we want to solve:

g'(x) = 0 =  x^2*(12*x - 24)

We have one trivial solution, that is when x = 0.

The other solution will be when the term inside of the parentheses is equal to zero.

Then we need to solve:

12*x - 24 = 0

12*x = 24

x = 24/12 = 2

Then g'(x) is equal to zero for x = 0, and x = 2.

Notice that both of these points are included in the interval [ -2,2 ]

Now we need to look at the second derivative of g(x):

g''(x) = 3*12*x^2 - 2*24*x

g''(x) = 36*x^2 - 48*x

Ok, now we need to evaluate this in the two roots we found before:

if x = 0:

g''(0) = 36*0^2 - 48*0 = 0

g''(0) = 0

Then we do not have a maximum at x = 0, this is a point of inflection.

if x = 2:

g''(2) = 36*(2^2) - 48*2 = 48

then:

g''(2) > 0

This is an absolute minimum.

Now let's look only at the interval [ -2,2 ]

We know that:

g''(0) =  0

g''(2) > 0

Then at some point, we should have g''(x) < 0 in our interval.

We need to find the first point such that happens, so let's try with the lower limit of the interval but with the first derivation, if g'(x) < 0, this means that the function is decreasing from that point on, then that point will be a maximum in our interval.

x = -2

g'(-2) = (-2)^2*(12*-2 - 24) = -192

And if we look at the function:

g'(x) = x^2*(12*x - 24)

We can easily see that it is negative unitl x = 0, and then it keeps being negative until x = 2.

So in the interval  [ -2,2 ], the function g'(x) is always negative or zero, this means that in the interval  [ -2,2 ], the function g(x) is always decreasing or constant.

Then the absolute maximum of g(x) in the interval  [ -2,2 ]  will be  x = -2

this means that:

g(-2) ≥ g(x) for all x ∈  [ -2,2 ]

Answer:

she ran 10 miles a hour

Step-by-step explanation:

she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10

Heather's rate of speed last week was 1/12 miles/min.

Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.

Heather's rate of speed last week -

{r} = 4/48 = 1/12 miles/min

{r} = 1/12 miles/min

Therefore, Heather's rate of speed last week was 1/12 miles/min.

Answer:

2.) $520

3.) less

Step-by-step explanation:

I'm going to assume that the interst is compoudning and is convertable once a year

The compound interest formula for interest compounding only once a year is as follows

[tex]AV=PV(1+i)^n[/tex]

plug in the numbers and get

[tex]500(1+.04)^{1}=500*1.04=520[/tex]

3.) If the interest rate is lower at the credit union he would obvioulsy be paying less (assuming that this interest rate is convertable annually as well)
