If t = 5 and u = 19, what is vu + 25t?

The leading coefficient of the quadratic function a is negative

From the graph, we have the following points:

Vertex, (h,k) = (-4,3)

Point, (x,y) = (-3,2)

A quadratic equation is represented as:

y = a(x - h)^2 + k

So, we have:

2 = a(-3 + 4) + 3

Subtract 3 from both sides

-1 = a(-3 + 4)

Evaluate the difference

-1 = a

This gives

a = -1

Hence, the leading coefficient a is negative

Answer:

Step-by-step explanation:

Answer:  [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]

The sin(A) goes with 'a'

sin(B) goes with b

sin(C) goes with c

Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]

Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.

Answer:

1. 6.96500 kilogramos

2. 3.95 kilogramos

Answer:

1/6

Step-by-step explanation:

6^-2  / 6^-1

We know that a^b / a^c = a^(b-c)

6^(-2 - -1) = 6^(-2+1) = 6^-1

We know that a^-b = 1/a^b

1 /6^1 = 1/6

Answer:

1/6

Step-by-step explanation:

When dividing by exponents, you need to subtract the exponent from top to bottom. Ex: 5^3/5^2=5^1 which is just one, because you subtract 3 and two. In this case, 6^-2 / 6^-1 gets us 6^-1 which is the same thing as 1/6^1. Because remember, a^-x = 1/a^x.

Answer:

D

Step-by-step explanation:

You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Answer:

(3,5)

Step-by-step explanation:

For this equation, you need to solve it like simultaneous equations. Both of these have a 4y, so that is relatively easy to do, once you know how to.

The signs in front of the 4y are different, so you add the 2 equations (to remove the ys all together).

This should be (2x+-8x)+(-4y+4y)=(-14+-4), or (2x-8x)+(4y-4y)=(-14-4).

This can be expanded to -6x+0=-18, or -6x=-18.

Dividing both sides by -6 leaves you with x=3.

To find y, substitute this x value into either equation (I picked equation 1 as it is simpler). This gives you 2(3)-4y=-14, expanded to 6-4y=-14.

From there, you subtract the 6 from both sides, to get the y alone (giving -4y=-20).

By dividing both sides by -4, you get y=5.

This means the answer is (3,5).
