Answer: $f(x)=5x^2-4x+5$

Step-by-step explanation:

A quadratic function is as following; $ax^2+bx+c$

Notice that it cannot be $f(x)=0x^2-4x+7$ because if you solve; $0x^2=0$ which eliminates the $x^2$ .

What is the probability of spinning these two spinners and having each one land

asambeis [7]

Answer:

The probabilities are 0.4 and 0.6 respectively.

Step-by-step explanation:

We are given two spinning wheels with numbers on it and we have to find the probability of getting 3.

In the first wheel, there are 5 slots and the numbers are 3, 3, 2, 5 and 4.

So the probability of getting 3 = $\frac{number of 3's}{total number of slots}$

= $\frac{2}{5}$

= 0.4

In the second spinner there are three 3's and total of 5 slots.

So probability of getting 3 = $\frac{number of 3's}{total number of slots}$

= $\frac{3}{5}$

= 0.6

Hence the probabilities are 0.4 and 0.6 respectively.

Solve the remaining sides of the triangle: C=95(degrees), a=1/2, and b=1/3

snow_tiger [21]

There is only 1 remaining side

We have 2 sides and an included angle, we use the Law of Cosines to solve the third side:

c^2 = a^2 + b^2 -2ab *cos(C)

c^2 = .5^2 + .333333333...^2 - 2 * .5 * .3333333... * cos (95)

c^2 = .25 + .1111111111111111... -2*.5*.3333333333...* -0.087156

c^2 = 0.3611111111 + 0.029052

c^2 = 0.3901631111

c = 0.6246303796

34 points -2[3x-(b+2x)+(x-3b)] plz show steps i'm stuck

natali 33 [55]

First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
