Answer:

Step-by-step explanation:

We can see that we need to plug in 2 for x in the first equation

We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than or equal to 2)

so we have

3*(4*2+1)= 27

for g(x) we need to plug in x=1

we use the first piecewise equation because it's valid when x is less than 3

4(1²+2)=12

take their sum 27+12= 39

Answer:

39

Answer: tanA=3/4

Step-by-step explanation: If  cosA=4/5 then

sinA=√(1−cos2A)  {Because sin^2A+cos^2A=1}

=>sinA=√(1−16/25)

=>sinA=√(9/25)

=>sinA=3/5

Now as  tanA=sinA/cosA

=>tanA=3/5×5/4  {Because 1/cosA=5/4}

=>tanA=3/4

Answer:

3.49285 for part 1

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

In pattern A, we see that each number is 3 more than the one before it. B is incorrect because the pattern is +9. C is incorrect because the numbers in Pattern A is 3x Less than the corresponding numbers in Pattern B. D is incorrect because the numbers in Pattern B are 3x more than the numbers in Pattern A.

Hope this helps!

Answer:

Yes I agree with the person above because pattern A is adding by 3.

Answer: the median is 30 and the mean is 26.4

Step-by-step explanation: to find the median you order it from least to greater and find the middle number. For the mean add all numbers and divide from how many numbers are there , so you would divide by 5.

Answer:

P(candy chosen is red) = 58/200

Step-by-step explanation:

0.29 is the probability that a candy chosen at random will be red.

The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.

A machine contains = 76 green candies

B machine contains = 42 orange candies

C  machine contains = 58 red candies

D  machine contains = 24 yellow candies

Probability = 58 / 76 + 42+ 58+ 24

                  = 58 / 200

                  = 0.29

0.29 is the probability that a candy chosen at random will be red.

Answer:

12

Step-by-step explanation:

Answer:

The answer is A.

Step-by-step explanation:

The angle your looking at is a 90 degree angle therefore if you split it in half that makes each side 45 degrees. Just off of the fact that B says, "The measure of the smaller angle is 55 degrees" already makes it completely wrong since it would be have to be smaller than 45 degrees.

Answer:

W(0,-4)

Step-by-step explanation:

By translating right, we add the translation unit to the given coordinate of the x-axis

By translating downwards, we have to subtract the translation unit from the given coordinate of the y-axis

So from what we have here;

We are going to add 5 to the x-axis value and subtract 9 from the y-axis value

Thus, we have it that;

W’ (-5 + 5, 5 -9)

W’ (0,-4)

Answer:

[tex]y = 2x - 5[/tex]

Substitute the value of y as 2x - 5 in the equation.

[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Now, find the value of y

[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]

⎇ x = x = x, equals 10

⎇ y = y = y, equals 15

Answer:

if y = 2x-5

then in the second equation we can find the value of x

5x-4(2x-5) = -10

5x-8x+20 = -10

-3x = -30

x = 10

then the value of y = 20-5 = 15

therefore the value of x = 10 and y =15 (ans)
