Answer for 1st question:

The answer is A. 4/20

Step-by-step explanation:

The probability of landing on a vowel would be 2/5.

The probability of landing on an even number would be 2/4.

Now we just need to solve the probability of landing on a vowel and an even number.

2/5 x 2/4 = 4/20.

Thereore, the probability of landing on a vowel and an even number is 4/20.

Answer for 2nd question:

The answer is B. 1/20

Step-by-step explanation:

The probability of landing on a C would be 1/5.

The probability of landing on a 4 would be 1/4.

Again, we just need to solve the probability of landing on a C and a 4.

1/5 x 1/4 = 1/20.

Therefore, the probability of landing a C and a 4 is 1/20.

Can someone help me to solve this question sec(x)sin(x)-2sin(x)=0 [0,2pi) ? ASAP!!!!!
BigorU [14]

Answer:

x = 0, π/3, π, 5π/3

Step-by-step explanation:

sec(x)sin(x) - 2sin(x) = 0

factor out sin(x)

sin(x)[sec(x) - 2] = 0

then solve by splitting into two parts:

sin(x) = 0 and sec(x) - 2 = 0

x = 0, π    and x = π/3, 5π/3 then plug in to original equation to check

What is the vertex of y=-2x^2+10x+1 and is it a minimum or maximum
Reika [66]

Answer:

Step-by-step explanation:

it is maximum.

when leading coefficient of x² is negative,

It is downward parabola.

or

y=-2x²+10x+1

=-2(x²-5x+(-5/2)²-(-5/2)²)+1

=-2(x-5/2)²+2×25/4+1

=-2(x-5/2)²+25/2+1

=-2(x-5/2)²+27/2

maximum value of y is 27/2 and is attained at x=5/2

vertex is (5/2,27/2)
