Step-by-step explanation:

Step 1: List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2: Find the values for the given numbers

sin(J) = opposite/hypotenuse = 24/25

tan(J) = opposite/adjacent = 24/7

sin(K) = opposite/hypotenuse = 7/25

tan(K) = opposite/adjacent = 7/24

Step 3: Check if the answers match

24/25 = 24/25 So it is TRUE

24/7 != 7/25 So it is FALSE

7/25 != 24/25 So it is FALSE

7/24 = 7/24 So it is TRUE

Answer: TRUE, FALSE, FALSE, TRUE

Solve −3x2 + 30x − 90 = 0

Ray Of Light [21]

Step-by-step explanation:

so, it is a quadratic equation :

-3x² + 30x - 90 = 0

the first thing we can do is divide by 3

-x² + 10x - 30 = 0

remember, the formula to solve and find the 2 solutions is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case here

a = -1

b = 10

c = -30

x = (-10 ± sqrt(100 - 4×-1×-30))/-2 =

= (-10 ± sqrt(100 - 120))/-2 = (-10 ± sqrt(-20))/-2 =

= (-10 ± sqrt(4×5)i)/-2 = (-10 ± 2×sqrt(5)i)/-2 =

= 5 ± -sqrt(5)i

x1 = 5 - sqrt(5)i

x2 = 5 + sqrt(5)i

remember, i = sqrt(-1), a complex number.

Help pls asap!!!!!!!!!!!!!!!!!!!!

yawa3891 [41]

Hello!

We can put the x values in and see if we get y

Option 1:
Set A: y = 4x - 2

Do the first values

y = 4(-1) - 2

y = -4 - 2

y = -6

Look at the next one to be sure

y = 4(1) - 2

y = 4 - 2

y = 2

So the set A equation is correct we can look at set be now

y = x + 4

y = -5 + 4

y = -1

Try the next one to be sure

y = -2 + 4

y = 2

So the set B equation is also correct

The answer is the first one

Hope this helps!

Determine the larger of two consecutive integers whose sum add to 85

Vesnalui [34]

N+(n+1) = 85. 2n+1=85, 2n=84. n=42. So the consecutive integers are 42 and 43, and the larger one is 43.

aniked [119]

Step-by-step explanation:

Write properties of function:

x intercept/zero: ; T1= -1 and T2=10

vertex form: g(t)= (t-9/2)^2, (-121/4)

vertex: 9/2, 121/4

Explanation Write properties of function: Write properties of function:

x intercept/zero: ; t1=-1, and t2=10

vertex form: (t-9/2)^2, (-121/4)

vertex: 9/2, 121/4
