Answer:

$BC=4.42$

Step-by-step explanation:

Given:

∠B=70°

AB=13

cos(B°)= $\frac{Base}{Hypotenuse}$

cos(70°)= $\frac{BC}{13}$

Given: cos(70°)≈0.34

$0.34=\frac{BC}{13} \\\\BC=0.34*13\\\\BC=4.42$

The measurement of BC is

$BC=4.42$

Answer:

180 - 90 - 70 = 20

13/sin90 = BC / sin20

BC = 4.45

Which of the following is true about the function y=4*3^x

Trava [24]

Answer:

option-c

Step-by-step explanation:

we are given

$y=4(3)^x$

we will verify each options

option-A:

we can see that exponent is over 3

and it is positive and greater than 1

so, this function is increasing

so, this is FALSE

option-C:

At x=1:

$y=4(3)^1$

$y=12$

At x=2:

$y=4(3)^2$

$y=36$

$\frac{y_2}{y_1} =\frac{36}{12}$

$\frac{y_2}{y_1} =3$

$y_2=3y_1$

So, it is getting tripled

so, this is TRUE

option-b:

we can plug x=0

$y=4(3)^0$

$y=4$

so, this is FALSE

option-d:

we can plug x=1

$y=4(3)^1$

$y=12$

so, this is FALSE

The LCM of two numbers is 36 their GCD is 3 one of the number is 9 find the other number

Aleks04 [339]

Answer:

Step-by-step explanation:

The LCM of 9 and x = 36

The GCD is 3, that means the number has to be divisible by 3 as well.

We can look at all the factors of 36, and see which numbers fit the description

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

1: Does not have a GCD of 3

2: Does not have a GCD of 3

3: Has a GCD of 9, but LCM is 3, not 36

4: Does not have a GCD of 3

6: Has a GCD of 3, but LCM is 18, not 36

9: Number is given

12: Has GCD of 3, and LCM is 36

18: Has GCD of 9

36: Has GCD of 9

The only number that works is 12, with a GCD of 3, and an LCM of 36
