If 0 ≤ Ø < 90 degrees, and tan Ø= 2/3, what is sinØ + cosØ?

Alika [10]

Answer:

1.38

Step-by-step explanation:

tan Ø = 2/3

Ø = tan⁻¹(2/3)

Ø = 33.69

sin 33.69 ≈ 0.55

cos 33.69 ≈ 0.83

sin Ø + cos Ø ≈ 1.38

Can someone help me solve A and B? I'm confused:(

IceJOKER [234]

P(a or b)= p(a)+p(b)-p(a and b)
0.7=0.6+p(b)-0.3
p(b)=0.4

p(a or b)= p(a)+p(b)-p(a and b)
=0.6+0.4-0.3
=0.7

If 10% of all machines become worthless every year (they depreciate, in other words), then how many machines will become worthle

nikklg [1K]

Answer: Country A - 10machines

Country A - 1,000machines

Country A - 10,000machine

step-by-step explanation:

Since 10℅ of all machines becomes worthless every year, let's look at each country.

If 100 machines are all the machines in country A, then 10% of all the machines in country A (i.e 100 machines) will be 10% of 100 = 10 machines.

Similarly for country B, it will be equivalent to 10% of 10000, which is equal to 1,000machines.

Same goes for country C i.e 10% of 1000000 = 10,000machines are worthless.

Simplify and state the domain for x^2-x-12/x-4

saw5 [17]

The domain of a function is the set of input values the function can take

The domain is all set of real numbers

<h3>How to determine the domain</h3>

The expression is given as:

$\frac{x^2 - x - 12}{x - 4}$

Factorize the numerator of the expression

$\frac{(x - 4)(x + 3)}{x - 4}$

Simplify: Cancel out the common terms

$x + 3$

The above expression can take any value of x.

Hence, the domain is all set of real numbers
