Answer:

sin g° = x ÷ z

Step-by-step explanation:

Given a right angled triangle with the following dimension

Triangle ACB, angle C is a right angle, angle B measures g degrees, angle A measures h degrees, segment AC measures x, segment CB measures y, and segment AB measures z.

Find the diagram in the attachment.

Using the SOH, CAH, TOA identity

When considering angle g°, the opposite side of the triangle will be the side facing the angle g° i.e x

Hypotenuse is the longest side |AB| = z

according to SOH,

Sin g° = Opposite/Hypotenuse

Sin g° = |AC|/|AB|

Sin g° = x/z

Therefore sin g° = x ÷ z is correct

F(x)=x^2+3x-5. find and simplify f(x+h)-f(x)

jarptica [38.1K]

Answer:

$f(x + h) - f(x) = h^2 + 3h - 5$

Step-by-step explanation:

Given

$f(x) = x^2 + 3x - 5$

Required

Find f(x + h) - f(x)

In functions:

$f(x + h) = f(x) + f(h)$

So:

$f(x + h) - f(x) = f(x) + f(h) - f(x)$

Collect Like Terms

$f(x + h) - f(x) = f(x) - f(x)+ f(h)$

$f(x + h) - f(x) = f(h)$

Solving for f(h)

$f(h) = h^2 + 3h - 5$

So:

$f(x + h) - f(x) = h^2 + 3h - 5$

Solve the system using substitution. -2x+5y=19<br> 3x-4=y

omeli [17]

Answer:

answer is x=3 and y=5.... so it is (3,5)

Step-by-step explanation:

you want to combine them so y=3x-4 so subsitute y

-2x+5(3x-4)=19

-2x+15x-20=19

+20 +20

13x=39

--- ---

13 13

x=3

now subsitute 3 into x into any problem...

3(3)-4=y

9-4=y

and 9-4 is 5 so it is...

(3,5)

Four microprocessors are randomly selected from a lot of 100

ira [324]

Answer:

Step-by-step explanation:

From the set of 100 with 10 defective microprocessors, the probability of picking a defective one is;

10/100 = 1/10

From the set of 99 remaining and 9 defective microprocessors, the probability of picking a defective one is;

9/99 = 1/11

From the set of 98 remaining and 8 defective microprocessors, the probability of picking a defective one is;

8/98 = 4/49

From the set of 97 remaining and 7 defective microprocessors, the probability of picking a defective one is;

7/97

Adding all 4 probabilities together, we get;

1/10 + 1/11 + 4/49 + 7/97 = 0.345 or 34.5%
