Answer:
- We have to find the value of 10y - 4z
<h2>Solution :</h2>
Given Values
Substituting these values in 10y - 3z
we get,
= 10 × 8 - 3 × 8
= 80 - 24
= 56
<h3><u>Hen</u><u>ce</u></h3>
To find this answer, we will add the two numbers:
410+289=699
We make 410 positive because both sides hold space and are on opposite sides of zero so the answer is 699.
I am doing with Question Number 2
Let the two numbers be 'x' and 'y'.
According to the question, the product of two numbers is 14.

So, xy=14 (Equation 1)
Now, one of the numbers is 3 ½ times the other.
So, 
(Equation 2)
Substituting the value of 'x' from equation 2 in equation 1, we get



So, y= 2 and -2
So,
and 
x=7 and -7
Numbers are 2,7 and -2,-7.
Sum of numbers 2 and 7 = 9
Sum of numbers -2 and -7 = -9.
a=144
b=48
c=60
d=132
This is what I got using my(online) calculator
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=<u>O</u>pposite over <u>H</u>ypotenuse
Cos=<u>A</u>djacent over <u>H</u>ypotenuse
Tan=<u>O</u>pposite over <u>A</u>djacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be
and cos A (adjacent over hypotenuse) would be
.
I hope this helps!
