Answer:
W = -9/8
Step-by-step explanation:
for two perpendicular lines
W*V = -1
W = 9/8*(-1)
W= -9/8
If we want to simplify Algebraic Fractions:
We have to take a look at the numerator and the denominator
Why? Because to simplify we need to have a common multiple.
When we find the common multiple, we now know by which factor we have to break down the fraction in the numerator and the denominator
I have some examples attached below for help.
Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm
A = hw
Replace h with 4h
Replace w with 4w
A = (4w)(4h)
= 16hw
The area becomes 16 times larger.
Have an awesome day! :)
