Answer:
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
We already know the slope so, so far the equation should look like this.
Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:
when you solve this equation you'll get b
So the equation is
Answer:
see explanation
Step-by-step explanation:
(a)
(the side required )² = sum of squares of other 2 sides - ( 2 × product of other 2 sides and cos(angle opposite side required ) )
x² = 12² + 15² - (2 × 12 × 15 × cos71°)
(b)
x² = 144 + 225 - 360cos71°
= 369 - 360cos71° ( take square root of both sides )
x =
≈ 16 cm ( to the nearest integer )
The answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be
4
Step-by-step explanation:
To simplify
.
Using exponential law the exponents of variables will be added when multiplied as per rule
we get
Now by dividing according to exponential rule the exponents of variables will be subtracted as per rule
So the answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be
