Answer:
It helps you see the equation in "picture" form.
Step-by-step explanation:
When you see the inequality in a graph form, most people can benefit from seeing a different version of the same problem.
Answer:
18 kilometres
Step-by-step explanation:
Speed of the car is 72 kilometres per hour
means the car runs 72 kilometers within 60 minutes
so, the car will travel in 15 mins,
72×15/60
= 72/4 = 18 kilometres
Answer:
−x^2−11
Step-by-step explanation:
Distribute the Negative Sign:
=−3x−4+−1(x^2−3x+7)
=−3x+−4+−1x^2+−1(−3x)+(−1)(7)
=−3x+−4+−x^2+3x+−7
Combine Like Terms:
=−3x+−4+−x^2+3x+−7
=(−x^2)+(−3x+3x)+(−4+−7)
=−x^2+−11
We know that
applying the law of sines
50/sin 40=60/sin x
50*sin x=60*sin 40
sin x=[60*sin 40]/50
sin x=0.7713
x=arc sin (0.7713)----> x=50.47°--------> x=50.5°
the answer is
x=50.5 °
