Step-by-step explanation:
isn't like any of the other terms because it is being raised to the second power, so you can leave it alone.
-2t + 5t are like terms because they are both coefficients with the variable t. You can combine these to get 3t.
The only term left is -4, so that will remain the same.
Now, you can combine all of these terms to get
+ 3t - 4.
2x+3y=9
X=(y+2)
2(y+2)+3y=9
2y+4+3y=9
-4 -4
2y+3y=5
5y=5
Y= 1
Hi!
This is a fun one, as it delves into basic trigonometry.
We're going to use the Pythagorean theorem here, which says that for right triangles where "c" is the hypotenuse,
a² + b² = c²
We have to split this large triangle into two parts, both of which are right triangles. (This is why they drew a line in the middle to tell you that the larger triangle is composed of two right triangles.)
Let's do the one on the right first.
We know that the length of the hypotenuse is 10, and that the length of one of the legs is 6.5. If we plug this into our equation, we'll get the length of the other leg. I'm choosing "b" to be 6.5, but it really doesn't matter if you pick "a" or "b", so long as you reserve "c" for the hypotenuse (longest side).
a² + 6.5² = 10²
a² + 42.25 = 100
a² = 57.75
√a² = √57.75
a ≈ 7.6
Therefore, the length of DC is about 7.6.
Find the length of AD using the same method (7.5 is the hypotenuse "c", and 6.5 is one of the legs "a" or "b"). Then, once you have AD, add the lengths of AD and DC to get AC.
Have a great one!
Answer:
Step-by-step explanation:
distance =
Let:
(x₁ , y₁) = (0 , 5)
(x₂ , y₂) = (8 , 0)
Plug in the corresponding numbers to the corresponding variables:
Remember to follow PEMDAS. Solve the parenthesis first:
distance =
distance =
Solve for the powers next:
distance =
distance =
Simplify:
distance =
distance =
