Answer:
(-1, 7)
Step-by-step explanation:
We'll use the midpoint formula: ([x₁ + x₂]/2, [y₁ + y₂]/2)
x₁ = -4
x₂ = 2
y₁ = 6
y₂ = 8
Our equation will look like this
([-4 + 2]/2, [6 + 8]/2)
( -2/2, 14/2 )
(-1, 7)
1/2(z+18) is the answer i believe
Answer:
6a. r^5
6b. 18(4+√2)
Step-by-step explanation:
6a. The first term of the sequence is √r, and the common ratio is √r. Hence the 10th term will be ...
a1·r^(n-1) . . . for a1=√r and n=10.
√r·(√r)^(10-1) = (√r)^10 = r^5
_____
6b. The sum of n terms is given by ...
Sn = a1·(R^n -1)/(R -1)
For a1=√8 and the common ratio R = √8, the sum of 4 terms is ...
Or, you could add up the 4 terms:
Answer:
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
(2x+24)+(4x+43)+(x^2+1)=180
the awnser to this is x=8.
You plug in 8 into x
Angle 1: 2(8+24) --> 40
Angle 2: 4(8+43) -->75
Angle 3: (8^2+1) -->65
Check your work: add values together 40+75+65=180
Answer:
2.1275 is 2.12747677748 rounded to the nearest ten-thousandth.
Step-by-step explanation:
Since the hundred-thousandth place is 5 or above, we would round the ten-thousandths place up. THis makes the number 2.1275.
