Answer:
Tn = 2n+4
T20 = 44
Step-by-step explanation:
Given Sn = n²+ 5 n-6
Tn = Sn - Sn-1
Sn-1 = (n-1)² + 5(n-1) - 6
Tn = n²+ 5n-6 - ((n-1)² + 5(n-1) - 6))
Tn = n²+ 5n-6-(n²-2n+1+5n-5-6)
Tn = n²+ 5n-6-n²+2n-1-5n+5+6
Tn = 2n-7+11
Tn = 2n+4
Get the general term is 2n+4
To get the 20th term;
T20 = 2(20) + 4
T20 = 40+4
T20 = 44
Hence the 20th term of the sequence is 44

Answer:
70
Step-by-step explanation:
Because PQ tangent to circle, angle P is 90
angle S = 180 - 90 - 20 = 70
According to the scale on a map, 1 inch on the map = 12 miles. How many miles are represented by 4 inches on the map?
Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
The miles are represented by 4 inches on the map, if the scale on a map, is 1 inch on the map = 12 miles is 48 miles.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given data:
According to the scale on a map, 1 inch on the map = 12 miles
Calculate the miles as shown below,
Miles in 4 inches on the map = 4 × miles in 1 inch on the map
Miles in 4 inches on the map = 4 × 12 = 48 miles,
Therefore, the miles are represented by 4 inches on the map, if the scale on a map, is 1 inch on the map = 12 miles is 48 miles.

please helpppp !!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:15
Step-by-step explanation: So we have this triangle but it's not a right triangle right so we can't just Pythagorean theorem our way out. So we have to treat the sizes as ratios. 2:12 is the ratio of the smaller triangle. 12 increases to 78 which means side 2 has to increase as well by the same ratio so 78/12 = 6.5 and 6.5*2=13 so PQ is 13 and to find NQ just add NP and PQ or 2+13 = 15

Answer:
∠ JHF = 69°
Step-by-step explanation:
Since HJ is a midline then it is parallel to EG , thus
∠ JHF and ∠ GEH are corresponding and congruent, then
7x + 62 = 79 - 10x ( add 10x to both sides )
17x + 62 = 79 ( subtract 62 from both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Thus
∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°
Answer:
7x + 62 = 180
7x= 180 - 62
x = 118 / 7
x = 16
7 × x = 7 × 16
112 + 62 = 174

Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x+4−3x=3x+2−3x
−2x+4=2
Step 2: Subtract 4 from both sides.
−2x+4−4=2−4
−2x=−2
Step 3: Divide both sides by -2.
-2x/-2 = -2/-2

HELP! Dont judge i really do need help!
Answer:
A.
Step-by-step explanation:
The coordinates are currently on the top left, which means one of the coordinates are negative. If you look at the chart, you can see that the X-axis is negative, and X is first on a coordinate plane. (X,Y) So, if the negative coordinate is X, and X goes first, then there's no other choice than to choose A, which is the only answer choice that has a negative X-axis in their coordinate plane! Hope this helps!
If cot theta is greater then 0 or sin theta is smaller than 0 then terminal arm of an angle lies in quadrants
Answer:
4th quadrant
Step-by-step explanation:
Given that:
cot θ > 0 or sin θ < 0
[tex]cot \theta = \dfrac{1}{tan \theta}[/tex]
where;
[tex]tan \theta = \dfrac{sin \theta}{cos \theta}[/tex]
∴
If [tex]cot \theta = \dfrac{cos \theta}{sin \theta}>0[/tex] or sin θ < 0, then the terminal arm of the angle lies in the 4th quadrant
