Step-by-step explanation:
Exponential function is given by general form 
Where a and b are constants.
say a=1 and b=2 then we can write function as :
or 
To graph this or any exponential function, we just need to find some points then join them by a curved line.
Like plug x=0, 1, 2,... into above function and find points:
plug x=1
Hence point is (1,2)
Find more points similarly then graph them to get the graph as shown below:
Answer:
b
Step-by-step explanation:
Answer:
CD = 4
Step-by-step explanation:
GH bisects CF <u><em>means</em></u> CF = 2 CD
CF = 2 CD
⇔ 2y - 2 = 2×(3y - 11)
⇔ 2y - 2 = 6y - 22
⇔ 22 - 2 = 6y - 2y
⇔ 20 = 4y
⇔ y = 5
<u>Calculating CD ,For y = 5</u> :
CD = 3y - 11
= 3(5) - 11
= 15 - 11
= 4
It's the parallelogram. Therefore
ML = JK, JM = KL, m∠L = m∠J, m∠M = m∠K and m∠M + m∠L = 180°.
ML = 21 → JK = 21
JM = 29 → KL = 29
m∠L = 127° → m∠J = 127°
m∠M + m∠L = 180° → m∠M + 127° = 180° → m∠M = 53°
m∠M = 53° → m∠K = 53°
Answer:
5 cm
Step-by-step explanation:
13² - 12² = x²
169 - 144 = x²
25 = x²
5 = x
