Hello,
When you dilate a shape by a scale factor of 2, you simply multiply the coordinates by 2.
Therefore, the points become:
A(2, 3) ===> A'(4, 6)
B(3, 5) ===> B'(6, 10)
C(7,4) ===> C'(14,8)
Good luck,
MrEQ
Hi there! There are 5,280 feet in one mile, and there are 30.48 cm per foot. To find the amount of centimeters in one mile, all you have to do is multiply 30.48 by 5,280. 30.48 * 5,280 is 160,934.4. There. There are 160,934.4 centimeters in one mile.
Answer:
C. b²< 40
Step-by-step explanation:
2x²+ bx + 5=0 has no real solutions
=> D< 0
b² < 4ac
b²< 4(2)(5)
b²< 40
Answer:
3, 7, 11, 15, 19, 23, 27,.......
Step-by-step explanation:
Let the first term and the common difference of the AP be a and d respectively.
Therefore,
a + (7- 1) d = 27
a + 6d = 27
a = 27 - 6d...... (1)
Therefore,
a + (12 - 1) d = 47
a + 11d = 47......(2)
From equations (1) & (2)
27 - 6d + 11d = 47
24 + 5d = 47
5d = 47 - 27
5d = 20
d = 20/5
d = 4
Plug d = 4 in equation (1) we find:
a = 27 - 6*4
a = 27 - 24
a = 3
Therefore,
Thus, the sequence is: 3, 7, 11, 15, 19, 23, 27,.......
Answer:
All real numbers
Step-by-step explanation:
Linear functions have a domain and range of all real numbers because they reach from -∞ to ∞ on the x-axis and y-axis.
An example is given below. The domain and range of the function are all real numbers.
