Answer: 1.25 or 1 1/4 pts
Answer:
Step-by-step explanation:
From the figure attached,
Point B has been dilated to form point B'.
B(3, 1) → B'(6, 2)
→ B'[(2 × 3), (2 × 1)]
Since rule for the dilation of a point (x, y) by a factor of k is,
B(x, y) → B'(kx, ky)
By comparing the coordinates k = 2 is the scale factor by which the point B has been dilated about the origin.
Therefore, other vertices of the quadrilateral will be,
A(-2, 3) → A'(-4, 6)
C(1, -1) → C'(2, -2)
D(-3, -2) → D'(-6, -4)
1. 3cm ,M is the midpoint
2. ND , 3cm,
3. BC, According to the diagram
4. 12 Cm
In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
Answer:
7x^2 + 7
Step-by-step explanation:
So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.
Hope that explanation makes sense
