3.3e+7
Step-by-step explanation:
Answer:
Yes, at positive x-coordinates.
Step-by-step explanation:
Finding the equation for g(x):
Slope = (3-6)/ (1-0) = -3
y-intercept = y value when x = 0 = 6.
So g(x) = -3x + 6
Solve them simultaneously:
x^2 + y^2 = 16
g(x) : y = -3x + 6
Substitute for y in the first equation:
x^2 + (-3x + 6)^2 = 16
x^2 + ( 9x^2 - 36x + 36) = 16
10x^2 - 36x + 20 = 0
5x^2 - 18x + 10 = 0
x = [-(-18) +/- sqrt ( (-18)^2 - 4 * -18 * 10)] / (5*2)
= ( 18 +/- sqrt 124 )/ 10
= (1.8) +/- 1,114
These 2 roots are both positive.
Answer:
The surface area is 162 yards
Step-by-step explanation:
A = 2(w l + h l + h w)
A = 2(7 (3) + 6 (3) + 6 (7))
7 x 3 = 21
6 x 3 = 18
6 x 7 = 42
21 + 18 +42 = 81
81 x 2 = 162
Step-by-step explanation:
to find the sum of nth term
equation is
n/2 ( 2a + (n-1)d) where a is the 1st term and d is the common difference
5/2 ( 120 +( 4 × 31))
5/2 ( 120 + 124)
5/2 × 244
5 × 122 <em>dividing</em><em> </em><em>2</em><em>4</em><em>4</em><em> </em><em>by</em><em> </em><em>2</em>
610
It gets 25$ off at first then 30$ off so the price would be 70$
