The estimate should be 60 (because you round down the 6.45 and 10.2 to 6 and 10). Since you rounded down, the actual product will be greater than the estimate.
Hence, the amount saved by buying at Supergrocery A is; $6.10 - $4.76 = $1.34
<h3>Slope of Graphs;</h3>
According to the questions;
The cost to buy 1 pound of beef from the Supergrocery A is the slope of the given graph;
- Slope, m = (47.60 - 23.80)/(10-5)
Therefore, the cost per pound of beef at Supergrocery A is $4.76 which is cheaper than $6.10 at Supergrocery B.
Hence, the amount saved by buying at Supergrocery A is; $6.10 - $4.76 = $1.34

The value of the given surface integral is 4.
The given plane intercepts the coordinate axes at (2, 0, 0), (0, 2, 0), and (4, 0, 0). These point are the coordinates of a triangular region that we can parameterize using.
<h3>What is the surface integral?</h3>
A surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. Given a surface, one may integrate a scalar field over the surface or a vector field.
with 0≤u≤1 and 0≤v≤1. Then the surface element ds is equivalent to
The surface integral is then
Therefore the value of the given surface integral is 4.

Answer:
B. 3x^2 - 2x - 1.
Step-by-step explanation:
(f + g)x = f(x) + g(x)
= -4x + 3 + 3x^2 + 2x - 4
Adding like terms we get the answer:
= 3x^2 - 2x - 1.
Answer:
See below. No image this time.
Step-by-step explanation:
1.
- P(2, 8) → P'(-5, 1), which it went 7 units to the left, and 7 units down. Here is the equation: (x - 7, y - 7).
2.
- R(-4, -9) → R'(-4, -2), which went 7 units up. Here is the equation: (x, y + 7).
3.
- M(10, -3) → M'(3, 4), which went 7 units left, 7 units up. Here's the equation: (x - 7, y + 7).
4.
- K(7, 11) → K'(0, 11), which went 7 units left. Here is the equation: (x - 7, y).
