Answer:
Jersey cost $8 and pair of shorts $5
Step-by-step explanation:
There are several ways to solve this, but I will find the solution using the system of equations.
Let's mark price of jersey with x, and price of pair of shorts with y. That means:
12x + 12y = 156
4x + 6y = 62
Now, we can multiply the second equation with -2 to cancel out y:
12x + 12y = 156
-8x - 12y = -124
That only leaves us with:
12x - 8x = 156 - 124
4x = 32
x = $8
Now we plug the value for x into any equation to find y:
4x + 6y = 62
32 + 6y = 62
6y = 30
y = $5
89, 91, 93.

Answer:
- g(2.95) ≈ -1.8; g(3.05) ≈ -0.2
- A) tangents are increasing in slope, so the tangent is below the curve, and estimates are too small.
Step-by-step explanation:
(a) The linear approximation of g(x) at x=b will be ...
g(x) ≈ g'(b)(x -b) +g(b)
Using the given relations, this is ...
g'(3) = 3² +7 = 16
g(x) ≈ 16(x -3) -1
Then the points of interest are ...
g(2.95) ≈ 16(2.95 -3) -1 = -1.8
g(3.05) ≈ 16(3.05 -3) -1 = -0.2
__
(b) At x=3, the slope of the curve is increasing, so the tangent lies below the curve. The estimates are too small. (Matches description A.)
Answer:
58.5 mg
Step-by-step explanation:
Drink: 130% of RDA of vitamin X
RDA vitamin X = 45mg
130% of 45 = mg in the drink
130% = 130/100 = 1.3
130% of 45 = 1.3*45 = 58.5
So, this new drink has 58.5 mg of vitamin
Answer:
One triangle
Step-by-step explanation:
-The triangle's dimensions are defined and fixed.
-Given the fixed dimensions, only one unique triangle can be constructed.
-Hence, only one triangle of the dimensions 7.2cm, 6.9cm and 12.8 cm can be formed.
