Answer:
1)24 2)36 3)240
Step-by-step explanation:
1) area of triangle = 1/2b*h so 7*4=28 28/2=14
therefore area =24
2)9*4=36
3)15*16=240
I tried my best with 1, 2, and 3
Answer:
- It is a linear equation
- The graph of the equation will show that the <em>y</em> values increase as the <em>x</em> values increase.
Step-by-step explanation:
The pay Michael gets (y) is the amount per paper ($0.40) multiplied by the number of papers (x) and that product added to the daily base pay of $5. Michael's daily pay (in dollars) can be described by ...
y = 5.00 + 0.40x
This is a linear equation with a positive slope (meaning y goes up when x goes up).
answer

explanation
since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola
since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)
our equation so far is
(x - 4)(x + 2)
= 
= 
since the function is reflected across the x-axis, multiply the equation by -1

= 
since the function has a vertical stretch of 3, multiply the equation by 3

= 
One thing to bear in mind with trigonometric expressions is that, the exponent location is next to the function name, instead of the whole expression, though it applies to the whole thing, namely cos²(x), is really [ cos(x) ]², and that matters for using the chain rule.
