Answer:
i believe the answer is 117$
Step-by-step explanation:7*15=105 8*1.50=12... 12+105=117
I'll assume that's an exponent at the end there:
The first derivative gives the velocity. The second derivative gives the acceleration; increasing velocity is the same as positive acceleration. So we want to find when the second derivative is positive.
Let's see if we can use 
to avoid multiplying this out.
That worked; let's do it again:
That's a nice parabola. It's zero or negative for 
so positive everywhere else:
Answer: Increasing velocity when t < 1 or t > 3
When a figure is dilated, this means the corresponding sides of the shape is enlarged in a uniform multiple. In thsi case, the ratio of the sides remains the same. Thus, when ratio of the sides remains the same, the corresponding angles are also congruent in the dilated figure.
Michelle opened her bank account on September 1st with $25 and continues to deposit $25 each month. Calculate the time Michelle will have a total of $500 in her account.
Answer:
19 months
Step-by-step explanation:
Initial deposit =$25
Monthly deposit = $25
Total deposit, y after x months can be modeled using the relation :
y = $25 + $25x
To have a total of $500 ; y = 500
$500 = $25 + 25x
$500 - $25 = $25x
$475 = $25x
x = $475 / $25
x = 19 months
Hence, Michelle will have deposited a total of $500 in his account after 19 months
Answer:
4 3/8
Step-by-step explanation:
1. We can use the formula
<em>Area = L (length) x W (width)</em>
2. The area is unknown so we can substitute it for<em> a</em>
<em> </em>The length and width are both known, so we can plug them in.
<em>a= 2 1/2 x 1 3/4</em>
3. Solve by multiplying
<em>a=4 3/8</em>
