Answer:
70
Step-by-step explanation:
We have the final part 4x/40 = 7. We can simplify this to x/10 = 7 by dividing the numerator and the denominator by 4. We then multiply both sides by 10 to get x = 70
Answer: The equation is y = 3.25 + 7.5x and Todd bought 11 pictures
Step-by-step explanation:
The number from standard form to decimal form is as follows:
2.077 × 10⁻⁴ = 0.0002077
<h3>How to express number in standard form?</h3>
Standard form is a convenient way of writing very large or very small numbers.
Standard form is a way of writing a number so it is easier to read.
Standard form is like scientific notation and is typically used in science.
Standard form is like scientific notation and it is represented in the format as follows:
a × 10ᵇ
Therefore, the number is already in standard form but we can convert it back to decimal form as follows:
2.077 × 10⁻⁴ = 2.077 × 1 / 10000 = 0.0002077

#SPJ1
Here we're applying a basic physics rule for vertical motion where the only pull on the object is gravity.
This rule has the form
h(t) = h + v t + (1/2)a*t^2
o o
To adapt this rule to this particular question replace h with 0, as the
o
upward path of the object begins at 0 ft. Replace v with +15 ft/sec.
o
Replace "a" with (-32.2 ft/(sec^2); this is the acceleration due to gravity.
Then we have the following, with the label F(t):
F(t) = 0 + (15 ft/sec)t + (1/2)(-32.2 ft)/(sec^2), or
F(t) = 15t - 16.1t^2. Thus, Choice D is correct.
Please note: To avoid confusion, please use " ^ " to denote exponentiation:
F(t) = -16t^2 + 15t
Answer:
B
Step-by-step explanation:
lets start off by looking at point A (1,1)
4 units to the right is along the x-axis, so the x-coordinate would be 5 (1 + 4)
2 units up is on the y-axis, so the y-coordinate would be 3 (1 + 2)
A is now (5,3). we can eliminate choices A, C, and D as they each have negative numbers in them, and we are moving in the positive direction, not the negative.
the answer is B
