Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:
Where the point (h, k) is the center of the ellipse
In this case we have the equation
Note that its shape matches that of a ellipse with center (9, -2)
Therefore the answer is the obtion C
Answer:
t = 8588 years
Step-by-step explanation:
From the given information:
Using the formula:
Given that:
= 5730 years
Then:
k = 1.20968 × 10⁻⁴
However; the expression to find the value of x is:
(-1.20968 × 10⁻⁴ × t) = In(0.353846)
(-1.20968 × 10⁻⁴ × t) = -1.03889
t = 8588 years
Answer:
When we have a discount of X% of the original price, the new price is calculated as:
New price = (original price) - (original price)*(X%/100%)
In our case, let's define:
P = original price of the fishing pole
f = price of the fishing pole after the discount
X% = 20%
Then the equation for the price of the fishing pole is:
f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8
f = 0.8*P
This means that the price after the discount is 0.8 times the original price.
Answer:
x <7
Step-by-step explanation:
3x – 4 < 17
Add 4 to each side
3x – 4+4 < 17+4
3x < 21
Divide each side by 3
3x/3 < 21/3
x <7
Answer:
Step-by-step explanation:
its a dotted line so the inequality is either > or <
line pass thro' (2,-2), (0,0) and (-2,2)
so its eqn is y = -1x + 0
the shade area is under the dotted line
so the ans is
y < -1x + 0
