Answer:
The answer is A = 14 B = 4 14 - 4 = 10 I think.
Step-by-step explanation:
It's not a sum its a difference because this is a subtraction problem I think.
Answer:
a trapezoid
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
Answer:
It is 561 plus 562

common sense bro, add the miles and youll get the total traveld
Answer:
1845 years
Step-by-step explanation:
Decay of Carbon-14 is usually modeled by an exponential function. It x is the number of years since the original amount was brought into existence, then the fraction remaining (y) is modeled by ...
... y = (1/2)^(x/5730)
We want to find the value of x when y = 80% = 0.80. The equation is then ...
... 0.80 = 0.50^(x/5730)
Taking logarithms, we get
... log(0.80) = (x/5730)·log(0.50)
Multiplying by the inverse of the coefficient of x, we have
... x = 5730·log(0.80)/log(0.50) ≈ 1845 . . . . years
Answer:
First graph
Step-by-step explanation:
The y-intercept of f(x)=2(3)^x is found by letting x = 0: f(0) = 2(3)^0 = 2.
Thus, we can immediately eliminate the 2nd and 4th answer graphs.
Next, determine whether (1, 6) from the first graph satisfies f(x)=2(3)^x:
2(3)^1 = 2(3) = 6. Yes. So the first graph is the correct one.
