5a + 4 1\3
You put work with the number with variable then the number without the variable do not forget about the positive and negative.
Answer:
- 340
Step-by-step explanation:
The sum to n terms of an AP is
= ( a + l ) → a is the first term and l the last term
Here a = - 76 and = - 9360 , thus
( - 76 + l ) = - 9360
22.5(- 76 + l) = - 9360 ( divide both sides by 22.5 )
- 76 + l = - 416 ( add 76 to both sides )
l = - 340 ← the last term in the sequence
Answer:
y = 4
Step-by-step explanation:
5/2y = 10
5/2y x 2/5 = 10 x 2/5
Multiply each side by the reciprocal
y = 4
a) The domain of a function refers to the set of values of x that satisfy the function. On the graph, it is between the minimum value of x on the left and the maximum value of x on the right. Since the line continues to the left and right, it tends towards infinity on both sides. Hence,
Domain = (- infinity, infinity)
b) The range of a function refers to the set of values of y that satisfy the function. On the graph, it is between the minimum value of at the bottom and the maximum value of y at the top. The maximimum value of y is - 1 and the minimum is negative infinity. Hence,
Range = (- infinity, - 1}
c) The x intercept is the value of x when y is zero. It occurs at the point where the line cuts the x axis. Since the line doesn't cut the x axis, there is no x intercept.
d) The y intercept is the value of y when x is zero. It occurs at the point where the line cuts the y axis. It cuts the y axis at x = - 4
Thus, y intercept = - 4
e) the function value, f(- 4) is the value of y at x = - 4. From the graph,
f(- 4) = - 2
the function value, f(0) is the value of y at x = 0. From the graph,
f(0) = - 4
Answer:
The distance as product of 38 and a power of 10 is
Step-by-step explanation:
In math when we're dealing with big numbers like this we express them in power of 10, since it'll be easyer to read that way. We take the parts of the number to the left that are not equal to "0", in this case 38, and multiply it by a power of 10. The expoent to this power of 10 will be the number of "0" after the 38 and before the ",". In this case the closest distance from Earth to Venus is 38,000,000 (there's a typo in the question). So we take the 38 and multiply it by , since there are 6 zeros.
The distance as product of 38 and a power of 10 is
