Answer:
Hence, 0.0000087 can be expressed as 
.
Step-by-step explanation:
- Given 0.00000871
- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .
- Then count n and write no. as product with a power of 10 .
Step 1 of 1
Consider 0.00000871,
8.71
Decimal has moved 6 places to right.
The power will be negative as the original no. is less than 1 .
Answer:
A
Step-by-step explanation:
Given
x² - 16x + 64 = 0 ← left side is a perfect square and factors as
(x - 8)² = 0, thus
x - 8 = 0 ⇒ x = 8 with multiplicity 2
Thus x = 8 is the only solution → A
Step-by-step explanation:
u have to subtract 65 off of 25
Answer: The answer is 10 inches.
Step-by-step explanation: Given that the area of a trapezoid is 50 square inches and the bases are 3 inches and 7 inches. We are to find the height of the trapezoid.
We know that the area of a trapezoid with height 'h' and bases 'a' inches and 'b' inches is given by
In the given question,
a = 3 inches, b = 7 inches, A = 50 square inches, h = ?
Therefore,
Thus, the required height is 10 inches.
Given that the graph of the quadratic function.
We need to determine the vertex of the graph and also determine whether it is a minimum or maximum value.
<u>Vertex:</u>
The vertex of the parabola is the point at which the parabola makes a turn to form a U - shaped graph.
Hence, from the figure, the parabola turns at the point (0,-2) to form a U - shaped graph.
Therefore, the vertex of the graph is (0,-2)
<u>Minimum or maximum value:</u>
When the parabola is open upwards, then the vertex is the lowest point on the graph which is the minimum value on the graph.
Thus, the graph has a minimum value.
Hence, the vertex of the graph is (0,-2); minimum value.
Therefore, Option A is the correct answer.
