Answer:
Estimate = 600,000
Step-by-step explanation:
An estimate can be defined as a rough calculation of a numerical value, usually the upper limitation.
Given the following numerical values;
212,514
396,705
To add the two values together, we would first of all determine the estimate.
Estimate of 212,514 = 200,000
Estimate of 396,705 = 400,000
Adding the two values;
200,000 + 400,000 = 600,000.
Actual addition of the values would have given;
212,514 + 396,705 = 609,219.
Therefore, 600,000 is an estimated value of 609,219.
Answer:
B
Step-by-step explanation:
the other person is wrong
So, first set the two Y values equal to each other.
4x+9 = -1+8x
Add and subtract values to both sides making the x coordinates on one side:
4x = 10
Finally, divide.
x = 10/4 = 2.5
The statements can be used to describe the original functions f(x) and g(x) are; Option B
<h3>How to interpret function graphs?</h3>
Let the functions be
f(x) = ax + b
g(x) = cx + d
Their sum is;
j(x) = (a + c)x + b + d
Their product is;
k(x) = (ax + b)(cx + d)
From the graph, we see that;
f(x) = x + 6
g(x) = -2x² + 8
f'(x) = 1
g'(x) = -4x

Answer:
h = 1.4
c = 2.8
Step-by-step explanation:
For each problem, remember the special triangle side ratios then use a proportion. To solve, isolate the variable.
For the triangle with the variable h:
Since two of the angles are 45, this is an isosceles triangle. All isosceles triangles have two equal sides that are not the hypotenuse.
In a right isosceles triangle, the ratio for regular side to hypotenuse is 1 to √2.
h = √2
h ≈ 1.4
For the triangle with the variable c:
The is an equilateral triangle cut in half because the angles are 30 and 60.
The side ratio of altitude to hypotenuse is √3 to 2.
c = 2√2
c ≈ 2.8
