Answer:
The answer would be A (3x+2).
Answer:
The total distance Allie traveled was 0.81 miles.
Step-by-step explanation:
Since Allie rode her bike up a hill at an average speed of 12 feet / second, and she then rode back down the hill at an average speed of 60 feet / second, and the entire trip took her 2 minutes, to determine what is the total distance she traveled, the following calculation must be performed:
12 + 60 = 72
72 x 60 = 4320
1000 feet = 0.189394 miles
4320 feet = 0.8181818 miles
Therefore, the total distance Allie traveled was 0.81 miles.
Answer:
x=6
y=13
Step-by-step explanation:
The statement says that:
Been y the smaller and x the larger. The other equation that we have is the summation of the two numbers. Then we have 2 equations and 2 unknowns
Solving the equations the answers is x=13 and y=6.
All u do is divide 3 into 74 but 3 cant get into 74 so u do the number the close in that 3 times 24 in that 72 but if u do 25 times 3 that 75 in the number cant be greater so then u know it 24 times 3 then u subtract 74 from 72 in get 2 as the remainder so u have 2 as the hold number in 3 as the nemonator in 24 as the denatorator
The discriminant of the given quadratic equation as in the task content can be evaluated by means of the formula; D = b²-4ac and it's value is; 13.
<h3>What is the discriminant of the quadratic equation as given in the task content?</h3>
According to the task content, it follows that the quadratic equation whose discriminant is to be determined is; x²-5x+3=0.
By comparison with the standard form equation of a quadratic graph which goes thus; ax²+bx +c = 0, in which case, the determinant is given by the expression; b² - 4ac.
We can consequently evaluate the determinant of the quadratic equation in discuss as follows;
Determinant = b² -4ac = (-5)² - (4×1×3) = 25 - 12
Hence, the determinant in this case is; 13.
