Describe the nature of the roots for the equation 49x^2-
28x +4 = 0
O one real root
one complex root
O two complex roots
O two real roots
Answer:
Step-by-step explanation:
One real root
The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
The equation is given as:
[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]
To determine the nature of the roots, we make use of determinants.
The determinant (d) of a quadratic equation is calculated
[tex]\mathbf{d = b^2 - 4ac}[/tex]
Where the quadratic equation is:
[tex]\mathbf{ax^2 + bx + c = 0}[/tex]
By comparison, we have:
[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]
So, we have:
[tex]\mathbf{d = b^2 - 4ac}[/tex]
[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]
[tex]\mathbf{d = 784 - 784}[/tex]
[tex]\mathbf{d = 0}[/tex]
When d = 0, then the function has one real root.
Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root

The discriminant of a quadratic equation is 34. Which of the following is true about its roots? *
a.The roots are imaginary and unequal.
b.The roots are real, rational, and unequal.
c.The roots are real, irrational and unequal.
d.The roots are real, rational and equal.
Answer:
d. The roots are real, rational and equal.Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers

Answer:
4/5 - 1/4
Step-by-step explanation:
4/5 =0.8

⇒0.8 - 0.25 = 0.55 (decimal form)
⇒4/5 - 1/4 = 11/20 (exact form-fraction)
At a cherry farm, the cost per pound of cherries depends on the amount of cherries bought. For an amount up to 100 pounds, the cost is $1.75 per pound, and, for an amount over 100 pounds, the cost is $1.50 per pound. Ralph bought 60 pounds and Jeff bought 80 pounds separately. If they had bought the total amount jointly, how much would they have saved?
Answer:
they would have saved 35 dollars
Step-by-step explanation:
Ralph on his own would have paid 105 and jeff 140 but together with the discount they could save $35 by paying 210 in total with the discount.

A painter mixes cans of green and white paint to make the shade needed for painting a bedroom. The table shows the
ratios he can use for the color he wants.
Green cans (g) 6 10 16 18
White cans (W) 915 24 27
Which is a direct variation equation for this relationship?
Answer:
A. 2/3w
Step-by-step explanation:
Option A is correct, g = 2/3 w is a direct variation equation for the given relationship
To determine the direct variation equation, we need to check if the ratio of green cans (g) to white cans (w) is constant across all the given ratios.
Let's calculate the ratios for each case:
For the first ratio: g = 6 and w = 9
g/w = 6/9
= 2/3
For the second ratio: g = 10 and w = 15
g/w = 10/15
= 2/3
For the third ratio: g = 16 and w = 24
g/w = 16/24
= 2/3
For the fourth ratio: g = 18 and w = 27
g/w = 18/27
= 2/3
Since the ratio of g/w is the same (2/3) for all cases, we can see that the relationship between green cans (g) and white cans (w) is a direct variation
Hence, the direct variation equation is g = 2/3 w, option A is correct.

If h and j are inverse functions, what is h(j(15))
Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.

George deposits $3,500 at 3.25% interest compounded monthly. What will his ending balance be after 5 years?
Answer:
FV= $4,117.1
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,500
Number of periods= 5*12= 60 months
Interest rate (i)= 0.0325/12= 0.00271
To calculate the Future Value, we need to use the following formula:
FV=PV*(1+i)^n
