Answer:
16 months
Step-by-step explanation:
40k-16.5k=23.5k. 23.5k/1450= A little bit more than 16 months.
Find the value of k , if one of the two roots of the equation : x2 + k X – 98 = 0 is double
the additive inverse of the other.
«+
C
Given:
[tex]x^2+kx-98=0[/tex]
One of the two roots of the given equation is double the additive inverse of the other.
To find:
The value of k.
Solution:
Let two roots of the given equation are [tex]\alpha[/tex] and [tex]\beta[/tex].
According to the question,
[tex]\beta=2(-\alpha)[/tex] (Additive inverse of [tex]\alpha[/tex] is [tex]-\alpha[/tex])
[tex]\beta=-2\alpha[/tex]
If [tex]\alpha[/tex] and [tex]\beta[/tex] are roots of the quadratic equation [tex]ax^2+bx+c=0,[/tex] then
[tex]\alpha+\beta=-\dfrac{b}{a}[/tex]
[tex]\alpha\beta=\dfrac{c}{a}[/tex]
We have,
[tex]x^2+kx-98=0[/tex]
Here, a =1, b=k and c=-98.
[tex]\alpha+\beta=-\dfrac{k}{1}[/tex]
[tex]\alpha-2\alpha=-k[/tex] [tex][\because \beta=-2\alpha][/tex]
[tex]-\alpha=-k[/tex]
[tex]\alpha=k[/tex] ...(i)
Now,
[tex]\alpha\beta=\dfrac{c}{a}[/tex]
[tex]\alpha(-2\alpha)=\dfrac{-98}{1}[/tex] [tex][\because \beta=-2\alpha][/tex]
[tex]-2\alpha^2=-98[/tex]
Divide both sides by -2.
[tex]\alpha^2=49[/tex]
Taking square root on both sides.
[tex]\alpha=\pm \sqrt{49}[/tex]
[tex]\alpha=\pm 7[/tex]
Using (i), we get
[tex]k=\pm 7[/tex]
Therefore, the value of k is either -1 or 1.

11x -20y=28 3x+4y =36
Answer:
x = 8
y = 3
Step-by-step explanation:
11x - 20y = 28
3x + 4y = 36
11x - 20y = 28
11x = 20y + 28
x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]
3x + 4y = 36
3 ( [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex] ) + 4y = 36
[tex]\frac{104}{11}[/tex]y = [tex]\frac{312}{11}[/tex]
y = 3
x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]
x = [tex]\frac{20}{11}[/tex] ( 3 ) + [tex]\frac{28}{11}[/tex]
x = 8

Two triangles, ABC and DEF, similar. <ABC = 101° and <BCA = 39°. Find the angle of FDE!
40°
EXPLANATIONKnown :Triangle ABC and DEF is similar<ABC = 101° = <DEF<BCA = 39° = <DFEAsked :Angle of FDEAnswer :
The sum of all triangle angle is 180°
101 + 39 = 140°

What is the slope of the line?
Answer:
One
Step-by-step explanation:
When you count the units from one point to another, the answer is one. The units are one to the right then one up. 1/1
Step-by-step explanation:
slope =1
since the intercepted part of X_ axis and y_ axis are equal
so , the line make 45 angle with x_ axis
slope = tan O =1

Step-by-step explanation:
Asymptotes 3
g(x) = [tex]\frac{3x}{x^2-3x-10}[/tex]
Factors of denominator will be,
x² - 3x - 10 = x² - 5x + 2x - 10
= x(x - 5) + 2(x - 5)
= (x + 2)(x - 5)
Therefore, factored form of g(x) will be,
g(x) = [tex]\frac{3x}{(x + 2)(x - 5)}[/tex]
Asymptotes 4
h(x) = [tex]\frac{(x-5)}{x^{2} + 14x + 40}[/tex]
= [tex]\frac{x-5}{x^{2}+10x+4x+40}[/tex]
= [tex]\frac{x-5}{x(x+10)+4(x+10)}[/tex]
= [tex]\frac{x-5}{(x+10)(x+4)}[/tex]

A parallelogram is transformed according to the rule (x,y) → (x, y). Which is another way to state the
transformation?
Ro, 90°
Ro, 180°
Ro, 270°
Ro, 360°
Answer:
Ro, 360°
Step-by-step explanation:
Given
(x,y) transformed to (x,y)
Required
Determine the transformation
We have the following observations
Before transformation, the coordinates are: (x,y)
After transformation, the coordinates are: (x,y)
In other words, the coordinates before and after the transformation are the same.
This implies that there is a 360 degrees rotation.
Simply put, when there are no changes in the pre and post transformation of a point, line or shape, then the transformation is 360 degrees
The parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).
360 degrees rotation
For 360 degrees rotation, the coordinates before and after the transformation will be the same.
According to this rule, the transformation of (x,y) gives (x, y)
Thus, the parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

6 The manufacturer of an oven states that the
temperatures displayed while cooking are within a
5% error. Rachel is using the oven to cook a chocolate
cake that must be cooked at a temperature below
325°C. The oven display shows a temperature of 310°C.
Can Rachel be certain that the temperature is suitable
for cooking her cake? Explain your answer.
Result, Rachel can be certain that the temperature is suitable for her cake.
Rachel cannot be certain that the temperature displayed on the oven is suitable for cooking her cake.
The manufacturer's claim of a 5% error on the displayed temperature means that the actual oven temperature can be off by 5% in either direction. To calculate the range of possible actual temperatures, we need to find 5% of 310°C. 5% of 310 = (5/100) * 310 = 15.5°C This means that the oven temperature could be 15.5°C higher or 15.5°C lower than the displayed temperature.
To find the maximum possible temperature, we add the error to the displayed temperature: 310°C + 15.5°C = 325.5°C Since the maximum possible temperature is slightly above 325°C, Rachel cannot be certain that the temperature is suitable for cooking her cake, as it needs to be cooked at a temperature below 325°C. It's important for Rachel to consider using an alternative thermometer or verifying the actual temperature with the oven manufacturer to ensure the cake is cooked at the desired temperature.
