Mathematics
1 answer:
marta [7]2 years ago
6 0

Answer:

No it is not a solution

Step-by-step explanation:

To solve this, you should replace your (x,y) with (8,3)- 8 being your x value and 3 being your y value.

So this inequality, your y value is supposed to be bigger than the value of whatever 3x-4 equals.

So, your inequality should be 3>3(8)-4

3*8=24-4=20

So is 3>(greater than)20? No. Which then means that (8,3) is not a solution because it would make the inequality not true.

Hope this helps!

Is f(x)=e^2 an exponential function? If so what is its base? If not, why?
makkiz [27]

Answer:

No. It is a constant function.

Step-by-step explanation:

The function f(x) = e^2 is not an exponential functional. Rather, it is a constant function. The reason for this is that in f(x) = e^2, there is no x involved on the right hand side of the equation. The approximate value of e is 2.718281, and the approximate value of 2.718281^2 is 7.389051. This means that f(x) = e^2 = 7.389051. It is important to note that for any value of x, the value of the function remains fixed. This is because the function does not involve the variable x in it. The graph of the function will be a line parallel to the x-axis, and the y-intercept will be 7.389051. For all the lines parallel to x-axis, the value of the function remains the same irrespective of the value of x. Also, the derivative of the function with respect to x is 0, which means that the value of the function is unaffected by the change in the value of x!!!

Polygon ABCD is a rectangle what is the area
Andre45 [30]

Solution:

As, You have Written Polygon ABCD is a rectangle.

It is a Four sided Polygon , having all it's interior angles equal to 90°.As well as Opposite sides are equal(AB=CD,AD=BC), equal diagonals(AC=B D).

Join any of the diagonal of Rectangle either AC or B D.

In Right Δ ABC , Right angled at B

{\text{Area (Right triangle ABC)}} =\frac{1}{2}\times AB \times BC---(1)

In Right  Δ ADC  , Right angled at D      

{\text{Area (Right triangle ABC)}} =\frac{1}{2}\times AD \times DC---(2)

Adding (1) and (2) that is LHS to LHS and RHS to RHS

Ar( Δ ABC) +Ar( Δ ADC)=\frac{1}{2}\times[ AB \times BC+ AD \times DC]\\\\=\frac{1}{2}[2 \times AB \times BC][\text{As, AB=CD, and BC=AD}]\\\\ = AB \times BC

So, Area of Rectangle= Product of any two Adjacent Sides

What is the missing angle? Please provide an explanation.
irina [24]

Answer:

64 degrees

Step-by-step explanation:

Lets find the measure of the other angle in the other triangle with measures of 84 and 36.

Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:

84 + 36 = 120

180 - 120 = 60

So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90

90 - 60 = 30

So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.

86 + 30 = 116

180 - 116 = 64

So the missing angle has a measure of 64 degrees

The sides of a rectangle are in the ratio 2:5. The perimeter of the rectangle is 70 cm. What is the width of the rectangle?
EleoNora [17]

Width = 10cm

Length = 25cm

<u>Explanation: </u>

Given, width:length = 2:5

Let width = 2x ,

So, length = 5x

Perimeter of rectangle = 2x(length + width)

According to the question,

70cm = 2X(5x + 2x)\\70cm = 2X(7x)\\35cm = 7x\\x = 5cm

Hence,

Width = 10cm

Length = 25cm
