Mathematics
1 answer:
Phoenix [80]2 years ago
4 0

Answer:

Equilateral triangle: All three sides are equal.

Isosceles triangle: All two sides are equal.

Scalene triangle: No sides are equal.

Step-by-step explanation: Step 1: Label the given points as A, B, and C, and plot them as vertices of a triangle with connecting lines to draw the triangle we are working to identify.

Step 2: Calculate the side length AB using the distance formula.

Step 3: Calculate the side length BC using the distance formula.

Step 4: Calculate the side length AC using the distance formula.

Step 5: Compare the side lengths AB, BC, and AC from the previous steps to define the triangle type.

Suggested turkey cooking times at 180 degrees Celsius by weight:
Sonja [21]

Answer:

4kg : 45 x 4 + 20 = 200 minutes

5.5kg: 40 x 5.5 = 220 minutes

8kg: 35 x 8 = 280 minutes

The cooking time is directly proportional to weight in Turkey C

Hope this helps

Investigate the existence of a extrema value, what does the markered part mean?
OLga [1]

Answer: We have

f'(x) = a x + b,

f'(x) = 0 at x = -b/a

f(x) = a x^2 / 2 + b x + c


Meaning of marked part


❟ ∵ a<0 ❟ f is a quadratic function

∴ f has absolute maximum value at x = -b/a


For all a with a less than zero, f is a quadratic function. Therefore f has a global maximum at x = -b/a


That typesetting seems very sloppy. It probably is supposed to be


∀a < 0, f is a quadratic function.


The second sentence is sloppy in use of "absolute". It can't mean absolute value, so presumably it means "global".


Sometimes a minimum or maximum is only local, but a quadratic function has exactly one extrema, and it is global. And if a < 0, the extrema is a global maximum.


Step-by-step explanation:


An extrema (minimum or maximum) for f(x) occurs only where f'(x) = 0, that is, when the slope of the tangent at x is zero.


But if the function crosses its tangent at that point, the point is an inflection point, not an extrema. A quadratic never crosses it's tangent.

The graph of an exponential function has a y-intercept of 8 and contains the point (3,64). Find the exponential function that de
Brums [2.3K]

Given:

Y-intercept of exponential function is 8.

It contains the point (3,64).

To find:

The exponential function that describes the graph.

Solution:

The general form of an exponential function is

y=ab^x      ...(i)

where, a is initial value or y-intercept and b is growth factor.

Since, y-intercept is 8, therefore, a=8.

Put a=8 in (i).

y=8b^x         ...(ii)

It contains the point (3,64). Put x=3 and y=64.

64=8b^3

Divide both sides by 8.

\dfrac{64}{8}=b^3

8=b^3

2^3=b^3

On comparing both sides, we get

b=2

Put b=2 in (ii).

y=8(2)^x

The functions form of this equation is

f(x)=8(2)^x

Therefore, the required function is f(x)=8(2)^x.
