Which function is a quadratic function?P(x)=2x(×^2+6)+1
M(x)=-4(x+3)-2
t(x)=-8x^2(x^2-6+1
H(x)=3x(x-2)-4

Answers

Answer 1
Answer: The correct answer is:  [D]:  " H(x) = 3x(x - 2) - 4 " .
__________________________________________________
Note:  A "quadratic function" takes the form of:
__________________________________________________
     f(x)  =  ax²  + bx  + c ;
_________________________________________________
Answer choice:  [D]:  " H(x) = 3x(x - 2) - 4 " ; 

takes this form:
_________________________________________________
    " H(x) = 3x(x - 2) - 4 " ;  

→  " 3x(x - 2) - 4 " ; 

Note the "distributive property" of multiplication:
_________________________________________________

  a(b + c)  =  ab  +  ac ;  AND

  a(b -  c)  =  ab  -   ac ;
_________________________________________________
 
 → As such;

    " 3x(x - 2)  =  (3x * x)  -  (3x * 2)  = 3x² - 6x;

So, we can rewrite the expression:

→  " 3x(x - 2) - 4 " ;  

as:  →  " 3x² - 6x - 4 ; 

And the entire function as:

H(x) = 3x(x - 2) - 4 ; 

as:  

H(x) = 3x² - 6x - 4 ; 

Which takes the form of a "quadratic function" ; 

→ f(x) = ax² + bx + c ; 

in which:  a = 3 ;   b = - 6 ;  c = - 4 .

Answers

Step-by-step explanation:

\csc \theta \cos^(2)\theta +  \sin \theta = \csc \theta(1 - \sin^(2)\theta) +  \sin \theta

=   (\csc \theta -  \sin \theta) +  \sin \theta

=  \csc \theta

A restaurant wants to study how well its salads sell. The circle graph shows the sales over the past few days. If 35 of the salads sold were Caesar salads, how many total salads did the restaurant​ sell?

Answers

Answer:

50

Step-by-step explanation:

From the circle graph :

Salad sold :

Caesar = 70%

Garden = 16%

Taco = 14%

If 35 of the salad sold were Caesar ;

Then ; this means

70% = 35

Total salad sold %= (70+16+14)% = 100%

Let total sales = x

70% = 35

100% = x

Cross multiply :

70% * x = 100% * 35

0.7x = 35

x = 35 / 0.7

x = 50

Julian measures the distance he drives to work each day using the odometer on his car, which measures distance in miles, accurate to the nearest tenth of a mile. Using that measurement, he claims that the exact distance he drives to work is 11.7 miles. Use complete sentences to explain why Julian’s claim is incorrect.

Answers

The claim is incorrect because the car's odometer is not perfectly accurate. A 10-minute he can measure to an accuracy of 1 mile, but is prone to error due to wear, calibration, measurement error and other factors. Additionally, factors such as tire pressure and changes in road conditions can affect the accuracy of odometer readings.

What is odometer of car?

An odometer is an in-vehicle device that measures the distance traveled by the vehicle. Displays the total number of miles or kilometers the car has traveled since the car was manufactured or the odometer was last reset. This measurement is important for several reasons. B. To track vehicle maintenance schedules, estimate fuel consumption, and determine vehicle resale value. Odometers typically use mechanical or electronic components to measure the distance traveled by a vehicle and display the information on the dashboard. However, as mentioned earlier, the accuracy of odometer readings depends on a number of factors.

The sum of the lengths of is 24.62 cm. The length of is 3 cm and the length of is 17.8 cm. What is the length of and what kind of triangle is this?A. 3.82 cm; scalene
B. 3.82 cm; isosceles
C. 3.92 cm; scalene
D. 3.92 cm; isosceles

Answers

Answer:

the \: third \: length \:  \n 24.62 - 3 - 17.8 = 3.82 \n  \n because \n  \: 17.8 > 3 + 3.82 \n it \: is \: scalene

Scalene Triangle

A scalene triangle has all side lengths of different measures. No side will be equal in length to any of the other sides in such a triangle. In a scalene triangle, all the interior angles are also different.

Isosceles Triangle

In an isosceles triangle, the lengths of two of the three sides are equal. So, the angles opposite the equal sides are equal to each other. In other words, an isosceles triangle has two equal sides and two equal angles.

Answer:

B. 3.82 cm; isosceles

Plzzz help fast I need the answer

Answers

Answer: (The first number are the years and the second are the amount of Komodo's) (0, 0) (1, 4) (2, 20) (3, 100) (4, 500) (5, 2,500)

Step-by-step explanation:

If there are 4 Komodo's in the first year because that's when they moved in, then there would be zero in the 0 year.

If they keep multiplying their population by 5 each year then for every year, you would multiply the existing population of that year by 5

Starting at year 1 which is (1, 4)  multiply that by 5 to get 20 and so on to get the function.

I hope this helps!
