What assumption should be made to prove this conjecture by contradiction? If it is raining, then I will not go swimming.

1 answer:

8 0

Here are some options to make deciding easier-

A) you went swimming
B) it is raining
C)you are not swimming
D) it is not raining

I think that the answer would be A because the opposite of it not raining would be it raining and the effect of that is that you will go swimming.

Hope this helps... plz mark Brainliest :)

Write two polynomials with a difference of 2x2 + x + 3

Anettt [7]

Answer:

The two polynomial CAN be $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

Step-by-step explanation:

Step 1: Simplify the expression:

$2*2 + x + 3$

$4+x+3$

$x+7$

Step 2: Think of a random polynomial:

$5x^4+5x^3+8x^2+x+6$

Step 3: Either add your "random polynomial" by $x+7$ or subtract it.

I want to add it so...

$5x^4+5x^3+8x^2+x+6+x+7$

= $5x^4+5x^3+8x^2+2x+13$

Check by subtracting $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

$5x^4+5x^3+8x^2+2x+13$

- $5x^4+5x^3+8x^2+x+6$

_____________________

$0x^4 - 0x^3 -0x^2 +x +7$ or  $x+7$

Alice's grandmothers age is a composite number between 70 and 80 and has a factor of 11 what is it

pshichka [43]

The factor of 11 is going to be 77 because you have to stay in between 70 to 80

and 7 times 11 is 77. It also has to be a number in the 11 timetables. It can't be 88 because we can't cross 80 so the factor is going to be 77.

Hope it helps

Convert the function into intercept form. Show your work. y=-x^2+5x+36

UkoKoshka [18]

Y = -x2 + 5x + 36 → y = -(x2 -5x -36)

→ y = -(x2 - 9x +4x - 36)

→ y = -[x(x-9) + 4(x - 9)]

→ y = -(x - 9)(x + 4)

Your answer would be y=-(x-9)(x+4).

To find the area of a triangle, you multiply the base times the height and multiply it by 2.
In order to find the height, you need to do this in reverse.
1.multiply 24x2
2. Find possible multiples.
3. 4x12=48, 12(the base) is three times four, and 48/2 is 24.
Answer: the height of the triangle is 4
