Answer:

Option 1: triangle HFG is congruent to triangle KIJ

Step-by-step explanation:

F and I are same as they are on 90 degrees.

In figure 1, from I to K is the height of the triangle.

In figure 2, from F to H is the height of the triangle.

Therefore, IK is congruent to FH

In figure 1, I to J is the base of the triangle from 90 degrees.

In figure 2, F to G is the base of the triangle from 90 degrees.

Therefore, IJ is congruent to FG

Therefore, triangle HFG is congruent to triangle KIJ.

The first option is correct.

Find the value of x at which the function has a possible relative maximum or minimum point. (Recall that e Superscript x is pos

shutvik [7]

Answer:

x= -11/4 is a maximum.

Step-by-step explanation:

Remember that a function has its critical points where the derivative equal zero. Therefore we need to compute the derivative of this function and find the points where the derivative is zero. Using the chain rule and the product rule we get that

$f'(x)= -e^{-4x}(11+4x)$

And then we get that if $11+4x = 0$ then $x = -11/4$ . So it has a critical point at $x = -11/4$ .

Now, if the second derivative evaluated at that point is less than 0 then the point is a maximum and if is greater than zero the point is a minimum.

Since

$f''(x) = 8e^{-4x} (5+2x)\\f''(-11/4) = -239496.56$

x= -11/4 is a maximum.

Write a division expression with a quotient that is: greater than 8÷0.001 less than 8÷0.001 between 8÷0.001 and 8÷110 does one b

Anna71 [15]

Answer:

9÷0.001 is greater than 8÷0.001.

7÷0.001 is less than 8÷0.001.

8÷0.002 lie between 8÷0.001 and 8÷110.

Step-by-step explanation:

The division expression which is greater than 8÷0.001 is:

9÷0.001

Since, the numerator of the number 9÷0.001 is greater than 8÷0.001. and as their denominator is same.

so, the number whose numerator is greater than the other will result in the overall number to be greater.

The division expression which is less than 8÷0.001 is 7÷0.001.

Since, for two numbers with same denominator the number whose numerator is smaller is smaller than the other.

The division expression that lie between 8÷0.001 and 8÷110 is: 8÷0.002.

Since 8÷0.002 is greater than 8÷110, as for two numbers with same numerator but different denominator the number whose denominator is greater is a smaller number.

similarly 8÷0.002 is smaller than 8÷0.001.

Which expression shows the result of applying the distributive property to 3(2x−6)3(2x−6) ?

sattari [20]

Here is the answer. Given <span>3(2x−6) 3(2x−6), what we need to do is multiply 3 by 2x and -6 and this will give us this result. 6x-18 6x-18. Therefore, the answer for this is the first option. The expression that </span>shows the result of applying the distributive property to 3(2x−6)3(2x−6) is 6x-18 6x-18.
