Answer:

Counter example to show that given conjecture is false.

Step-by-step explanation:

We are given a conjecture:

All mammals are monkeys.

We have to provide a counter example to show that this conjecture is false.

Since elephants are mammals, thus it will lie in the set of all mammals.

So we can write:

Elephants are monkeys which is false as it is obvious that elephants are not monkeys.

Hence, the given conjecture is false that all mammals are monkeys.

Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calcul

Marina86 [1]

To calculate the amount that Vince should pay back, we can use the formula of
A = P + PRT
where A is amount (unknown), P is principal ($900), R is rate of interest (1.5%).

Which in this case, Vince did follow the correct formula, but what he did wrong, it that he incorrectly changed the rate to a decimal. Instead, 1.5% should be 0.015 in decimal form.

So, the correct formula should be
A = 900 + 900(0.015x2)
A = 900 + 27
A = 927

So, the correct amount Vince should pay is $927.

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 70 meters above the road surf

goblinko [34]

Answer:

17.5 m

Step-by-step explanation:

The height of a parabola above its vertex is proportional to the square of the distance from the vertex.

<h3>Cable height</h3>

The towers are 1200 m apart, so each is 600 m from center. The location of interest is 300 m from center, so 1/2 the distance to a tower. Since the height is proportional to the square of the distance, the height half-way to the tower will be (1/2)² = 1/4 the height of the tower.

(1/2)²×(70 m) = 17.5 m

The height of the cable 300 m from center will be 17.5 meters.
