Will the following side lengths make a triangle? 7, 5, 4

Greeley [361]

Okay too answer this you have to take the two smallest numbers and add them, in this case the answer would be 5 + 4 = 9. The answer has to be greater than the last number, In this case, 7. So the answer is yes.

What are the zeros of this function?

BabaBlast [244]

Answer:

x = 0 and x = 6

Step-by-step explanation:

See the graph attached to this question.

It is clear from the graph that the curve touches x-axis i.e. y becomes zero at points x = 0 and x = 6

Therefore, the give parabola has zeros at x = 0 and x = 6. (Answer)

Zeros of a function y = f(x) are determined from the equation f(x) = 0 and solving it we will get the x-values which are the zeros of the function.

In a chess variant, a "lord" can move one space at a time, either upward, or to the right, or diagonally up and to the right. ho

valentina_108 [34]

There are 48639 ways for a lord to move from the bottom left to top right corner of the 8 by 8 chessboard

<h3>Further explanation</h3>

The probability of an event is defined as the possibility of an event occurring against sample space.

$\large { \boxed {P(A) = \frac{\text{Number of Favorable Outcomes to A}}{\text {Total Number of Outcomes}} } }$

<h2>Permutation ( Arrangement )</h2>

Permutation is the number of ways to arrange objects.

$\large {\boxed {^nP_r = \frac{n!}{(n - r)!} } }$

<h2>Combination ( Selection )</h2>

Combination is the number of ways to select objects.

$\large {\boxed {^nC_r = \frac{n!}{r! (n - r)!} } }$

Let us tackle the problem.

This problem is similar to Pascal Triangle.

The Lord can move to the right or up in one way only.

We can put "1" in each box on the bottom and left to represent 1 possible movement.

To get the possibility of movement to another box, we will add the possibility of movement to the left, right, and diagonal squares as shown in Figure 1.

This process is repeated for the next box as shown in Figure 2.

Finally, after this process is repeated until the top right box, we get the results as shown in Figure 3.

There are 48639 ways for a lord to move from the bottom left to top right corner of the 8 by 8 chessboard.

Which ordered pair is the best estimate for the solution to the system

Vera_Pavlovna [14]

Answer:

The best estimate of the solution ordered pair from the graph is $(\frac{1}{2},0)$ .

Step-by-step explanation:

See the attached graph to this question.

The graph of two straight lines are shown in the graph.

Now, the two straight lines intersect on the x-axis, so the solution ordered pairs should have y-value equals to zero.

But, there are two ordered pairs with y-value zero and they are $(\frac{1}{2},0)$ and $(\frac{1}{3},0)$ .

The best estimate of the solution ordered pairs from the graph is $(\frac{1}{2},0)$ .

So, this is the solution. (Answer)

Marisol rode her bicycle each day for five days. estimate how far she biked in all. round each number to the nearest whole numbe

o-na [289]

Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.

<h3>How to round numbers?</h3>

The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.

Now, let's round the distance covered by Marisol each day:

Monday: 12.3 = 12
Tuesday: 14.1 = 14
Wednesday: 17.7= 18
Thursday: 11.8 = 12
Friday: 15.2 = 15

<h3>What distance did Marisol covered?</h3>

To know this just add the distance every day:

12 + 14 +18 + 12 + 15 = 71 miles

<h3>How much more did she bike on Wednesday than on Thursday?</h3>

Distance covered on Wednesday - distance covered on Thursday

18 - 12 = 6 miles

Note: This question is incomplete; here is the missing information:

Monday 12.3
Tuesday 14.1
Wednesday 17.7
Thursday 11.8
Friday 15.2
