Part A: The x-intercepts of the graph are (-2, 0) and (2.5, 0). 2x² - x - 10 = 0 2x² - 5x + 4x - 10 = 0 x(2x - 5) + 2(2x - 5) = 0 (x + 2)(2x - 5) = 0 x = -2, 5/2 or 2.5 Part B: The vertex is going to be the minimum of the function. The coordinates are (0.25, -10.125). Vertex = (h,k) h = midpoint of the x-intercepts (because of symmetry) h = (-2 + 5/2) = 1/4 k = f(1/4) k = 2(1/4)² - 1/4 - 10 = -81/8 Vertex: (0.25, -10.125). y-intercept: when x = 0 2(0)² - 0 - 10 = -10 Part C: To graph f(x), I would draw a line connecting the x-intercepts, vertex and the y-intercept using the points (-2,0), (0,-10), (0.25, -10.125) and (2.5,0). These points are the answers from part A and B and that is why I can use them to draw the graph.

A triangle formed by the sides 3.8cm ,3.7 cm, and 5cm is

Answers

It is a scalene triangle because none of the sides are the same!

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.

The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

How to find the type of triangle?

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,

For a triangle to be right angle triangle,

[tex]c^2=a^2+b^2[/tex]

By this law it is observed that,

For a triangle to be acute angle triangle,

[tex]c^2<(a^2+b^2)[/tex]

For a triangle to be obtuse angle triangle,

[tex]c^2>(a^2+b^2)[/tex]

The sides of the given triangle are 3.8 cm ,3.7 cm, and 5 cm.

Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,

[tex]c^2=5^2\\c^2=25[/tex]

Other two sides,

[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]

Therefore,

[tex]25<28.13\\[/tex]

Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

The length of a rectangular pool is 50 yards, and the width of the pool is 16 yards. What is the approximate length of the diagonal of the pool

Answers

Answer:

52.5

Step-by-step explanation:

You would use the Pythagorean theorem to solve this. Using the formula,

a^2 + b^2 = ^2

You would have an equation of 50^2 + 16^2 = c ^2.

50^2 is 2500, and 16^2 is 256.

There, you have 2500+256 = c^2

add those together, and you have 2756.

Now, you have to find the square root of 2756 (to solve 2756 = c^2)

which leaves you with 52.4976189936 . Rounded to the nearest tenth, you end up with 52.5.

Step-by-step explanation:

Step 1: Define

-84 = -2(2 + 5k)

Step 2: Solve for k

Divide -2 on both sides: 42 = 2 + 5kIsolate k term: 40 = 5kIsolate k: 8 = kRewrite: k = 8

Step 3: Check

Plug in k into the original equation to verify it's a solution.

Substitute in k: -84 = -2(2 + 5(8))Multiply: -84 = -2(2 + 40)Add: -84 = -2(42)Multiply: -84 = -84

Here we see that -84 does indeed equal -84.

∴ k = 8 is the solution to the equation.

From previous crops, he knows approximately how many ears of corn 10 plants will produce from the original seeds. The farmer decides to plant the new type of corn to determine if the seeds will produce a higher number of ears of corn. He plants the first 100 seeds of the new type of corn seeds in the field he uses for corn. When it is time to harvest, he randomly selects 10 plants and counts the number of ears. The farmer compares the number of ears with the yield he received the previous year from 10 plants using the original corn seeds. Because the new type of corn produced a higher number of ears, he concludes that the new type of corn does produce more ears of corn. Which of the following statements is not true about this experimental design?Because the farmer used the seeds from the top of the packet and did not randomly select the seeds, the conclusion is suspect.Because the farmer used a comparison between the yield of the new type of corn and the yield from the previous corn seeds, the conclusion is valid.There may be other variables that affected the yield of corn between this years crop and last years crop; therefore, the conclusion would be suspect.Because the farmer did not have two groups growing at the same time, one with the new type of corn and one with the original type of corn, the conclusion may be suspect.
