Answer:

Usha is correct

Step-by-step explanation:

See attachment

Given

Dimension of the development

Height = \frac{1}{2}\ mile

Base = \frac{1}{2}\ mile

Dimension of a football field

Length = 100m

Width = 50m

First, we calculate the area of the development.

Because it is triangular in shape, the area is:

Area = \frac{1}{2} * Height * Base

Area = \frac{1}{2} * \frac{1}{2}mile * \frac{1}{2}mile

Convert mile to meter

Area = \frac{1}{2} * \frac{1}{2}* 1600m * \frac{1}{2} * 1600m

Area = \frac{1}{2} * 800m * 800m

Area = 400m * 800m

Area = 320000m^2

The area of 50 football pitch is then calculated as:

Area = 50 * Length * Width

Area = 50 * 100m * 50m

Area = 250000m^2

By comparison:

320000 > 250000

<em>Hence, Usha's thought is correct</em>

Question 1- explain how Sheldon immediately knew howard was incorrect?
Dmitrij [34]

Answer:

Part 1) In the procedure

Part 2) In the procedure

Step-by-step explanation:

Part 1) Observing the graph

The roots are x=-1/2 and x=4

Remember that, the roots are the x-values when the value of y is equal to zero (the x-intercepts)

That's why Sheldon immediately realizes Howard's solution is incorrect

Part 2) we have

y=2x^{2}-7x-4

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

equate the equation to zero

2x^{2}-7x-4=0  

so

a=2\\b=-7\\c=-4

substitute

x=\frac{-(-7)(+/-)\sqrt{-7^{2}-4(2)(-4)}} {2(2)}

x=\frac{7(+/-)\sqrt{49+32}} {4}

Howard's error is in this step, is wrong with the sign of the number 7, is positive instead of negative

x=\frac{7(+/-)\sqrt{81}}{4}

x=\frac{7(+/-)9}{4}

x=\frac{7(+)9}{4}=4

x=\frac{7(-)9}{4}=-1/2

pls help, no rush I just get really stressed when I don't know the answer to a problem, pls explain ur reasons :)
gtnhenbr [62]

9514 1404 393

Answer:

  2. correct

  3. addition property of equality

  4. substitution property of equality

Step-by-step explanation:

You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.

The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the <em>Addition Property of Equality</em>.

Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the <em>Substitution Property of Equality</em>.
