Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

12 = 1/2 (4) h

12 =2h

Divide each side by 2

12/2 = 2h/2

The value of b for which the quadratic equation x² - bx + 16 = 0 have exactly two different integer solutions is b > 8

An equation is an expression that shows the relationship between two or more numbers and variables.

A quadratic equation is in the form:

y = ax² + bx + c

Where a, b and c are constants.

If b² - 4ac > 0, then the equation have exactly two different integer solutions.

Given the equation:

x² - bx + 16 = 0, to have exactly two different integer solutions:

(-b)² - 4(1)(16) > 0

b > 8

The value of b for which the quadratic equation x² - bx + 16 = 0 have exactly two different integer solutions is b > 8

Answer:

n = 245

Step-by-step explanation:

The given sequence is 3,6,9,12,15,…

nth term of the AP is 735

We know that, the nth term of an AP is given by :

[tex]a_n=a+(n-1)d[/tex]

d is common difference, d = 6-3 = 3

Put all the values to find n.

[tex]735=3+(n-1)3\\\\732=(n-1)3\\\\\dfrac{732}{3}=n-1\\\\n=244+1\\\\n=245[/tex]

So, there are 245 terms in the sequence.

Answer:

Probability[Choosing red and blue consecutive] = 5/44

Step-by-step explanation:

Given:

Number of blue marble = 5

Number of green marble = 4

Number of red marble = 3

Find:

Probability[Choosing red and blue consecutive]

Computation:

Probability of red marble = Number of red marble / Total marble

Probability of red marble = 3 / [5 + 4 + 3]

Probability of red marble = 3 / 12

Probability of red marble = 1/4

Probability of next blue marble = Number of blue marble / [Total marble - 1]

Probability of next blue marble = 5 / [Total marble - 1]

Probability of next blue marble = 5 / [12 - 1]

Probability of next blue marble = 5 / 11

Probability[Choosing red and blue consecutive] = Probability of red marble x Probability of next blue marble

Probability[Choosing red and blue consecutive] = [1/4][5/11]

Probability[Choosing red and blue consecutive] = 5/44

the scale factor of RSTU to R'S'T'U' is 1/3

Step-by-step explanation:

look at the graph and count how many squares are needed for the line RS (3) and how many for the line R'S' (9).

this is 1:3 or 1/3

all other sides follow the same ratio.

the point P is diagonally one square down from S and 3 squares down from S'.

Answer:

0.057

Step-by-step explanation:

To obtain the p value, we need to obtain the test statistic :

For a one sample test :

Test statistic is given by :

(xbar - μ) ÷ (σ/√(n))

(185 - 175) ÷ (20/√(10))

10 ÷ 6.3245553

Test statistic = 1.581

Qe used the Z distribution because we are working with the population standard deviation.

Using the Pvalue from test statistic calculator :

Pvalue obtained using the Pvalue from Z statistic calculator, we obtain ;

Pvalue = 0.0569

Answer:

y= -2/8x + 3

Step-by-step explanation:

Step-by-step explanation:

The slope-intercept form of the equation is :

y =  mx+b

The given equation is :

-2x-8y= 24

Taking x term to RHS.

-8y = 24 +2x

Dividing both sides by -8

[tex]\dfrac{-8y}{-8} = \dfrac{24}{-8} +\dfrac{2x}{-8}\\\\y=-3-\dfrac{x}{4}\\\\or\\\\y=\dfrac{-1}{4}x+(-3)[/tex]

Hence, this is the required solution.

Answer:

A = 1/2 × b × h

A = 1/2 × 60 × 30

A = 1/2 x 900

A = 450

--------

A = 1/2 x 6 x 18

A= 1/2 x 54

A = 27

----------

27 + 450 = 477

=477

Step-by-step explanation:

Answer:

Derivative: P’(x) = 200 - 2x

If P’(x) = 0 , x = 100

Therefore P’ is positive and P increases until x = 100

So the maximum units to maximize profits is 100 units

And for 100 units the profit in dollar is:

Answer:

  x = 2 1/3

Step-by-step explanation:

We can examine the equations to see where the solution lies.

f(x) = (2/3) -x

This has an x-intercept where y=0, at x=2/3. It has a y-intercept where x=0, at y=2/3. Its slope is -1.

h(x) = 3 -2x

This has an x-intercept where y=0, at x=3/2. It has a y-intercept where x=0, at y=3. Its slope is -2.

__

In the first quadrant, the graph of h(x) is farther from the origin and steeper than the graph of f(x). The lines must cross in the 4th quadrant at some value of x that is greater than 3/2. The fraction in the definition of f(x) suggests that the solution will be a multiple of 1/3.

The attached table shows a couple of guesses at values of x that would make f(x) = h(x). We find that x = 7/3 is the solution we're looking for.

Square root of 0.028

Step-by-step explanation:

17% = 0.17

1/8 = 0.125 so it isnt in the inequality

1.7 is outside of the inequality

0.091 is out of the inequality

Square root of 0.028 = 0.167 (So it's in the inequality)
