Step-by-step explanation:

½*b*h = area of ∆

½*2h*h = 256

h² = 256

therefore, h = √256

h = 16m.

Answer:

16km

Step-by-step explanation:

The area formula for a triangle is ...

A = (1/2)bh

We are told that b=2h, so this becomes ...

 A = (1/2)(2h)(h) = h²

Substituting the given area, we can find h:

 256 km² = h²

 (√169) km = h = 16 km

The system random sampling involves the introduction of a sampling interval during the sampling process. Hence, the use of a fixed interval is more likely to miss the potential defect noticed based on the sampling interval selected.

Therefore, with simple random sampling, Sergio stands a better chance of capturing the defect better than using systematic random sampling

Rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]

Step-by-step explanation:

We need to rearrange the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject.

[tex]x=\frac{2w+1}{5-3w}\\x(5-3w)=2w+1\\5x-3wx=2w+1\\[/tex]

Subtract 2w on both sides

[tex]5x-3wx-2w=2w+1=2w\\5x-3wx-2w=1\\[/tex]

Subtract 5x on both sides

[tex]5x-3wx-2w-5x=1-5x\\-3wx-2w=1-5x\\[/tex]

Taking w common on left hand side

[tex]w(-3x-2)=1-5x\\[/tex]

Divide both sides by -3x-2

[tex]\frac{w(-3x-2)}{-3x-2} =\frac{1-5x}{-3x-2}\\w=\frac{1-5x}{-3x-2}[/tex]

So, rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]

Answer:

Step-by-step explanation:

The drawing is a bit unfortunate, as it does not show the angles true to size.

__

When the altitude (EG) of a triangle (∆DFG) is also a median, then that triangle is isosceles. Both halves are congruent right triangles.

  ∆GED ≅ ∆GEF

Since these are right triangles, the acute angle not given (∠EGF) is the complement of the one that is given.

  m∠EGF = 90° -m∠F = 90° -40°

  m∠EGF = 40°

__

Of course, angle D in ∆GED is identical to its counterpart in ∆GEF, angle F, so ...

  m∠D = 40°

__

Because the lines are parallel, angle ABE corresponds (and is congruent) to angle DEG, which is marked as a right angle.

  m∠ABE = 90°

The speed of the car was 33.5 miles per hour on the road on the basis of the skid mark it leaves behind on the road.

Given that, when a driver applies the brakes, then the tires lock but the car continue to slide, and leaves a skid mark on the road. By using the length of the skid mark we can approximate the speed of the car by which it was travelling on the road. The formula which we will be using to approximate the speed = √30 × Length of the skid mark × 0.75, where the speed is measured in miles per hour and the length is measured in feet.

Length of the skid mark on the road = 50 feet

speed of the car = √30 × Length of the skid mark × 0.75

simply put the value of length of the skid mark in the above formula and solve accordingly.

=√30 × 50 × 0.75

=√1125

=33.5

∴ The speed of the car was 33.5 miles per hour when it was on the road and leave behind a 50 feet skid mark on the road.

Answer:

15 blue marbles

Step-by-step explanation:

Given that:

A bag contains 6 red marbles.

The Ratio of red to  blue marbles is 2:5

Thus, the ratio of red marbles for 6 red marbles in a bag will be = 6/2 = 3

Now; the ratio of blue marbles in a bag containing 6 red marbles = 3 × 5 = 15 blue marbles

OR

Mathematically;

[tex]\dfrac{2}{5} \times \dfrac{x}{x} = \dfrac{6}{blue}[/tex]

So, we are looking for the same number we can multiply for both the numerator and the denominator that can give us the value of 6 in the above numerator to determine the value of the denominator. If we use 3 since 2× 3 = 6

We have:

[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{blue}[/tex]

[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{15}[/tex]

So, there are 15 blue marbles in the bag.

Answer:

Step-by-step explanation:

Answer: 16,250 units.

Step-by-step explanation:

This is a linear function which means that it takes the form of y = mx + c.

Y is the demand

X is the price

Find m.

= (Y₂ - Y₁) / (X₂ - X₁)

= (15,000 - 20,000) / (60 - 40)

= -250

Find c using substitution;

20,000 = -250 * 40 + c

20,000 = -10,000 + c

c = 20,000 + 10,000

c = 30,000

Linear function is;

y = -250x + 30,000

If selling price is $55;

y = -250 * 55 + 30,000

y = 16,250 units.

The demand is 17000 units when the selling price is $55 per unit

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let Q represent the demand and P represent the selling price.

20000 units for selling price of $40, hence (40, 20000). 16000 units for selling price of $60, hence (60, 16000).

Hence:

[tex]Q-Q_1=\frac{Q_2-Q_1}{P_2-P_1}(P-P_1)\\\\Q-20000=\frac{16000-20000}{60-40}(P-40)\\\\Q=-200P+28000[/tex]

For P = 55 unit:

W

Q = -200(55) + 28000 = 17000

The demand is 17000 units when the selling price is $55 per unit

Answer:

3/2

Step-by-step explanation:

Use the slope formula:

m = (y2-y1)/(x2-x1)

m = (5-(-4))/(2-(-4))

m = 9/6

m = 3/2

To find the answer to this question, all we need to do is use the slope formula!

Slope formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

(-4, -4) is [tex]x_{1} y_{1}[/tex]

and

(2,5) is [tex]x_{2} y_{2}[/tex]

Now lets plug in the points

[tex]\frac{5- (-4)}{2- (-4)}[/tex]

solve this simple subtraction problem!

5 - (-4) = 9

2 - (-4) = 6

Now we have : [tex]\frac{9}{6}[/tex]

Let's simplify since 9 and 6 both have a common factor of 3

Your final answer is...

The slope of the line passing through the points is [tex]\frac{3}{2}[/tex] !!

For a quadratic equation, we start out seeking 2 solutions.

According to the statement

We have to find about the quadratic equation.

So, For this purpose, we know that the

Quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power

From the given information:

when we solve a quadratic equation, how many solutions should we always start out seeking.

Then

Here, we are required to search out out what number solutions to start out out seeking while solving a equation and also the condition for a quadratic graph not having zeros ( no x-intercepts).

Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.

And, a quadratic can haven't any zeros ( no x intercepts) if the roots of the equation are complex numbers.

A quadratic is one which has the very best degree of its variable ( usually x) to be 2.

Consequently, after we solve a quadratic, one should start out seeking two (2) solutions.

This is so because, the quantity of solutions to begin out seeking corresponds with the very best power of the experimental variable, X.

Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.

Therefore, where X¹ occurs in an equation, it's linear and consequently has 1 solution.

And, where X² occurs in an equation, it's quadratic and consequently has 2 solutions.

It is possible to possess a quadratic with no zeros (i.e no x-intercepts).

So, For a quadratic equation, we start out seeking 2 solutions.

The factor of the given equation; -2x⁴-34x³-140 is (x³ + 10)(x + 7).

Factorization is the process of dividing a large number into smaller numbers that, when multiplied together, yield the original number.

Now, as per the stated question;

Quartic Equation: The general quartic equation has an analogous formula: ax⁴ + bx³ + cx² + dx + e = 0. This really refers to four different formulas, each of which yields one root of a equation.

The given quartic equation is -2x⁴-34x³-140.

Divide the complete equation by -2.

= x⁴ + 17x³ + 70

Find the factors of 0 such that on addition it given 17.

=  x⁴ + 10x³ + 7x³ + 70

Taking x common

= x(x³ + 10) + 7(x³ + 10)

Taking (x³ + 10) common,

= (x³ + 10)(x + 7)

Therefore, the factors of the given quartic equation is found as: (x³ + 10)(x + 7).
