Work out the value of 5² - 19 x 24

Answer:

radius: 23 inches

Step-by-step explanation:

Formula: ∅r = arc length

Here the ∅ is 2 rads and arc length is 46 inches.

using the formula:

2*r = 46

r = 23 inches

The length of the chord CE is 24.46 in

To find the length of the chord CE, we solve the question using pythagoras' theorem

A chord is a line segment touching two points in a circle.

Pythagoras' theorem states that in any right angled triangle with sides a, b and c where c is the hypotenuse side, we have that

c² = a² + b²

Now form the diagram the radius of the circle BE forms a right angled triangle with the perpendicular to the chord, BO and the midway between the chord, OE.

BO = BD - OD

= 20 in - 5 in

= 15 in

From pythagoras,

BE² = DE² + BO²

making DE subject of the formula, we have

DE = √(BE² - BO²)

DE = √((20 in)² - (15 in)²)

DE = √(400 in² - 225 in²)

DE = √(175 in²)

DE = 13.23 cm

Since the chord CE = 2DE,

So, CE = 2 × 13.23 in

= 26.46 in

So, the length of the chord CE is 24.46 in

Step-by-step explanation:

If there are 4 real zeros, the polynomial degree must be at least 4.

The "fundamental theorem of algebra" says the number of polynomial zeros will be equal to the degree of the polynomial. If there are no complex zeros, then the degree will match the number of real zeros.

Answer:

8.4 grams

Step-by-step explanation:

We have $70 to start and someone us another $30 for a total of $100.  We pay $100 for 28 grams of seeds.  If we assume the peron giving us $30 wants a fair share of the seeds, we would calculate an average cost per gram and use that to determine the grams of seeds that the $30 would have covered.

($100/28 grams) = $3.57/gram

($30/$3.57/gram) = 8.4 grams

Answer:

28 grams of seeds

Step-by-step explanation:

(This question is a little tricky)

Note that:

{28 grams of seeds = $100}

----------------------------------------

You have $70 already, and then someone gives you $30.

It means $70 + $30 = $100

So you have $100 now, you can buy 28 grams of seeds and give the person that gave you $30.

The correct null and alternative hypotheses for the reporter's investigation are:

Null Hypothesis (H₀): The mean price of beef in the fall (μ_fall) is equal to the mean price of beef in the spring (μ_spring).

Alternative Hypothesis (H₁): The mean price of beef in the fall (μ_fall) is not equal to the mean price of beef in the spring (μ_spring).

Symbolically, it can be represented as:

H₀: μ_fall = μ_spring

H₁: μ_fall ≠ μ_spring

In this context, the null hypothesis assumes that there is no difference in the mean prices of beef between the fall and spring seasons. The alternative hypothesis suggests that there is a significant difference in the mean prices of beef between the two seasons.

The investigation aims to test whether the belief that grocery stores sell beef at a higher price in the fall compared to the spring is supported by the data. By conducting statistical analysis on the samples' mean and standard deviation, the reporter can evaluate whether there is evidence to reject the null hypothesis in favor of the alternative hypothesis.

A graph of this parallelogram is shown below.

The perimeter of a parallelogram is equal to 31.8 units.

In Mathematics and Geometry, the perimeter of a parallelogram can be calculated by using this mathematical equation (formula);

P = 2(L + W)

Where:

For the length, we have:

Distance UX = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance UX = √[(2 + 2)² + (3 + 5)²]

Distance UX = √80

Distance UX = 8.9 units

For the width, we have:

Distance WX = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance WX = √[(2 - 9)² + (3 - 3)²]

Distance WX = √49

Distance WX = 7 units.

P = 2(UX + WX)

P = 2(8.9 + 7)

P = 31.8 units.

Step-by-step explanation:

The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.

According to the statement

we have given that the df total = 29 and df within = 27. And we have to find the value of the df between.

So, For this purpose, we know that the

Analysis of variance (ANOVA) is an analysis tool used in statistics that splits an observed aggregate variability found inside a data set into two parts.

So, Df between values are the values between the value of dftotal and dfwithin.

Here df total = 29 and df within = 27

So, df between = df total - df within

Substitute the values in it then

df between = df total - df within

df between = 29 - 27

df between = 2.

So, The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.

Answer:

59049

Step-by-step explanation:

The pattern is that it multiplies by 3 every time.

9*3=27, and 27*3=81.

81*3 = 243

243*3 = 729

729*3=2187

2187*3=6561

6561*3=19683

19683*3 = 59049

a. To determine the price that should be charged if the demand is 40 million gallons, we need to substitute the given demand value into the price-demand equation and solve for p.

The price-demand equation is given as 0.2x + 2p = 60, where x represents the daily demand in millions of gallons and p represents the price per gallon in dollars.

Substituting x = 40 into the equation, we have:

0.2(40) + 2p = 60

8 + 2p = 60

2p = 60 - 8

2p = 52

p = 52/2

p = 26

Therefore, the price that should be charged if the demand is 40 million gallons is $26 per gallon.

b. To determine the decrease in demand resulting from a price increase of $0.5, we need to calculate the change in demand caused by the change in price.

The given price-demand equation is 0.2x + 2p = 60. Let's assume the initial price is p1 and the initial demand is x1. The new price is p2 = p1 + 0.5 (increase of $0.5), and we need to find the change in demand, Δx.

Substituting the initial price and demand into the equation, we have:

0.2x1 + 2p1 = 60

Now, substituting the new price and demand into the equation, we have:

0.2x2 + 2p2 = 60

To find the change in demand, we subtract the two equations:

(0.2x2 + 2p2) - (0.2x1 + 2p1) = 0

Simplifying the equation:

0.2x2 - 0.2x1 + 2p2 - 2p1 = 0

Since p2 = p1 + 0.5, we can substitute it in:

0.2x2 - 0.2x1 + 2(p1 + 0.5) - 2p1 = 0

0.2x2 - 0.2x1 + 2p1 + 1 - 2p1 = 0

0.2x2 - 0.2x1 + 1 = 0

Rearranging the equation:

0.2(x2 - x1) = -1

Dividing both sides by 0.2:

x2 - x1 = -1/0.2

x2 - x1 = -5

Therefore, the demand decreases by 5 million gallons when the price increases by $0.5.

The equation in standard form for the circle with center (5,0) passing through (5, 9/2) is 4x² + 4y² - 40x + 19 = 0

Given that

Center = (5, 0)

Point on the circle = (5. 9/2)

The equation of a circle can be expressed as

(x - a)² + (y - b)² = r²

Where

Center = (a, b)

Radius = r

So, we have

(x - 5)² + (y - 0)² = r²

Calculating the radius, we have

(5 - 5)² + (9/2 - 0)² = r²

Evaluate

r = 9/2

So, we have

(x - 5)² + (y - 0)² = (9/2)²

Expand

x² - 10x + 25 + y² = 81/4

Multiply through by 4

4x² - 40x + 100 + 4y² = 81

So, we have

4x² + 4y² - 40x + 19 = 0

Hence, the equation is 4x² + 4y² - 40x + 19 = 0

The least Alicia spent per yard on 10 yards of plaid fabric is $1.355.

What is the ratio?

A ratio is a mathematical comparison of two or more quantities that indicates how many times one value contains another.

We can start by finding out how much Alicia spent on the calico fabric:

5 yards of calico at $1.99 per yard = $9.95

We know that Alicia spent at least $23.50 on both the calico and plaid fabric, so we can subtract the amount she spent on the calico from $23.50 to find the minimum amount she must have spent on the plaid fabric:

$23.50 - $9.95 = $13.55

To find the least she spent per yard on 10 yards of plaid fabric, we can divide the total amount she spent on the plaid fabric by the number of yards:

$13.55 ÷ 10 yards = $1.355 per yard

Hence, the least Alicia spent per yard on 10 yards of plaid fabric is $1.355.

The length of the rectangle is 8 feet given it is 7 feet wide and has an area of 56 square feet.

A rectangle is a geometric figure with four straight sides and four right angles, where the opposite sides are parallel and equal in length. In this case, we are given that the rectangle has a width of 7 feet and an area of 56 square feet. The area of a rectangle is calculated by multiplying its length (L) and width (W), expressed as A = L × W.

We are provided with the width, W = 7 feet, and the area, A = 56 square feet. To find the length of the rectangle, we can rearrange the area formula:

L = A ÷ W

Substituting the given values, we have:

L = 56 ÷ 7

L = 8 feet

Hence, the length of the rectangle is 8 feet. To summarize, a rectangle with a width of 7 feet and an area of 56 square feet has a length of 8 feet. The dimensions of the rectangle are 7 feet by 8 feet.

P = x + 3x - 4 + 3x - 4 = 7x - 8

given P = 55 m , then equating

7x - 8 = 55 ( add 8 to both sides )
