The length of the Akashi bridge is 13000 feet.

A fraction is a part of a whole.

It is expressed as a quotient, in which the numerator is divided by the denominator.

Example:

1/2, 4/5.

We have,

Golden Gate Bridge = 9000 feet

Akashi bridge = 1 and 4/9 times as long as Golden Gate Bridge

Here,

1 and 4/9 times can also be written as:

1 4/9 = 13/9 x 9000  

or

1 x 9000 + 4/9 x 9000

The length of the Akashi bridge:

= 1 x 9000 + 4/9 x 9000

= 9000 + 4 x 1000

= 9000 + 4000

= 13000 feet

Thus the length of the Akashi bridge is 13000 feet.

To show the negative of a square root, a negative sign would have to be placed outside the radical.

Answer:

Step-by-step explanation:

Because √-1 is an imaginary number √-1=i

Perimeter = 31.12

Step-by-step explanation:

The perimeter of the shape JKLM will be expressed as;

Perimeter = JK + JL + JM + KL + KM + LM

Using the formula for calculating the distance between two points;

D = √(x2-x1)²+(y2-y1)²

For JK where  J(-4,2) and K(1,2)

JK = √(1+4)²+(2-2)²

JK = √5²

JK =√25

JK = 5

For JK where  J(-4,2) and L(2,-2)

JL = √(2+4)²+(-2-2)²

JL = √6²+(-4)²

JL =√36+16

JL = √52

For JM where  J(-4,2) and M(-3,-2)

JM = √(-3+4)²+(-2-2)²

JM = √1²+(-4)²

JM =√1+16

JM = √17

For KL where  K(1,2), L(2,-2)

KL = √(2-1)²+(-2-2)²

KL = √1²+(-4)²

KL =√1+16

KL = √17

For KL where  K(1,2), M(-3,-2)

KM = √(-3-1)²+(-2-2)²

KM = √4²+(-4)²

KM = √16+16

KM = √32

KM = 4√2

For KL where  L(2,-2) and M(-3,-2)

LM = √(-3-2)²+(-2+2)²

LM = √(-5)²+(0)²

LM = √25

LM = 5

Perimeter = 5 + 4√2 + √17  + √17 + 5 + √52

Perimeter = 10 + 4√2 + 2√17 + √52

Perimeter = 10+5.66+8.25+7.21

Perimeter = 31.12

If Niki Brought a patio set on sale for $480 the original price was $850, then the rate of discount is 43.52%

Given,

The original price = $850

The selling price = $480

We know discount amount is the difference between the original price and selling price

Discount amount = Original price -  Selling price

Substitute the values in the equation

Discount amount =850-480

= $370

Then the discount percentage = (Discount amount ÷Original price )×100

Substitute the values in the equation

Discount percentage= [tex](\frac{370}{850})100[/tex]

=43.52%

Hence, if Niki Brought a patio set on sale for $480 the original price was $850, then the rate of discount is 43.52%

Using the t-distribution, it is found that since the p-value of the test is greater than the standard significance level of 0.05, the data refutes the manufacturer's claim.

At the null hypothesis, we test if there is not enough evidence that the mean is less than 10 minutes, that is:

[tex]H_0: \mu \geq 10[/tex]

At the alternative hypothesis, we test is there is enough evidence that the mean is less than 10 minutes, that is:

[tex]H_1: \mu > 10[/tex]

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

The values of the parameters are given as follows:

[tex]\overline{x} = 10.4, \mu = 10, s = 1.6, n = 20[/tex]

Hence the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{10.4 - 10}{\frac{1.6}{\sqrt{20}}}[/tex]

t = 1.12.

Using a t-distribution calculator, considering a left-tailed test, as we are testing if the mean is less than a value, with t = 1.12 and 20 - 1 = 19 df, the p-value is of 0.8617.

Since the p-value of the test is greater than the standard significance level of 0.05, the data refutes the manufacturer's claim.

The end behavior of the graph is  since the first end drops and the second rises in this case.

The degree and leading coefficient of a particular polynomial's graph will be used to analyze its final behavior.

The right answer is C: "[tex]2x^{7}[/tex] is the leading phrase. As an is positive and n is odd, the final behavior is down and up."

The general principle to remember is:

The polynomial's two arms move in the same direction if the degree is even, and both ends move upward if the leading coefficient is positive.

Both ends fall if the leading coefficient is negative.

Each end points in a separate directions if the degree is odd.

The first end (the one with the negative values) goes down and the other end goes up if the leading coefficient is positive.

The opposite occurs when the leading coefficient is negative.

This is the polynomial:

p(x)= [tex]2x^{7} -8x^{6} -3x^{5} -3[/tex]

The degree is 7, therefore it is odd, and the leading coefficient is positive, as can be seen (is equal to 2).

The correct response is C since the first end drops and the second rises in this case.

The compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000, the solution is 5 ≤ x ≤ 50 and all the solutions are viable

The given parameters are

Dimensions = 4x and 5

Area: 100 ≤ A ≤ 1,000

The area is calculated as

A = Product of dimensions

So, we have

A = 4x * 5

Evaluate

A =20x

Substitute A =20x in 100 ≤ A ≤ 1,000

100 ≤ 20x ≤ 1,000

So, the compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000

Divide through 100 ≤ 20x ≤ 1,000 by 20

5 ≤ x ≤ 50

Hence, the solution is 5 ≤ x ≤ 50 and all the solutions are viable

Answer:

The slope is -10, and the y-intercept is -1.

Step-by-step explanation:

The linear function is [tex]y=-10x-1[/tex].

The general form of a line is [tex]y=mx+c[/tex]

where

m = Slope of the line i.e., change of altitude divided by the change of the horizontal.

c = y intercept of the line i.e., the point where the line intersects the y axis.

Comparing with the given equation we get

[tex]m=-10[/tex] and [tex]c=-1[/tex]

So, the slope is [tex]-10[/tex], and the y-intercept is [tex]-1[/tex].
