KF = 8 units

m∠DFE = 90°

-

We know that DK is 16 so you would just have to divide it by 2

[tex]\frac{16}{2} =8[/tex]

-

Since EF is a bisector, split it right down the middle means it will be equal to 90 degrees.

Any quadratic function whose leading coefficient is greater than 1 is narrower than [tex]h(x) = x^2[/tex].

The function [tex]h(x) = x^2[/tex] belongs to the family [tex]y = a\cdot x^{2}[/tex], where [tex]a[/tex] is a real coefficient. The greater the [tex]a[/tex], the narrower the graph. Hence, any function whose leading coefficient is greater than [tex]a[/tex] presents a narrower form, that is, [tex]y[/tex] shows greater values for a given value of [tex]x[/tex].

The solution to the trigonometric expression is given by [tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2}) =-\sqrt{\frac{3}{2} }[/tex]

An equation is an expression used to show the relationship between two or more variables and numbers. Trigonometric functions are specific functions of angles. Examples are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Given the equation:

[tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2} )\\\\tan(-\frac{2\pi}{3})=\sqrt{3} \\\\tan(\frac{7\pi}{4})=-\sqrt{2} \\\\tan(-\frac{\pi}{2})=0\\\\\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2} )=\frac{\sqrt{3} }{-\sqrt{2} }=-\sqrt{\frac{3}{2} }[/tex]

The solution to the equation is [tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2}) =-\sqrt{\frac{3}{2} }[/tex]

We can factorize abcabc as

abcabc = abc000 + abc

abcabc = abc (1000 + 1)

abcabc = abc × 1001

abcabc = abc × 7 × 11 × 13

so naturally each of 7, 11, and 13 must divide abcabc.

Answer:

28.5714285714286 cm

Step-by-step explanation:

1 L = 1000 mL

1 L = 1000 cm^3

60 L = 60,000 cm^3 (multiply both sides by 60)

The cooler has volume of 60,000 cubic cm. Let V = 60000

Assuming the cooler is a rectangular prism (aka a block), then we can say

volume = length*width*height

V = L*W*H

60000 = 60*35*H

60000 = 2100H

2100H = 60000

H = 60000/2100

H = 28.5714285714286 which is approximate

And the surface area (SA) is

SA = 2*(LW + LH + WH)

SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)

SA = 9628.57142857143 which is also approximate

Units for the surface area are in square centimeters.

would multiply everything by the common denominator of 4

-3/4m - 1/2 = 2 + 1/4m....multiply everything by 4 and u get :

-3m - 2 = 8 + m

that will get rid of the fractions....but u could multiply by -4 ...giving u :

Answer:

39 ft²

Step-by-step explanation:

I assume the base is a square 3 ft by 3 ft, and the height of each triangular side is 5 ft.

SA = s² + 4 × bh/2

SA = (3 ft)² + 4 × (3 ft)(5 ft)/2

SA = 9 ft² + 30 ft²

SA = 39 ft²

A statement that best compares the average values of the number of fish caught at both lakes daily:

There is a significant difference between the sample means.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.

The mean number of catfish caught daily at Lake Martin is 85,

with the number of catfish ranging from 75 to 140.

The mean number of catfish caught daily at Smith Lake is 104,

with the number of catfish ranging from 96 to 183.

The difference in all the sample means,

104 - 85 = 19.

Therefore, the difference is 19.

Answer:

3/50

Step-by-step explanation:

First,convert the 0.8kg to grams

To do this, first state formula 1kg equals 1000g

Solution

1kg equals 1000g

thus,0.8kg equals 0.8 x 1000g which further equals 800g

Since both are now in grams,they can be divided without many problems so

48g/800g,using 8 to divide through & grams cancelling out

6/100,using 2 to divide through finally becomes

Answer:

y=mx+b

Points are in (x,y) form so 5 is x and -6 is y

We know m = -1/7 (because m is slope)

So we can plug these values in to find b.

So:

-6 = 5(-1/7) + b

-6 = (-5/7) + b

-6 + 5/7 = b

b = -37/7

The central metaphor which is presented in six degrees of separation is:

This refers to the figure of speech which makes use of comparison to show the similarity between two different things.

With this in mind and from the concept of six degrees of separation, we can see that it is based on the theory that people are about six or fewer connections away from each other.
