Answer:

C. 14cm

Step-by-step explanation:

The square of the longest line, in an obtuse triangle, is greater than the sum of the squares of the other two sides. So it is appropriate for equivalent legs to have a length

L^2 + l^2=2l^2

14^2+14^2=20^

196+196=400

392=400 400

The result:  14cm

Step-by-step explanation:

A) For the city of Everettt, y-intercept  represent the number of chrome books they started with.

y - intercept = 550

Everett started the 2016 year with 550 chrome books

B)  y = 50x + 300

Explanation: They stared with 300 books at 2016. This will be the y-intercept

Rate of change = 50 books per year which will the slope

m = 50 and b = 300

y = mx + b

y = 50x + 300

Hint:  y- intercept is where x-coordinate =0

This is just simple subtraction, 59.99 - 47.50

Answer: She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.

Step-by-step explanation:

GIven: Total documents needed to be done = 12

If she finished writing all documents by Friday, then the number of documents written on Friday = 12-(work done by Wednesday) - (work done on Thursday)

[tex]= 12 -(3\dfrac15)-(5\dfrac34)\\\\=12-\dfrac{16}{5}-\dfrac{23}{4}\\\\=\dfrac{12\times20-16\times4-23\times5}{20}\\\\=\dfrac{240-64-115}{20}\\\\=\dfrac{61}{20}\\\\=3\dfrac{1}{20}[/tex]

Hence, She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.

Answer:

As Jean writes 75,000,000 in scientific notation as 75.

This is INCORRECT!

The correct solution is:

75,000,000 in scientific notation: 7.5 × 10⁷

Step-by-step explanation:

As Jean writes 75,000,000 in scientific notation as 75.

This is INCORRECT!

Here is the correct solution:

Given the number

75,000,000

Let us write the number 75000000 in scientific notation

We know that scientific notation is of the form [tex]a\times 10^b[/tex] where [tex]1\le a<10[/tex] and b is an integer.

Move the decimal point to the left to create a new number from 1 up to 10.

[tex]a=7.5000000[/tex]

Count the number of times you moved the decimal point

b = 7

so

[tex]=7.5000000\times 10^7[/tex]

Remove the trailing zeros

[tex]=7.5\times \:10^7[/tex]

Therefore, we conclude that:

75,000,000 in scientific notation: 7.5 × 10⁷

Answer:

perpendicular

Step-by-step explanation:

a line is perpendicular to another line when m of one line is the negative or opposite reciprocal of the other. m= 2

the perpendicular lines for that would be 1/2 which is the reciprocal and then the opposite sign which is negative.

Answer:

The perimeter of square will be 18 units

Step-by-step explanation:

We are given that the coordinates of three vertices of a square A (-2 1/2 , 1 1/2), B (-2 1/2 -3), and C (2,1 1/2 )

When point D is placed on this perimeter.

We have to find the perimeter of the square.

First we have to find the side of square by using the distance formula

Distance formula

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Coordinates of A=(-5/2,3/2)

Coordinates of B=(-5/2,-3)

Length of side AB=[tex]\sqrt{(-5/2+5/2)^2+(-3-3/2)^2}[/tex]

Length of side AB=[tex]\sqrt{0+(-9/2)^2}[/tex]

Length of side AB=9/2 units

Now, the perimeter of square=4 (side)

Using the formula

Perimeter of square=4(9/2)=18 units

Answer:

1

Step-by-step explanation:

So first we do (x^5)^2 which we know is just x^10 because of exponents of powers I believe it's called, basically you just multiply the two powers.

Then you do the bottom half which is x^3 * x^7 and that equals x^10 because of the product of exponent rule,

Then we do x^10/x^10 which = 1 because the same number over the same number is always 1.

Let me know if you have any questions

Answer:

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Step-by-step explanation:

We need to solve the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex]

We know that exponent rule: [tex](a^m)^n=a^{m*n}[/tex]

Applying this rule in numerator

[tex]\frac{(x^5)^2}{(x^7)(x^3)}\\=\frac{(x^{5*2})}{(x^7)(x^3)}\\=\frac{(x^{10})}{(x^7)(x^3)}[/tex]

We know the exponent rule: [tex](a^m).(a^n)=a^{m+n}[/tex]

[tex]=\frac{(x^{10})}{x^{7+3}}\\=\frac{(x^{10})}{x^{10}}[/tex]

Now, using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

[tex]=x^{10-10}\\=x^0[/tex]

We know that [tex]a^0=1[/tex]

So, [tex]x^0=1[/tex]

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Answer: E only

Step-by-step explanation:

Had the test

The expressions are also equal to 1/3 is cos (90 -x).

These relations are valid for all the values of A that lies between 0° and 90°.

Given:

sin x = 1/3

Now, using property

sin [tex]\theta[/tex] = cos [tex]( 90- \theta)[/tex]

So, sin x= cos (90 -x)

Hence, The expressions are also equal to 1/3 is cos (90 -x).

Answer:

2 unique triangles

Step-by-step explanation:

We can only form two triangles

Since two of the sides are equal, we can form two isosceles triangles

The first one will have 10, 10 , the last side, then 40, 70 , 70 as the internal angles

Just note that the angles must add up to be 180 and that there are two equal angles as we are dealing with an isosceles triangle

The second form is 10, 10 , 40 , 40 and 100

Here, we have the 40 on the sides of the base of the isosceles triangle with the measure 100 being the last angle

The number of unique triangles that can be formed with he given parameters are; 2

We are told that;

Two side lengths of the triangle = 10 cm

One angle = 40°

Now, the two equal angles could be 40° each.

Thus;

Third angle of the triangle = 180 - 2(40) = 100°

(180 - 40)/2 = 140/2

>> 70°

Thus, we can make 2 unique isosceles triangles.
