Answer:

Step-by-step explanation:

The set of integers consists of zero ( ), the positive natural numbers ( , , , …), also called whole numbers or counting numbers , and their additive inverses (the negative integers , i.e., −1, −2, −3, …). The set of integers is often denoted by a boldface Z ( ) or blackboard bold mathbb (Unicode U+2124 ℤ) standing for the German word Zahlen ( , numbers ).

Which equation below would be parallel to the line y= 2x+5 and pass through the point (3,1)

ki77a [65]

The answer is A, first the question said parallel so it should have same gradient and the gradient of the equation is 2 So eliminate D and bring (3,1) in each of the last three equation, and you will find just A conformed

Hi there, hope everyone is well and staying cool :D

Answer:

A) By using the Pythagorean Theorem, we will see that $8^2 + 15^2 = 17^2$ . If we simplify it, we will find that the hypotenuse of Δ $ABC = 17$

B) approximately $18.79$

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is $leg^2 + leg^2 = hypotenuse^2$

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, $8^2 + 17^2 = AD$ .

$8^2 + 17^2 = 64 +289$

$64 + 289 = 385$

$\sqrt{385} \\$ ≈ $18.79$

Hope you do well on the rest of your math problems :D

Use the information to answer the questions.

Anna71 [15]

Answer:

Part 1) The length of two sides and the measure of the included angle (Side-Angle-Side)

Part 2) $b^2=a^2+c^2-2(a)(c)cos(B)$

Part 3) $b=11.6\ in$

Step-by-step explanation:

we have

In the triangle ABC

$a=11\ in\\c=9\ in\\B=70^o$

Part 1) Which information about the triangle is given?

In this problem we have the length of two sides and the measure of the included angle (Side-Angle-Side)

see the attached figure to better understand the problem

Part 2) Which formula can you use ti find b?

I can use the law of cosines

$b^2=a^2+c^2-2(a)(c)cos(B)$

we have

$a=11\ in\\c=9\ in\\B=70^o$

substitute the given values

$b^2=11^2+9^2-2(11)(9)cos(70^o)$

$b^2=202-67.72$

$b=11.59\ in$

Part 3) What is b, rounded to the nearest tenth?

Remember that

To Round a number

a) Decide which is the last digit to keep

b) Leave it the same if the next digit is less than $5$ (this is called rounding down)

c) But increase it by $1$ if the next digit is $5$ or more (this is called rounding up)

In this problem we have

$11.59\ in$

We want to keep the digit $5$

The next digit is $9$ which is 5 or more, so increase the "5" by 1 to "6"

therefore

$b=11.6\ in$
