Answer: yes it is a right angle triangle

Step-by-step explanation:

a^2 + b^2 = c^2

8^2+ 5^2 = ?

64 + 25 = square root of 89

square root of 89 = 9.4

when we round 9.4 it is 9

so

22- (8+5) =

22 - 13 = 9

so our answer is correct

Answer:

No, it isn't a right triangle

Step-by-step explanation:

AB+ BC + AC= 22            parts whole postulate

8 + 5 + AC = 22            substitution

AC= 22- 13= 9               Algebra

by judging the sides of triangle, we can tell that AC is the longest side therefore is would be the hypotenuse

AC= c

AB= a

CB = b

a^2 + b^2 = c^2       pythagorean theorem

8^2 + 5^2 = 9^2    substitution

64 + 25 = 81        Algebra

89 = 81

ABC is NOT a right triangle

I hope this helps!!!

Which is the distance from point A to B?
Aleks04 [339]

Answer:

D) radical 26

Step-by-step explanation:

So this is a question where you need to find the hypotenuse of a triangle

the sides are 1 and 5

you can use Pythagoras (a^2+b^2=c^2)

substitute the values in

1^2+5^2=c^2

simplify the exponents

1+25=c^2

add them together

26=c^2

take the square root of 26

the answer is radical 26

oksian1 [2.3K]

Step-by-step explanation:

An angle is a shape, formed by two lines or rays diverging from one common point (the vertex).

Answer: <em>Assuming it's not a 0° angle nor an 180° angle, the rays intersect in C) 1 point.</em>

[HELP] For j(x) = <img src="https://tex.z-dn.net/?f=5%5Ex%5E-%5E3" id="TexFormula1" title="5^x^-^3" alt="5^x^-^3" align="absmidd

The difference quotient of the function that has been presented to us will turn out to be 5.

<h3>How can I calculate the quotient of differences?</h3>

In this step, we wish to determine the difference quotient for the function that was supplied.

To begin, keep in mind that the difference quotient may be calculated by:

Lim h->0 \frac{f(x+h)-f(x)}{h}

Now, for the purpose of the function, we need this:

Then we will have:

$$\begin{aligned}&\lim _{h \rightarrow 0} \frac{j(x+h)-j(x)}{h} \\&\lim _{h \rightarrow 0} \frac{5 *(x+h)-3-5 * x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 x+5 h-3-5 x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 h}{h}=5\end{aligned}$$

j(x) = 5x - 3

Then the following will be true:

Therefore, 5 is the value of the difference quotient for j(x) is %

4(8x−1) = 19+32x
Fantom [35]

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

4 ( 8x − 1 ) = 19 + 32x

Step 1: Simplify both sides of the equation.

4 ( 8x − 1 ) = 19 + 32x

( 4 ) ( 8x ) + ( 4 ) ( −1 ) = 19 + 32x ( Distribute )

32x + −4 = 19 + 32x

32x − 4 = 32x + 19

Step 2: Subtract 32x from both sides.

32x − 4 − 32x = 32x + 19 − 32x

−4 = 19

Step 3: Add 4 to both sides.

−4 + 4 = 19 + 4

0 = 23

Answer:

There are no solutions.
