Answer:
Distance = 6.7 units
Step-by-step explanation:
Distance formula: [tex]d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]d = \sqrt{(8.5-8.5)^{2}+(2.2-8.9)^{2}} = \sqrt{(-6.7)^{2}} = 6.7[/tex]
Note that distance is always positive

Write the equation of the line with x-intercept 3 and passing through the point (5.4)
Answer: y=(1/5)m+3
Step-by-step explanation:
Start with the standard form of an equation of a straight line: y=mx+b, whre m is the slope and b the y-intercept (the value of y when x=0).
y=mx+b
We know b (3), so:
y=mx + 3
To find the slope, m, we can use the one given point, (5,4):
y=mx + 3 for (5,4) would be:
4 = m*5+3
1 = 5m
m = (1/5)
y=(1/5)m+3
Where ia the function decreasing?

The function is decreasing for x > -1
Step-by-step explanation:
How can you use factoring to solve quadratic equations in standard form?
Step-by-step explanation:
The roots or the zeroes of a quadratic equation are its x-intercepts, which are the points on the graph where it crosses the x-axis. When a quadratic equation is in standard form, ax² + bx + c, the usual goal is to find the binomial factors that could help us determine the roots or solutions to the given equation. Once you find the factors, then you will use the Zero-Product Property to solve for the solutions.
For example, if you were given the following quadratic equation in standard form, x² + 6x + 8 = 0, and were tasked to find its factors.
x² + 6x + 8 = 0
where a = 1, b = 6, and c = 8:
In order to find the factors of the given quadratic equation, we must find the factors with a product ac, and sum b.
Using 2 and 4 as possible factors produce a product that is equal to
product of ac: 2 × 4 = 8
sum of b: 2 + 4 = 6.
Therefore, the factors of the given quadratic equation, x² + 6x + 8 = 0 are:
(x + 2) (x + 4).
Using the Zero-Product Property, where it states that for any real numbers, u and v, if uv = 0, then u = 0 or v = 0.
Thus, setting the binomial factors of the given quadratic equation to zero will provide the solutions.
(x + 2) (x + 4)
x + 2 = 0
x + 2 - 2 = 0 - 2
x = -2
x + 4 = 0
x + 4 - 4 = 0 - 4
x = -4
Therefore, the solutions to the quadratic equation, x² + 6x + 8 = 0 are x = -2, and x = -4.
If n is an even number.
(b) What type of number is n + 1?
Answer:
An odd number
Step-by-step explanation:
suppose n is 2.
If we add 1 into it, the answer will be 3, making it odd. same goes for any other even number if 1 is added in it

How many gallons of a 50% antifreeze solution must be mixed with 90 gallons of 25% antifreeze to get a mixture that is 40% antifreeze? Use the six-step method.
Let x be the needed volume of 50% antifreeze solution. x gallons of this solution contains 0.50x gal of antifreeze.
Mixing this amount with 90 gal of 25% solution makes a total volume of (x + 90) gal of solution.
90 gal of 25% solution contains 0.25 (90 gal) = 22.5 gal of antifreeze.
The new mixture would then consist of (0.50x + 22.5) gal.
If its concentration of antifreeze is supposed to be 40%, then
(0.50x + 22.5)/(x + 90) = 0.40
Solve for x :
0.50x + 22.5 = 0.49 (x + 90)
0.50x + 22.5 = 0.49x + 44.1
0.01x = 21.6
x = 2160

Emmitt runs 5 miles in 40 seconds. How long will it take him to run 8 miles?
Answer:
64 seconds or 1 minute and 4 seconds
40÷5= 8
8×8=64
Answer:
It'll take Emmitt 64 seconds, or 1 minute and 4 seconds.
Step-by-step explanation:
set a proportion;
5 8
---- = ---
40 x
8/5 = 1.6
40 x 1.6 = 64
x = 64
a=V^2/P make v the subject
Answer:
correcto
Step-by-step explanation:
Answer:
v = sqrt(a*p)
Step-by-step explanation:
multiply both sides by p
a*p = v^2
square root both sides to get rid of the (^2) on the v
then you'll be left with v= sqrt(a*p)
On Monday, 339 students went on a trip to the zoo. All 6 buses were filled and 9 students had to travel in cars. How many students were
in each bus ?
Answer:tinham em cada onibus 55 alunos
Step-by-step explanation:
9 alunos tiveram que viajar de carro ,ou seja apenas 330 alunos foram de onibus , 339-9 igual a 330 .
Depois de conseguir esse resultado divida o numero de alunos (330) por numero de onibus (6) o resultado sera 55.
Find the midpoint of the line segment joining the points (-1,-1) and (-3,10).
Answer:
[tex](\displaystyle-2,\frac{9}{2} )[/tex]
Step-by-step explanation:
Hi there!
Midpoint = [tex](\displaystyle\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex] where the two endpoints of the line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the endpoints (-1,-1) and (-3,10):
[tex](\displaystyle\frac{-1+(-3)}{2} ,\frac{-1+10}{2} )\\\\(\displaystyle\frac{-4}{2} ,\frac{9}{2} )\\\\(\displaystyle-2,\frac{9}{2} )[/tex]

Step-by-step explanation:
Answer:
x = 12.633, -0.633
Step-by-step explanation:
x^2 -12x + 36 = 44
the underlined part is (x - 6) ^2
(x - 6)^2 = 44
(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)
(x - 6 ) = + 6.6332495807108
x = 12.6332495807108 = 12.633
(x - 6 ) = - 6.6332495807108
x = - 6.6332495807108 + 6
= -0.6332495807108 = -0.633

At a gathering of 15 people, there are 10 people who all know each other and 5 people who know no one. People who do not know each other shake hands. How many handshakes occur?
Answer:
Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.

Answer:
See answer below.
Step-by-step explanation:
1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot
there because this is your starting point.
2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and
closer to -2 because the point is -1 .75. Remember this point is not on the
graph.
3. Now move up from that point to 4.5 and put a dot at that place. The point is in the Q II , to the left top.

20% of A = 96
15% of B =75
Answer:
(20÷100)×96=19.2
(15÷100)×75=11.25
Answer:
A = 480
B = 500
Step-by-step explanation:
Find A and B??
.
20% of A = 96
[tex]\sf{20\% \times A = 96}[/tex]
[tex]\sf{ \frac{20}{100} \times A = 96}[/tex]
[tex]\sf{A = 96 \div \frac{20}{100} }[/tex]
