Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.

What is the vertex of the function?

egoroff_w [7]

<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

$f(x)=3x^2-18x+33$

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

$V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33$

Therefore:

$x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6$

Therefore, the vertex is:

$\boxed{V(3,6)}$

In a survey of 2300 people who owned a certain type of car, 460 said they would buy that type of car again. What percent of the

JulsSmile [24]

Answer:

The survey shows that 20% of the individuals were satisfied with the car.

Step-by-step explanation:

We are given that 2,300 people were surveyed.
We are also given that 460 of those individuals would buy that car again.
We need to find the percentage of individuals that were satisfied with the car.

When we need to find the percentage of a population, we can use the following formula:

$\displaystyle \frac{\text{part}}{\text{whole}} \times 100$

We need to identify the part and the whole in this problem.

We are given that 2,300 people are surveyed, so this is the <u>whole</u> portion.

We are also given that 460 were satisfied, so this is the <u>part</u> portion.

Therefore, we can set up our fraction.

$\displaystyle \frac{460}{2300}$

Now, let's solve the percentage.

$\displaystyle \frac{460}{2300} \times 100\\\\\frac{2}{100} \times 100 = 20\%$

Therefore, of those surveyed, 20% of the individuals were satisfied with the car.

Answer:

x = 8.64

x = - 7.64

Both to 2 d.p

Step-by-step explanation:

Firstly, - 8 both side - cancels the +8 & get the surd to equal x - 8

Then, square root both side, to get:

x-2= x^2 - 64

+ 2 both side

x = x^2 - 66

-x

0= x^2 - 66 - x

x^2 - x - 66 = 0

general equation for quadratic is ax^2 + bx + c

Now, we can find the value of a, b, c using x^2 - x - 66 = 0

a=1

b= - 1

c= - 66

Now use quadratic formula

x = -b±√(b²-4ac))/(2a

= --1 + √ - 1 x - 1 - 4x1x-66 / 2x1

= 8.639.....

Now repeat with - b - & not - b +

x = -b±√(b²-4ac))/(2a

= --1 - √ - 1 x - 1 - 4x1x-66 / 2x1

= - 7.639.......
