The population of a city increases by 4.7% per year. If this
year's population is 77,000, what will next year's population
be, to the nearest individual?

There are 180 degrees in a triangle

4. 38+38= 76 degrees

180-76=104

Isosceles, Obtuse

5. 65+ x+x=65

Well we know one of the x

It is 90 degrees because it is a right angle

65+90=155

180-155=25

Scalene, Right triangle

6. 71+45= 116

180-116=64

7.  Scalene, acute

8. 126+22=148

180-148=32

Scalene, Obtuse

9. 50+90=140

180-140=40

Right angle,  Scalene

Answer:

Up.

Step-by-step explanation:

The  squared term is x and its coefficient (4) is positive.

Answer:

[tex]\displaystyle \sec(\theta)=\frac{9\sqrt{17}}{17}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \sin(\theta)=\frac{8}{9}\text{ and } \tan(\theta)>0[/tex]

And we want to find sec(θ).

First, note that both sine and tangent are positive. The only quadrant in which this can occur is QI. Hence, all trig ratios will be positive.

Also, recall that sine is the ratio of the opposite side to the hypotenuse. Using this information and the Pythagorean Theorem, we can determine the adjacent side:

[tex]a=\sqrt{9^2-8^2}=\sqrt{17}[/tex]

So, with respect to θ, the adjacent side is √(17), the opposite side is 8, and the hypotenuse is 9.

Secant is the ratio of the hypotenuse to the adjacent. Hence:

[tex]\displaystyle \sec(\theta)=\frac{9}{\sqrt{17}}=\frac{9\sqrt{17}}{17}[/tex]

Again, since θ is in QI, all trig ratios are positive.

Answer:

A is the answer because

12.45 + t = 16.0

or, t=16.0-12.45

so, t=3.61

=======================================================

Work Shown:

y = 4x+5 .... start with equation B

x+1 = 4x+5 .... replace y with x+1, due to equation A

The second step used the substitution property.

------

Alternative Viewpoint:

The variable y is equal to both 4x+5 and x+1 at the same time; therefore, the two right hand sides must be the same.

It's like saying if y = x and y = 5, then x = 5.

Answer:

–x² + 12x + 5

Step-by-step explanation:

x² + 3x

–2x² + 9x + 5

The sum of the above expression can be obtained as follow:

.... x² + 3x

+ –2x² + 9x + 5

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

–x² + 12x + 5

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

Thus, the sum of x² + 3x and –2x² + 9x + 5 is –x² + 12x + 5

Answer:

71.5

Step-by-step explanation:

You have to break it down into 3 different triangles. The area formula for a triangle is A = 1/2 * b * h.

Triangle 1: A = 1/2 * 10 * 4 = 20

Triangle 2: A = 1/2 * 11 * 5 = 27.5

Triangle 3: A = 1/2 * 6 * 8 = 24

Now add all your totals together, 20+27.5+24 = 71.5

Answer:

d. 63%

Step-by-step explanation:

percent, will be white?

A41% b50% c59% d63%

The probability of white = P (w) = 41/65= 0.63

The  probability of yellow = P (y)= 24/65= 0.369=0.37

The probability of choosing white is 0.63 . When rounded to  nearest percent gives

0.63*100/100

=0.63*100 percent

= 63 percent

= 63%

the probability of getting   the next marble white is the same as the probability of getting a white.

Answer:

Step-by-step explanation:

The slope can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

Using the first two table entries, this is ...

  m = (5 -4)/(-1 -(-2)) = 1/1

  m = 1

The y-intercept can be found using the formula ...

  b = y1 -m·x1

  b = 4 -(1)(-2) = 6

Then the slope-intercept equation is ...

  y = mx + b

  y = x + 6

The slope is 1; the equation is y = x+6.

Answer:

the answer is

slope:1

y=x+6

Answer: 2 numbers are 19 and 39

Step-by-step explanation:

y = x + 20

Equation: x + y  + 20 = 78

⇔ x + y = 78 - 20

⇔ x + y = 58

⇔ y = 58 - x

So, we have:

x + 20 = 58 - x ( = y)

⇔ x + x = 58 - 20

⇔ 2x = 38

⇔ x = 19

⇒ y = x + 20 = 19 + 20 = 39

But pls do.

A point that has the polar coordinate [tex](r,\theta)[/tex] can also be represented by [tex](r, \theta+2n\pi)[/tex] and [tex](-r, \theta+(2n+1)\pi)[/tex].

From the list of given options, [tex](r,\theta)[/tex] and [tex](-r, \theta+\pi)[/tex] are represents the same point

Recall that:

[tex](r, \theta+2n\pi)[/tex] and [tex](-r, \theta+(2n+1)\pi)[/tex] represents the same point

Where n is an integer

Assume [tex]n = 0[/tex]

[tex](r, \theta+2n\pi)[/tex] becomes

[tex](r, \theta+2n\pi) = (r, \theta+2\times 0 \times \pi)[/tex]

[tex](r, \theta+2n\pi) = (r, \theta+0)[/tex]

[tex](r, \theta+2n\pi) = (r, \theta)[/tex]

Similarly,

[tex](-r, \theta+(2n+1)\pi)[/tex] becomes

[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(2\times 0+1)\pi)[/tex]

[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(0+1)\pi)[/tex]

[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(1)\pi)[/tex]

[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+\pi)[/tex]

This means that: [tex](r,\theta)[/tex] and [tex](-r, \theta+\pi)[/tex] represent the same point.

Hence, (d) is correct.
