help me please ? i need help with this table

Here

cos25°=BC/AB=8/c

c=8/cos25°

so cos function is helpful here

really a dum.beannie

Answer:

b) cos25

c = 7.248 or 7.2

Step-by-step explanation:

Cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]

Cos 25 = [tex]\frac{8}{c}[/tex]

Cos of 25 is 0.906

0.906 = [tex]\frac{8}{c}[/tex]

Multiply 8 on both sides:

0.906 x 8 = [tex]\frac{8}{c}[/tex] x 8

7.248 = c

Answer:

c

Answer:

AB and CD - Parallel Lines

EF and CD - Perpendicular Lines

GH and EF - Neither Parallel nor Perpendicular Lines

Let me know if this helps!

Answer:

EF and CD ------- perpendicular lines

AB and CD --------parallel Lines

GH and EF --------- neither parallel nor perpendicular lines

Step-by-step explanation:

Parallel lines are lines that do not ever intersect

Perpendicular lines create 90 degree angles

neither is just neither

Answer:

15

Step-by-step explanation:

Here,

x= -7

f(x)= -x+11-3

f(-7)= -(-7)+11-3

     =7+11-3

     =18-3

     =15

Answer:

y = 1.5, x = [tex]1\frac{12}{13}[/tex]

Step-by-step explanation:

The given simultaneous equation system is;

-1 - 2·y = -4...(1)

13·x + 2·y = 28...(2)

By elimination method, we have;

From equation (1);

-1 - 2·y = -4

2·y = 4 - 1 = 3

y = 3/2 = 1.5

y = 1.5

We eliminate 'y' from equation (2) by replacing the value of 'y' with 1.5 as follows;

13·x + 2·y = 28

y = 1.5

∴ 13·x + 2 × 1.5 = 28

13·x = 28 - 3 = 25

x = 25/13 = [tex]1\frac{12}{13}[/tex] = [tex]1.\overline{923076}[/tex]

x = [tex]1\frac{12}{13}[/tex]

Answer:

20 times greater

Step-by-step explanation:

Given the following

Population of alaska = 6.5 * 10^(5) people

Population of illinois's = 1.3 * 10^(7)people.

To know the number of times population of Illinois in the population of Alaska, we will take their population ratio;

Ratio = Population of illinois's /Population of alaska

Ratio = 1.3 * 10^(7)/6.5 * 10^(5)

Ratio = 0.2 * 10^7-5

Ratio = 0.2 * 10^2

Ratio = 20

Hence the population of Illinois is 20 times greater than population of alaska

Given

The probability that Miriam will spin on her next turn is [tex]\frac{1}{4}[/tex]

That; is there are chances that she can produce 4 on her spin but it not certain that she will produce this result.

Likely word aptly describes the situation while impossible negates the chances of that outcome.

Answer:

1/2p=24

p=48

19+t=23

t=4

Step-by-step explanation:

first one

multiply both sides by two. and then there is your answer. it will get rid of the denominator.

second one.

subract 19. isolates the variable.

Answer:

B) 15p < 60  (Cant put line under <, sorry)

Step-by-step explanation:

He cant spend more than what he has, but he can spend less than or equal to it. This equation is correct, because you want to multiply your shirts, p, by how much they are, 15.  I hope this helps :)

Answer:

it's B he cant spend more the 60 dollars but each polo shirt cost $15 so that would mean it would be

$15 for each shirt so

15p has to be less then or equal to 60

Answer:

Side = 0.7 units

Step-by-step explanation:

Area of a square = 0.49 sq. units

Side² = 0.49

side² = [tex]\frac{49}{100}\\\\[/tex]

[tex]side = \sqrt{\frac{49}{100}}=\sqrt{\frac{7*7}{10*10}}\\\\sides=\frac{7}{10}=0.7[/tex]

Answer:

[tex]Rate = -5[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x^2 - x - 4[/tex]

[tex]-4 \le x \le 2[/tex]

Required

Determine the average slope over the given interval

This is calculated as:

[tex]Rate= \frac{f(b) - f(a)}{b - a}[/tex]

Where:

[tex]a = -4[/tex]

[tex]b =2[/tex]

So:

[tex]Rate= \frac{f(2) - f(-4)}{2 - (-4)}[/tex]

[tex]Rate= \frac{f(2) - f(-4)}{2 +4}[/tex]

[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]

Solving for f(2) and f(-4), we have:

[tex]f(x) = 2x^2 - x - 4[/tex]

[tex]f(2) = 2 *2^2 -2 - 4[/tex]

[tex]f(2) = 2[/tex]

[tex]f(-4) = 2*(-4)^2 - (-4) - 4[/tex]

[tex]f(-4) = 2*16 +4 - 4[/tex]

[tex]f(-4) = 32[/tex]

So, the equation becomes

[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]

[tex]Rate= \frac{2 - 32}{6}[/tex]

[tex]Rate= \frac{-30}{6}[/tex]

[tex]Rate = -5[/tex]

Answer: The new co-ordinates of A ( 2 ,-6)

Step-by-step explanation:

Type of transformation                                change to co-ordinate point

Vertical translation up 'd' units                  (x,y)→(x , y+d)

Vertical translation down 'd' units             (x,y)→(x , y-d)

Horizontal translation right 'c' units           (x,y)→(x+c , y)

Horizontal translation left 'c' units           (x,y)→(x-c , y)

Reflection over x-axis                               (x,y) →(x , -y)

Reflection over y-axis                               (x,y) →(-x , y)

Given the original vertex A ( -2 ,3)

a) First reflection over x-axis  ( -2 ,3) →(-2 , -3)

b) Vertical translation down '3' units  so it changes (-2 , -3)→(-2 , -3-3)

                        (-2,-3)→(-2 ,-6)

and

c) The Horizontal translation right '4' units

now it changes ( -2 ,-6) → (-2+4,-6)→(2 ,-6)

Final answer:-

The new co-ordinates of A ( 2 ,-6)

Answer:

45158

Step-by-step explanation:

Since the colony grows at a rate of 12%, after 2 years there will be [tex]36000\cdot 1.12^2 = 45158.4[/tex] bacteria. Since you probably can't have part of a bacteria, you round to 45158.

Answer:

45158

Step-by-step explanation:

Since the colony grows at a rate of 12°/• , after 2 years there will be 36000.

1.12 power of 2 = 45158.4 bacteria.

And you cant have part of a bacteria

you round it to

45158.
