Answer:

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:

[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)

Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.

Then, we clear the variable within (1):

[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]

[tex]x = 13.233\,cm[/tex]

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

Answer:

y = 3 cm and x = 2.5 cm

Step-by-step explanation:

As we can see it is a parallelogram so

y = 3 cm (being opposite sides of parallelogram)

Now while calculating the diagonal we can use the Pythagoras relation. i.e

perpendicular (p) = 4 cm (IH)

Base (b) = 3 cm (FI)

Hypotenuse (h) = FH = ?

We know by using Pythagoras theorem

h = √ p² + b²

= √ 4² + 3²

= √ 25

= 5 cm

Here we got FH = 5 cm

so the value of x will be 2.5 cm as the diagonal bisects.

Hope it will help :)

Answer:

(2x+2y+7)(x+y+7)

Step-by-step explanation:

I suspect this is what you are expected to do.

Define z=x+y

2z^2+9z+7

2z^2+2z+7z+7

2z(z+1)+7(z+1)

(2z+7)(z+1)

(2x+2y+7)(x+y+7)

Step-by-step explanation:

6x-8y=12

5x+8y=-1

add them

11x=11

x=1

y=-3/4

Answer:

(1,-3/4)

Step-by-step explanation:

Luckily, y is already opposites, so it should be easier:

6x-8y=12

5x+8y=-1    

Combine; This should end up with y eliminated -

11x = 11

x = 1

Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.

5(1) +8y = -1

5+8y=-1

8y=-6

y=-6/8 (you can simplify)

The point at which the lines intersect is (1,-3/4)

Answer:

b = 34

m = 5

f(t) = 5x+34

Step-by-step explanation:

f(0) = 34, so that is its y intercept.

f(t) contains (0,34) and (8,74), which can be used to find the slope:

Answer:

(f o g)(x) = 4x^2 - 8

Step-by-step explanation:

(f o g)(x) = f(g(x))

f(x) = x^2 - 8

g(x) = 2x

f(g(x))

f(2x) = (2x)^2 - 8

       = 4x^2 - 8

(f o g)(x) = 4x^2 - 8

Answer:

70 kilometers

Step-by-step explanation:

Set up a proportion where x is the actual distance

[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]

Cross multiply:

x = (20)(3.5)

x = 70

So, the actual distance is 70 km

Answer:

Day 1=15 Day 2=30 Day 3=45 Day 4= 60 Day 5= 75. The expression is N+15

Step-by-step explanation:

The complete table:

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of bacteria samples analyze each day = 15

The equation for the number of bacteria analyzes after x days.

B = 15x

Now,

x = 1, B = 15

x = 2, B = 30

x = 3, B = 45

x = 4, B = 60

x = 5, B = 75

Thus,

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

#SPJ5

The circumference is 615.44.

The formula is

R = C/(pi)*2

( 2 is square)

( I can't find the pi symbol sorry)

So meaning  in simple term, it would look like this

R = 615.44/2*(3.14)

615.44/6.28

then we divide which we will get 98

Answer: Subtract the equations in system A.

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

Explanation:

The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.

There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.

For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y

So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.

Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.

Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.
