Step-by-step explanation:

Answer 2

Answer:

Diagonals of a parallelogram bisect each other

Given vertices:

(-2,-1), (1,3), (6,3), (3,-1)

Plot the points.

We see the diagonals are:

(-2,-1) (6,3) and (1,3), (3,-1)

The midpoint of any diagonal is the intersection of the diagonals.

Use midpoint formula to find the coordinates:

x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1

The point is (2, 1)

The product of (1.3 x 10⁻²) and (0.05) is 0.065x 10⁻²

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

We need to find the product of (1.3 x 10⁻²) and (0.05)

Multiplication is a method of finding the product of two or more numbers

First multiply as if there is no decimal.

Next, count the number of digits after the decimal in each factor.

Finally, put the same number of digits behind the decimal in the product.

1.3×0.05=0.065

So 0.065x 10⁻² is the value of product (1.3 x 10⁻²) and (0.05)

Hence, the product of (1.3 x 10⁻²) and (0.05) is 0.065x 10⁻²

The lines graphed below are perpendicular. The slope of the red line is 4.
What is the slope of the green line?

Answers

Answer: -1/4

Step-by-step explanation:

so lets just eliminate some of the choices here.

4 and -4 are 4/1 or -4/-1 and it doesnt go up or down 4 here so those can be ruled out. If we look at which way the green line is facing, positive goes up on the graph, but green line is going down so we can rule out 1/4. So all that is left is -1/4, so there's your slope.

b. -1/4 you can see two points (0,2) and (4,1) you can do rise over run or y2-y1/x2-x1 2-1/0-4= -1/4

find the missing side. round to the nearest tenth.

Answers

Answer:

A. 5.2

Step-by-step explanation:

I was taught how to do this using the SOH CAH TOA method.

Step 1: Circle your given angle.

Step 2: Label O, H, and A. The line across from your circled angle will be labeled O. The side across from the right angle is H. The last unmarked side is A.

Step 3: Cross off the useless side, in this case, that would be A because there is no corresponding information.

Step 4: Identify if it is sine, cosine, or tangent using SOH CAH TOA. In this case, you only have an O and H so we will use SOH.

Step 5: Set up the equation. The equation is [tex]\frac{sine(31)}{1} =\frac{x}{10}[/tex]. We will use sine of the given angle is equal to the side marked O over the side marked H.

Step 6: Solve for x until x is by itself, then enter into your calculator.

You will enter [tex]sine(31) * 10[/tex] into your calculator and round if necessary.

if f (x) = 8 (5x - 2) find f (x)

Answers

Answer:

f-1(x) = (x - 16)/40

Step-by-step explanation:

Call f(x) = y

Interchange x and y

x = (5y + 2)*8 Remove the brackets

x = 40y + 16 Subtract 16 from both sides

x - 16 = 40y Interchange the left and right sides

40y = x - 16 Divide by 40

y = (x - 16)/40

f-1(x) = (x - 16)/40

the width of a rectangle is 8 feet and the diagnal length of the rectangle is 13 feet which measurement is closest to the length of this rectangle in feet

Answers

Answer:

Well the whole answer is 10.246950 smth smth but I don’t have the multiple choices so your gonna have to round yourself

Step-by-step explanation:

Okay so you have a weigh of 8 and a diagonal of 13.

If you look, theres a triangle there. One side has 8 and the diagonal that was cut forms a 13. So we have a leg and a hypotnuse. To find the other leg (length) just follow the Pythagorean theroum and solve for b or a.

Pythagorean theroum: a^2+b^2=c^2

Now subsitute c for 13 since its the hypotnuse and a or b as 8 but only one.

In this case I’m substituting a for 8.

8^2+b^2=13^2

Solve the squares

64+b^2= 169

Isolate the b

b^2=105

Now square root 105

√105 will give the answer above on a normal calculator but if you have to round, I don’t know what place but you can round.

Step-by-step explanation:

Ok here is how you do it so the formula for a trapezoid is base 1 plus base 2 divided by 2 times the height. so, in this case the two bases are 2 in and 6 in so we add those together and get 8 then, we divided 8 by 2 and we get 4.

Then now, we multiply 4 and 5 for our height and get 20 inches.

What are right triangles?

A right triangle is a triangle that has one of its angle measure to be 90 degrees.

From the question, we have:

Angle B = 45 degrees

Since angle B is 45 degrees, then the legs of the triangle are equal (i.e. 12 cm)

Hence, the measures of the lengths and angles are: BC = 12cm, <B = 45, AC = 12cm
