What is the length of BC in the right triangle below?

Answer:

56

Step-by-step explanation:

The 3 part of the ratio represents daisies.

Divide the number of daisies by 3 to find the value of one part of the ratio.

42 ÷ 3 = 14 ← value of 1 part of the ratio, thus

4 parts = 4 × 14 = 56 ← number of roses

Explanation:

Length of transverse axis of hyperbola means distance between both the vertices of hyperbola which is constant given by 2a.

As definition of hyperbola:

Difference in distance of any point (x,y) from both focus is a positive constant equals to length of transverse axis.

So, distance of (x,y) from foci 1)-( distance of (x,y) from foci 2)=2a

x-y=2a

Length of transverse axis is x-y.

Good luck on your assignment

The length of the transverse axis is x - y if point (x, y) is separated from either focus by a positive constant equal to the transverse axis' length option (C) x - y is correct.

It's a two-dimensional geometry curve with two components that are both symmetric. In other words, the number of points in two-dimensional geometry that have a constant difference between them and two fixed points in the plane can be defined.

We have given a hyperbola shown in the picture.

The green line indicates the transverse axis of the hyperbola.

As we know,

The distance between the two vertices of the hyperbola, which is always given by 2a, is referred to as the length of the transverse axis.

Any point (x, y) is separated from either focus by a positive constant equal to the transverse axis' length.

x-y=2a

The length of the transverse axis =  x - y

Thus, the length of the transverse axis is x - y if point (x, y) is separated from either focus by a positive constant equal to the transverse axis' length option (C) x - y is correct.

Problem 5:

Since parallelogram ABCD has to be a parallelogram, than that means that all opposite sides have to be congruent on it. One side has to be equivalent to the opposite side, so the equation on that line is equivalent to the equation on the opposite side, as well. EXAMPLE: 5x = 3x+10, which turns to 2x = 10, which turns to x = 5.

Problem 6:

Just like Problem 5, the opposite lines in the middle of the rhombus have to be congruent to one another since the given shape must be a parallelogram. So 4x = 8, and that turns to x = 2. I solved all of these problems using multi-step equations.

Answer: B

Step-by-step explanation:

Given that the scatter plot with points going down from about zero comma 4 to the right to about 7 comma zero. That is, (0 , 4 ) to ( 7, 0 )

Let's first find the slope M

M = (0 - 4)/( 7 - 0)

M = - 4/7

Since the line of best fit is linear, let adopt general equation of straight line

Y = MX + C

As the line passes through ( 0 , 4 )

Substitutes for Y and X

4 = - 4/7 (0) + C

C = 4

Where C = intercept

The equation for the line of best fit to represent the data will be:

Y = - 4/7 X + 4

Y equals negative two thirds times x plus 4

Answer:

It is non function

Step-by-step explanation:

because the x values repeated, the input ( x values) produce more than one output.

This is not a function because for a value of x the value of the y comes out to be two.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The set of ordered pairs are as given below.

{(19,15),(−25,0),(−16,11),(−2,12),(−16,14),(−13,20)}

The relation to be a function for each value of the x the value of the y should be unique.

This is not a function because for a value of x the value of the y comes out to be two.

Answer:

2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it

1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.

We are given the three expressions different from each other

We are supposed to find  what may be same or different.

1) [tex](-2)^2[/tex]

1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.

Answer:

Option (1). h = -2

Step-by-step explanation:

This question is incomplete: here is the complete question.

The graph shows the function f(x) = [tex](2.5)^{x}[/tex] was horizontally shifted by a value of h to get the function g(x) = [tex](2.5)^{x-h}[/tex]. What is the value of h ?

From the graph attached,

Point (0, 1) lies on function f(x).

If the graph of function f(x) is shifted h units left horizontally, rule for the translation will be,

f(x + h) → g(x)

For 2 units shift to the left horizontally,

f(x + 2) → g(x)

[tex](2.5)^{x+2}[/tex] = [tex](2.5)^{x-h}[/tex]

By comparing both the sides,

x + 2 = x - h

h = -2

Therefore, Option (1) will be the answer.

Answer:

0.49

Step-by-step explanation:

0.7^2 is the same as 0.7*0.7.  You just have to times them together!

Hope this helps!

The solution is z^2= 0.49.

A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

For example, 4 and −4 are square roots of 16, because 4² = ² = 16.

here, we have.

z^2=z*z

when z = 0.7

z^2= 0.7*0.7

     =0.49

0.7^2 is the same as 0.7*0.7.

Hence, the solution is z^2= 0.49.

Answer:

Base = 35 inch

Step-by-step explanation:

Given that the triangle is an isosceles triangle;

The length of the two sides is: 12b - 8

The length of the base is: 9b + 8

Perimeter = 91 inches

Required

Calculate the length of the base;

The perimeter of a triangle is gotten by adding the length of the three sides.

So, in this case; we have

[tex]Perimeter = 12b - 8 + 12b - 8 + 9b + 8[/tex]

Collect like terms

[tex]Perimeter = 12b + 12b + 9b - 8 - 8 + 8[/tex]

[tex]Perimeter = 33b - 8[/tex]

Substitute 91 for Perimeter

[tex]91 = 33b - 8[/tex]

Add 8 to both sides

[tex]91 + 8 = 33b - 8 + 8[/tex]

[tex]99 = 33b[/tex]

Divide both sides by 33

[tex]\frac{99}{33} = \frac{33b}{33}[/tex]

[tex]3 = b[/tex]

[tex]b = 3[/tex]

Recall that the base of the triangle is 9b + 8

Base = 9b + 8

Substitute 3 for b

Base = 9(3) + 8

Base = 27 + 8

Base = 35 inch

Answer:

2) 5 to 10

Step-by-step explanation:

The slowest average rate change will occur when, as time progresses, the height of the helicopter changes very little.

Analyzing the intervals:

In the interval from 0 to 5, the height of the helicopter, according to the graph, changes drastically.

In the interval from 5 to 10 the height hardly changes.

In the interval from 10 to 15 the height changes more than in the previous interval (downward).

And in the interval from 15 to 10 something similar the the previous interval happens, but upwards.

thus, the interval that has the smallest average rate of change is 5 to 10 since there is not much change in the height over this interval of time (compared to the other intervals).
