The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall. whatis the best value for x

Answers

Answer 1

Answer:

x = 62.96°

Step-by-step explanation:

From the attached figure,

Base, b = 10 ft

Hypotenuse, H = 22 ft

We need to find the value of x. We can use trigonometry to find it.

We know that,

[tex]\cos\theta=\dfrac{B}{H}[/tex]

Putting all the values,

[tex]\cos x=\dfrac{10}{22}\\\\x=62.96^{\circ}[/tex]

So, the value of x is 62.96°.

Which is the graph of y= 3/4x - 3?

Answers

The answer is Graph A.

The equation is written in slope-intercept form y=mx+b, so the slope m is 3/4, and the y-intercept is -3.

You can immediately eliminate graph B because its y-intercept is 3, not -3.

Then, you can count the rise/run for the other two graphs to see which one has a rise/run of 3/4. That’s graph A (graph C has a rise/run of 3/2, so it’s wrong).

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.

Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:

[tex]a^2=b^2+c^2-2bc*cos(A)[/tex]

In triangle IJK:

We can find the length of j using cosine rule:

[tex]j^2=k^2+i^2-2ik*cos(J)\\\\substituting:\\\\j^2=59^2+80^2-2(80)(59)cos(106)\\\\j^2=3481+6400-(-2602)\\\\j^2=3481+6400+2602\\\\j^2=12483\\\\j=\sqrt{12483} \\\\j=112\ cm[/tex]

How do I find the y-intercept of a graph? ​

Answers

Answer:

the y intercept on a graph is the line that goes up and down

Step-by-step explanation:

Step-by-step explanation:

Every point on the y-axis has 0 as its x-coordinate. The y-intercept is the point of intersection of the graph and the y-axis.

To find the y-intercept, let x = 0 in the equation of the graph and solve for y. The value of y is the y-intercept.

For example, what is the y-intercept of

2x + 3y = 6

Let x = 0.

2(0) + 3y = 6

Solve for y.

3y = 6

y = 2

The y-intercept is 2.

The solution to the system of equations is (-7, 11). true or false

What’s the X coordinate of the vertex

Answers

Step-by-step explanation:

f(x) = (x + 3)(x - 5)

In a Quadratic curve, the x-coordinate of the vertex is equidistant to the x-intercepts. (If they exist)

In f(x), our x-intercept are x = -3 and x = 5.

=> (-3 + 5)/2 = 1.

Hence the x-value of the vertex is 1.

Correct answer is x=1
