Answer 1
Since 56.76 degrees is beta, 56.76 is adjacent and x is hypothesis.
Adjacent over hypothesis is cosine. So,
Cos(56.76) = 56.76/x
X = 56.76/cos(56.76)

need help pleaseeeeeeeeeeeeee

Answers

Answer:

Step-by-step explanation:

We can calculate a few points, such as when x = 0, y = 0 (which sometimes doesn't happen), and the lowest point (where y is the smallest)

When x = 0, y = 3, so (0,3) is one of the points, and is also the y intercept

When y = 0, x = -3, and it also happens that 0 is the lowest point that y can be, since no value of x would make y negative.

Now, we have two points, (0,3) and (-3,0)

Graph B is the one one which has both the points (0,3) and (-3,0) on it, and indeed, y never reaches below the x axis since y can't be negative

If a snowball melts so that its surface area decreases at a rate of 1 cm2/min, find the rate at which the diameter decreases when the diameter is 12 cm. (Give your answer correct to 4 decimal places.) cm/min

Answers

The rate at which the diameter decreases is 0.0159cm/min.

Given that a snowball melts and its surface area decreases at a rate of 1cm²/min.

The surface area of a solid object may be a measure of the entire area that the surface of the thing occupies.

The surface area of the snowball is A=4πr² because the snowball is spherical.

Here, r is the radius of the snowball.

Let D be the diameter of the snowball.

As the radius is half of the diameter

The surface area of a snowball can also be rewritten as

A=4π(D÷2)²

A=4π(D²÷4)

A=πD²

Given that the surface area decreases by 1cm²/min, so,

dA÷dt=-1cm²/min.

Differentiating both sides in A=πD² and get

dA÷dt=2πD(dD÷dt)

Given that the diameter is 12cm.

Substitute these values in the formula and find dD÷dt

-1=2π×12×(dD÷dt)

-1=24π×(dD÷dt)

-1÷24π=dD÷dt

-0.0159≈dD÷dt

Hence, the diameter decreases at the rate of 0.0159 cm/min when the diameter is 12 cm.

Triangle JKL is transformed to create triangle J'K'L'. It can be a rigid or a non rigid transformation depending on whether the corresponding side lengths have the same measures.

What is a transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the increase or decrease in the size of a figure.

A rigid transformation such as reflection, rotation and translation preserve the shape and size, hence the pre-image and image have the same corresponding angle and side measures.

A non rigid transformation such as dilation preserve the shape and not size, hence the pre-image and image have the same corresponding angle measures.

Answers

Answer:

m = 2/3

Step-by-step explanation:

Rewrite in slope-intercept form.

y = -3/2x + 7/2

Using the slope-intercept form, the slope is −3/2.

m = -3/2

The equation of a perpendicular line to y=−3/2x + 7/2 must have a slope that is the negative reciprocal of the original slope.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

• First rewrite the original equation in the form y = mx + c ,

where m = gradient:

[tex]3x + 2y = 7[/tex]

⇒ [tex]2y = -3x + 7[/tex]

⇒ [tex]y = \frac{-3}{2}x + \frac{7}{2}[/tex]

• From this equation, we can see that the gradient, m = [tex]\frac{-3}{2}[/tex] .

The gradient of a line perpendicular to another line with gradient m,  = [tex]\frac{-1}{m}[/tex].

∴ gradient of perpendicular = -1  ÷   [tex]\frac{-3}{2}[/tex]

What is an equation for the line parallel to y = −x + 2 going through the point (−3, −5)?

Answers

The equation for the line parallel to y = −x + 2 going through the point (−3, −5) is y = -x - 8

Equation of a line

The equation of a line in point slope form is expressed as:

Given the equation y = -x + 2, the slope of the line parallel to the line is -1

Substitute the slope and point (-3, -5)

y -(-5) = -1(x - (-3))

y+5 = -(x + 3)

y+5 =-x - 3

y = -x - 3 - 5
