what is the equation of the line that passes through the point (−1,1)(−1,1) and has a slope of 5?

The value of the variable , k is -385/13

A function can be described an expression, equation, law or rule explaining the relationship between two variables.

These variables are known as;

From the information given, we have the function;

f(x)=-(13)/(5)x+k

Also, for the value of f(30), the function is equivalent to -1

Now, substitute the value of x as 30 and equate the function to -1. we have;

-1 = -13/(5)30 + k

Divide both sides by the cofficient of 30 + k

30 + k = -1 × -5/13

Multiply the values

30 + k = 5/13

Now, collect like terms

k = 5/13 - 30

k = -385 /13

Thus, the value is -385/13

It's a fact that the sum of the angles of a triangle add up to 180º.

So, 55º + 85º + (3x+4)º = 180º.

That's the equation you need to solve:

     55 + 85 + 3x+4 = 180    (combine like terms)

                 144 + 3x = 180   (subtract 144 from both sides)

                           3x = 36     (divide both sides by 3)

Length of side of the rhombus is 5cm.

A rhombus can be thought of as a special parallelogram since it satisfies the requirements for one (a quadrilateral with two pairs of parallel sides). Another characteristic of a rhombus is that it has four equal sides, just like a square. It is also known as a tilted square for this reason.

step1

Diagonals of a rhombus bisect each other at right angles.

Let point of intersection of diagonals be O

So, OD = 3cm , OA = 4cm

From Right angled triangle △ AOD,

⇒ AD²  = OA²  + OD²   (Pythagoras theorem)

⇒ AD² =4² + 3²

⇒ AD² = 16+9

⇒AD² =25

step2

⇒ AD² =25

⇒ AD=5 cm

AD is side of the rhombus.

So, length of side of the rhombus is 5cm

Step-by-step explanation:

The estimated age of the tomb of Sneferu is 8,330 years.

The age of the tomb can be estimated using the carbon-14 decay equation, which states that the amount of carbon-14 remaining after time t (in years) is equal to the initial amount of carbon-14 multiplied by 0.5^(t/5730).The decay equation for carbon-14 is A = A₀e⁻kt, where A₀ is the original amount of carbon-14, A is the amount of carbon-14 at time t, k is the decay constant, and t is the amount of time that has passed.

We can rearrange the equation to solve for t: t = -ln(A/A₀)/k. In this equation, A is the amount of carbon-14 found in the cypress beam, and A₀ is the amount of carbon-14 found in living cypress wood.

In this case, the initial amount of carbon-14 was 100%, and the remaining amount was 55%. Solving for t, we get t = (ln(55%)/ln(0.5))*5730 = 8,330 years.

Therefore, the estimated age of the tomb of Sneferu is 8,330 years.

Answer:

let say the 3 points that make the triangle is A-B-C, you draw a line from A to the line opposite to A, make it perpendicular. If it's not inside of the triangle, you just extend the line to make it work.  Then repeat for B and C.  Then you extend the perpendicular lines (altitude) and make them intersect.  The intersect point is the orthocenter.

Step-by-step explanation:

Then you extend the perpendicular lines (altitude) and make them intersect.  The intersect point is the orthocenter.

Answer:

  see attached

Step-by-step explanation:

You want to construct the orthocenter of the given triangle.

The orthocenter of a triangle is the point of intersection of the altitudes. The construction of it requires construction of at least two altitudes of the triangle. This is accomplished using the "perpendicular through an external point" construction.

A perpendicular to a line through a point not on the line is constructed in a few simple steps:

The attachment shows arc FG using C as a center, and arc HI using A as a center. Arcs using those points as center are drawn so they intersect at points V and W.

Lines CV and AW are altitude lines that intersect at the orthocenter: point Z.

Additional comment

The vertices of the original triangle have been labeled A, B, C counterclockwise from upper left.

It may appear that point Z is a reflection of point C in line AB, but it is not.

a) The circumference of the tire is 7.85 ft

b) About 673 times the tire will have to rotate to travel 1 mile.

The diameter of a tire is 2. 5 ft.

Let r represents the radius of the tire.

r = diameter/2

r = 2.5 / 2

r = 1.25 ft

a)  the circumference of the tire:

We know that the formula for the circumference of circle:

C = 2πr

So, the circumference of the tire would be,

C = 2 × π × r

C =  2 × π × 1.25

C = 7.85 ft

b) Let the tire will have to rotate n times in order to travel 1 mile.

We know that 1 mile = 5,280 ft

So, n = 5280 / 7.85

n = 672.6

Let L represent the number of Large boxes.

Let S represent the number of Small boxes.

Total number of boxes = 120

L + S = 120

The two equations are:

L + S = 120

55×L + 15×S = 3800

L + S = 120 eliminate L by multiplying this equation by -55

-55×(L + S = 120)      

The equations are:

55 ×L + ×15S = 3800

-55×L -55×S = -6600

0 - 40×S = - 2800

S = -2800/(-40)

S = 70

Plug S back into one of our equations.

L + S = 120

L + (70) = 120

L = 120 - 70

If one addend of x is c, the other addend is x-c.

An addend is a term that is added to another term to form a sum. In the equation x = c + (x-c) , c and (x-c) are the two addends that make up the sum x.

The reason why x-c is the other addend is that the sum of the two addends (c and x-c) must equal x.

In other words x = c + (x-c) can be simplified to x = c + x - c which is x = x

Answer:

a) The two side lengths of the tenth rectangle in the sequence are 8 + (10 - 1)4 = 32 and 8 + (10 - 2)4 = 28.

b) The area of 576in2 is not possible in the given sequence because it would require a side length of 24, which does not follow the sequence given.

Step-by-step explanation:

The given sequence is represented by the equation an=8+(n−1)4, which means that for each successive rectangle in the sequence, the length of one of the sides will increase by 4. Therefore, in order for the area of a rectangle to be 576in2, the length of one of the sides must be 24, which does not follow the sequence given.

If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), the derivative of cross product d/dt [u (t) x v (t)] is (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t)).

Formula 5 of the cross product theorem states that the derivative of the cross product of two vectors u and v is equal to the cross product of the derivatives of u and v:

d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt)

Where u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), we can find the derivatives as follows:

du/dt = (d(sin 3t)/dt, d(cos 3t)/dt, dt/dt)

= (3 cos 3t, -3 sin 3t, 1)

dv/dt = (dt/dt, d( cos 3t) /dt, d( sin 3t)/dt)

= (1, -3 sin 3t, 3 cos 3t)

Now, we can substitute these derivatives into the formula to find d/dt [u (t) x v (t)]:

d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt) = (3 cos 3t, -3 sin 3t, 1) x (t, cos 3t, sin 3t) + (sin 3t, cos 3t, t) x (1, -3 sin 3t, 3 cos 3t)

= (-3sin²3t - cos3t, t - 3cos3tsin3t, 3cos²3t + 3tsin3t) + (3cos²3t + 3tsin3t, t - 3cos3tsin3t, -3sin²3t - cos3t)

= (3cos²3t + 3tsin3t - 3sin²3t - cos3t, 2t - 6cos3tsin3t, 3cos²3t + 3tsin3t - 3sin²3t - cos3t)

= (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t))

Here we know that the amount of sand left in a 600 mL vase can be modeled by the equation that is written as,

=> s = – 1/5 t + 600

here s refers the amount of sand left in the vase and t refers time in minutes since the sand started leaking out

Here we also know that the vase is full of sand and sand leaks out of the vase until the vase is empty.

Then in order to find the domain we have to put the value of s as 0, then we get the domain as,

=> 0 = -1/5t + 600

=>1/5t = 600

=> t = 3000

Then the domain is [0, 3000].

Similarly, in order to find the value of range we have to put the value of t as zero, then we get
