Solve this equation please :)

The x-intercept would be 5.6, and the y intercept would be 4, if that helps.

Answer:

Step-by-step explanation:

You are sorta on the right track, but .... ∠3+81°+∠4 =180°

along with 88°+∠1=180°

∠1-92°

I know why  you put 88° for ∠2 but , it's only 88° from a line parallel to that top line,  not the hypotenuse of the triangle.  But good idea, just not able to apply that here.  

you've nicely marked the two parallel lines so we know that ∠3 will math the other 64° angle ,  now you can solve for ∠2

∠1=92° and ∠3=64°  so ∠2 must equal 180-92-64=24°

∠2=24°

now solve for ∠4

180-64-81=∠4

∠4=35°

finally we can get ∠5

180-35-64=∠5

∠5=81°

and , we should have also seen that ∠5 would be the same as the 81° angle above it by ∠3 and ∠4  since those lines are parallel.

Hope that helps :)

To reach the break-even point, the publisher should sell 40,000 books.

A break-even point (BEP) is the point where revenues = total cost. Hence, at this point, the company does not gain profit or loss.

On the other hand, total cost is calculated as:

Total cost = fixed cost + variable cost

Where variable cost depends on the number of units produced.

Therefore,

Total cost = fixed cost + number of unit produced x cost per unit

Parameters given in the problem:

fixed cost = h. 400,000

unit cost = h. 35

selling price = h.45 per unit

Let p be the number of books sold. Then,

Revenues = 45 x p

Total cost = 400,000 + 35 x p

At break-even point:

Revenues = total cost

45 x p = 400,000 + 35 x p

10 p = 400,000

p = 40,000

Hence, the break-even point is 40,000 books

The non-real solutions according to the equation is (1 + √5 i)/3 and (1 - √5 i)/3.

A polynomial can be factored, and its roots can be discovered using the factor theorem. The polynomial residual theorem is indeed a special instance of this one.

A polynomial f(x) has a factor (x-a), as was noted in the beginning, if and only if f(a) = 0.

As per the given equation in the question,

3x⁵ + 25x⁴ + 26x³ - 86x² + 76x - 48

The function can be written as:

f(x) = g(x).h(x)  (i)

The real solutions from the graph is,

x₁ = -6, x₂ = -4 and x₃ = 1.

So,

g(x) = (x + 6) × (x + 4) × (x - 1)

g(x) = (x² + 10x + 24) × (x - 1)

g(x) = x³ + 9x² + 14x - 24.

Now, substitute the values in (i)

3x⁵ + 25x⁴ + 26x³ - 86x² + 76x - 48 = (x³ + 9x² + 14x - 24) × (ax² + bx + c)

Therefore,

ax⁵ = 3⁵

a = 3.

-24c = -48  

c = 2.

-24(bx) + 14(cx) = 76x

-24b + 28 = 76

b = -2.

The equation for non-real solution:

h(x) = 3x² - 2x + 2.

Δ = b² - 4ac = (-2)² - 4(3)(2) = -20

x₁ = (2 + √20)/6 = (1 + √5 i)/3

x₂ = (2 - √20)/6 =  (1 - √5 i)/3

Answer:

16(x+5)

Step-by-step explanation:

16x+80

=8(2x+10)

=16(x+5)

The algebraic factor of the given expression 16x + 80 will be 16(x + 5).

An algebraic factor is the multiplication of two algebraic terms.

That term could be in form of summation multiplication or in subtraction.

The root of the quadratic equation formed by the algebraic factor is always real.

As per the given expression,

⇒ 16x+80

Take 8 as common

⇒ 8(2x + 10)

Take 2 as common

⇒ 8 × 2 (x + 5)

⇒ 16 (x + 5)

Q36 this is geometry if anyones good at it can someone help me pls

Answer:

mAngleT = 60°

mAngleU = 60°

TS = 13cm

SU = 13cm

Step-by-step explanation:

Since two of the sides are the same the two base angles are also the same. One is 60° so the other one is 60° also. But if they are both 60° and all the angles add up to 180° the last one has to be 60° also.

One side is marked 13cm. It is marked congruent to the left side so they are both 13cm.

But we saw from the angles all being the same, that this is actually an equilateral triangle. So all three sides are the same.

The sum of the interior angles of a 17-sided polygon is 2700 °.

Given:

sum of the interior angles of a 17-sided polygon.

we know that:

sum of interior angles = n-2 * 180

n = 17

= (17-2)*180

= 15*180

= 2700 °

Therefore the sum of the interior angles of a 17-sided polygon is 2700 °.

then 100000 x 30 = 3000000

and there is 6 zeros

Answer:

1. 95=8x+55  8x=40  x=5  Reason: Since m and n are parallel, and a line traverse through it, they are corresponding angles, meaning that their angle is the same.

2. 200-2x=130  200-130=2x  2x=70  x=35  Reason: The two angles are the same because the "130-degree" angle's corresponding angle is the vertical angle of the "200-2x" angle.

3. Yes, we can use the corresponding angle theorem to prove that m and n are parallel.

4. No, there's not enough information to determine because both given angles are on line m, we need an angle on line n as well.

5. No, the same explanation as 4^^^ Vertical angles do not necessarily prove that two lines are parallel.

6. Yes, we can use the corresponding angles theorem, and then use the vertical angles theorem.

In statistics, a confidence interval defines the possibility that a population parameter will fall between a set of values for a certain proportion of the time. Analysts commonly incorporate confidence zones that encompass 95% or 99% of the expected data. Thus, if a point estimate of 10.00 is derived using a statistical model with a 95% confidence interval of 9.50 - 10.50, there is a 95% chance that the real value falls within that range.

What is the need for Confidence Intervals?

Confidence intervals are one technique to illustrate how "accurate" an estimate is; the higher the 90% confidence interval for a certain estimate, the more the precaution advised when employing the estimate. Confidence intervals serve as a crucial reminder of the estimates' limitations.

The graph of the quadratic function x² + 3x - 108 is given by the image shown at the end of the answer.

Three features have to be considered to obtain the graph of a quadratic function.

The function for this problem is defined as follows:

a = 1, b = 3, c = -108.

Hence the coefficients of the function are given by:

a = 1, b = 3, c = -108.

Inserting these points into a calculator, the x-intercepts of the function are:

Hence the function crosses the x-axis at x = -12 and at x = 9, and it is a concave up parabola, as the coefficient a is positive.

The y-intercept of the function is given as follows:

f(0) = 0² + 3(0) - 108 = -108.

Hence the graph crosses the y-axis at y = -108.

The axis of symmetry of the function is:

x = -b/2a = -3/2 = -1.5.

The y-coordinate of the vertex is:

f(-1.5) = (-1.5)² + 3(-1.5) - 108 = -110.25.

Step-by-step explanation:

The cost of materials for the least expensive such container is 245.31 dollars .

Suppose the width of container is x (m),

length of the base of container is 2x (m)

the base area of container is (length × width)sq. m i.e 2x² meter².

Since the volume of container is 10 m³.

the height of container = area of container/ volume of container

height of container= 10/2x² m = 5/x² m

The cost of making such container is cost of base = 2x²*10 = 20x².

cost of sides of container = (2×2x × 5/x² + 2× x × 5/x²)×6 = 180/x

The overall cost is hence the sum of the base and the sides: f(x) = 20x² + 180/x

The get the minimum,

df(x)/dx = 20×(2x - 9/x²) = 0

so 2x = 9/x^2 => 2x = 2.0800 ==> x = 1.651 m
