The vertex angle of the isosceles triangle is 22°.

What is isosceles triangle?

A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.

We know that an isosceles triangle is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180degrees.

Base angle = 3vertex angle+13.

=> 2base angle + vertex angle = 180°

=> 2(3 vertex angle +13)+vertex angle = 180°

=> 6 vertex angle+26+vertex angle = 180

=> 7 vertex angle = 180-26

=> 7 vertex angle = 154

=> vertex angle = 154/7 = 22°.

Hence the vertex angle of the isosceles triangle is 22°.

About 80 necklaces have more than 28 beads. Then the correct option is C.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and the standard deviation is 4 beads.

P(x > 28) = P(x - 24 / 4 > 28 - 24 / 4)

P(x > 28) = P(x - 24 / 4 > 1)

P(x > 28) = 1 - ∅1

P(x > 28) = 1 - 0.8413

P(x > 28) = 0.1587

Multiply both sides by 500, then we have

500 P(x > 28) = 0.1587 × 500

500 P(x > 28) = 79.35

500 P(x > 28) ≈ 80

Answer:

The amount invested at 8% is 64,500-32,000 = 32,500

Step-by-step explanation:

one investment: 3%, amount: x

the other: 8%, amount: 64,500-x because x is invested at 3%

0.03x+0.08(64,500-x) = 3,560

0.03x+5,160-0.08x = 3,560

-0.05x = -1,600 divide both sides by 0.05 and remember that -/- = +

x = 32,000 This is the amount invested at 3%

The amount invested at 8% is 64,500-32,000 = 32,500

The peak of the mountain has a height of 14805 feet.

In this problem we find the case of an exponential function for atmospheric pressure (p), in pounds per square inch, in terms of height (x), in miles, whose expression is introduced below:

[tex]p(x) = 14.7 \cdot e^{- 0.21\cdot x}[/tex], for x ≥ 0.

If we know that p(x) = 8.164 lb / in², then the height of the peak of a mountain is:

[tex]8.164 = 14.7\cdot e^{-0.21 \cdot x}[/tex]

[tex]0.555 = e^{-0.21\cdot x}[/tex]

Then, by relationship between exponential and logarithmic functions and logarithm properties:

㏑ 0.555 = - 0.21 · x · ㏑ 1

㏑ 0.555 = - 0.21 · x

x = - (1 / 0.21) · ㏑ 0.555

x ≈ 2.804

Answer:

To find the remainder when f(x) is divided by (x-a) , we substitute x = a in the polynomial f(x) and we get the remainder.

remainder = f(a)

In this case, we have f(x)=5x^6-2x^2-5, and x+2 is the divisor and we substitute x=-2

so, remainder = f(-2) = 5*(-2)^6-2*(-2)^2-5 = -643

So, the remainder when f(x) is divided by x+2 is -643

V = 75.36 cm³

V = 75.36 cm³r = 2 cm

V = 75.36 cm³r = 2 cmπ = 3.14

Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.

h = 3V/(πr²)

h = 3×75.36/(3.14×2²)

2. t2(d2y/dt2)+t(dy/dt)+2y=sin t  ->  2nd. order linear differential equation

3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t3  ->  3rd. order non-linear differential equation

4. y''-y+y2=0  ->  2nd. order non-linear differential equation

The order of a differential equation is the highest derivative involved in the equation. For example, in the equation 1 + y2(d2y/dt2) + t(dy/dt) + y = et2, the highest derivative is the second derivative (d2y/dt2), so this equation is of 2nd order. Linearity is determined by whether the coefficients of each derivative are constants, or whether they depend on the function y and its derivatives. In this equation, the coefficient of the second derivative (1+y2) is not constant, so the equation is non-linear. Similarly, in equation t2(d2y/dt2)+t(dy/dt)+2y=sin t, the coefficient of the second derivative (t2) is constant, so the equation is linear.
