Answer:

Yes

Step-by-step explanation:

A circle can be circumscribed around the four vertices of a quadrilateral if and only if,

both pair of opposite angles inscribed in the quadrilateral are supplementary to each other. By supplementary to each other we mean that their sum is equal to 180°.

In this case we have opposite interior angles supplementary to each other hence we can circumscribe a circle around it. Such Quadrilateral are called cyclic quadrilateral.

Answer:

The answer is True

Step-by-step explanation:

I just got it correct.

B is the correct answer , it is incorrect.

Answer:

(b) is incorrect

Step-by-step explanation:

Applying Pythagoras' theorem to the right triangle.

The square on the hypotenuse (t ) is equal to the sum of the squares on the other 2 sides, that is

t² = r² + s² ( subtract r² from both sides )

t² - r² = s² ← is a correct equation → (a)

The answer is: [tex]f(t)=-4t^{2}+t+3[/tex]

Since we are given a quadratic function, we need to write it using the standard form of quadratic function (parabola).

The given function is:

[tex]f(t)=3-2t.2t=+t[/tex]

The standard form of a parabola is:

[tex]f(t)=a^{2}+bx+c[/tex]

Where,

a is equal to the quadratic variable coefficient

b is equal to the linear variable coefficient

c is the constant number

So, writing the function in the standard form will be:

[tex]f(t)=3-2t*2t+t=3-4t^{2}+t=-4t^{2}+t+3[/tex]

[tex]f(t)=-4t^{2}+t+3[/tex]

Where,

[tex]a=-4\\b=1\\c=3[/tex]

If x=6 and y=3 is 9_______________________________________

Answer:

x = 2

Step-by-step explanation:

The product of the external part times the entire secant of one secant is equal to the external part times the entire secant of the other secant, that is

(x + 4)(x + 5) = (x + 1)(x + 12) ← distribute factors on both sides

x² + 9x + 20 = x² + 13x + 12 ( subtract x² from both sides )

9x + 20 = 13x + 12 ( subtract 13x from both sides )

- 4x + 20 = 12 ( subtract 20 from both sides )

- 4x = - 8 ( divide both sides by - 4 )

Answer:

A. $7,764.62

Step-by-step explanation:

The amount you will have after 10 years if you invest $2,500 into an account that pays 12% per year, compounded annually is given by

[tex]A=P(1+r\%)^t[/tex]

where [tex]t=10[/tex] years

[tex]r\%=0.12[/tex]

and P=$2,500

We substitute these values into the formula to obtain;

[tex]A=2500(1+0.12)^{10}[/tex]

This will give us;

[tex]A=2500(1.12)^{10}[/tex]

[tex]A=7764.6205[/tex]

We round to the nearest hundredth to obtain;

[tex]A=7,764.62[/tex]

The correct choice is A.

Answer:

Option A

Step-by-step explanation:

We must use the compound interest formula:

[tex]A = P(1 + r)^t[/tex]

Where

P is the initial amount = 2500

r is the annual interest rate =0.12

t is time in years = 10

A is the final amount

Then we substitute these values in the formula:

[tex]A = P(1 + r)^t\\\\A = 2500(1+0.12)^10\\\\A = 7,764.62[/tex]

Answer:

B) x = 1

C) x = 4

Step-by-step explanation:

Given:

f(x) = 2x

g(x) = 2^x

We have to find at what value of x, the above two functions are equal in value.

Now we have to check with the each options.

When x = 0, f(0) = 2(0) = 0 ; g(0) = 2^0 = 1 [Anything power 0, is 1]

When x = 1, f(1) = 2(1) = 2 ; g(1) = 2^1 = 2.

when x = 2, f(2) = 2(2) = 4; g(2) = 2^2 = 4

when x = 3, f(3) = 2(3) = 6, g(3) = 2^3 = 8

when x = 4, f(4) = 2(4) = 8, g(4) = 2^4 = 16

The two functions are equal in value when x = 1 and x = 2.

Final answer:

The value(s) of x for which the equation f(x) = 2x and g(x) = 2ˣ are equal are x = 1 and x = 2, as those are the points where the two functions have the same value.

Explanation:

The student seems to be asking for which value(s) of x the equations f(x) = 2x and g(x) = 2ˣ are equal. To find the solution, we need to identify the point where the two functions intersect, by setting them equal to each other and solving for x.

So we set up the equation 2x = 2ˣ and look for solutions. At first glance, it seems there are two obvious solutions:

When x = 1, f(x) = 2 x 1 = 2 and g(x) = 2¹ = 2, so the statement f(x) = g(x) is true.

When x = 0, f(x) = 2 x 0 = 0 and g(x) = 2⁰ = 1, so the statement f(x) = g(x) is not true.

Testing the other provided options similarly, you'll find that:

For x = 2, f(x) = 4 and g(x) = 4, hence f(x) = g(x) is true.

For x = 3, f(x) = 6 and g(x) = 8, hence f(x) = g(x) is not true.

For x = 4, f(x) = 8 and g(x) = 16, hence f(x) = g(x) is not true.

The correct answers are x = 1 and x = 2, where the equation f(x) = g(x) holds true.

Answer:

Step-by-step explanation:

(2x-1)²=x²+4²

4x²-4x+1=x²+16

3x²-4x-15=0

a=3   b=-4   c= -15

D=b²-4ac

=16-4*3*(-15)=196

x1=-b+√D/2a=4+14/6=3

x2=-b-√D/2a=4-14/6=-10/6=-5/3

Answer:

x = 3

Step-by-step explanation:

Using Pythagoras' theorem on the right triangle, then

(2x - 1)² = 4² + x² ← expand parenthesis on the left side and simplify

4x² - 4x + 1 = 16 + x² ( subtract 16 + x² from both sides )

3x² - 4x - 15 = 0 ← in standard form

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × - 15 = - 45 and sum = - 4

The factors are - 9 and + 5

Use these factors to split the x- term

3x² - 9x + 5x - 15 = 0 ( factor the first/second and third/fourth terms )

3x(x - 3) + 5(x - 3) ← factor out (x - 3)

(x - 3)(3x + 5) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - [tex]\frac{5}{3}[/tex]

However, x must be greater than zero

Hence x = 3 cm

The area of the pattern is calculated by finding the area of the circle, semicircles, and quarter-circles separately and then adding them together. The area of the pattern is approximately 1005.31 cm^2.

To find the area of the pattern, we need to calculate the area of the circle, semicircles, and quarter-circles separately. The area of a circle is found using the formula A = πr^2, where r is the radius. So, the area of the circle is A = π(8)^2 = 64π cm^2. The area of a semicircle is half the area of a circle, so it is 32π cm^2. The area of a quarter-circle is a quarter of the area of a circle, which is 16π cm^2. To find the total area of the pattern, we add the areas of the circle, semicircles, and quarter-circles: 64π + 4(32π) + 8(16π) = 64π + 128π + 128π = 320π cm^2. Rounding to the nearest hundredth, the total area of the pattern is approximately 1005.31 cm^2.

Finding the areas of the circles, semicircles, and quarter-circles separately and combining them together yields the pattern's overall area. The pattern's estimated area is 1005.31 cm^2.

To determine the area of the pattern, individual areas of the circle, semicircles, and quarter-circles are computed separately.

Utilizing the formula

A = πr^2

for a circle with a radius (r) of 8 cm, the circle's area is 64π cm^2.

The semicircles, constituting half the circle's area, total 32π cm^2 each.

Quarter-circles, representing a quarter of the circle's area, contribute 16π cm^2 each.

Combining these, the pattern's total area is calculated as 64π + 4(32π) + 8(16π) = 320π cm^2.

Rounded to the nearest hundredth, the total area is approximately 1005.31 cm^2.

Answer:

-3 143/1000

Step-by-step explanation:

To write -3.143 in its equivalent fraction form, multiply the whole number part by the place value of the decimal and add it to the decimal part multiplied by the place value. The resulting fraction is -3143/1000.

To write the decimal number -3.143 in its equivalent fraction form, we first need to determine the place value of each digit. The number -3.143 has three digits after the decimal point, so the fraction's denominator will be ten, raised to the power of three, which is 1000. The fraction's numerator will be the whole number part of the decimal (in this case, -3) multiplied by 1000, plus the decimal part (0.143) multiplied by 1000.

Therefore, the equivalent fraction form of -3.143 is:

-3.143 = (-3 * 1000 + 0.143 * 1000) / 1000 = -3143 / 1000

Answer: [tex]\frac{7}{16}hour[/tex]

Step-by-step explanation:

You know that the total time was: 7/8 hour

You also know that they spent 1/2 of the time at the beach.

Therefore, to calculate the time  Zach and his dog spend at the beach (which you can call x) , you must multiply both fractions (7/8 and 1/2).

Then, you obtain the following result:

[tex]x=\frac{7}{8}hour*\frac{1}{2}\\\\x=\frac{7}{16}hour[/tex]

Zach and his dog spent 7/16 of an hour at the beach. This was calculated by multiplying the total walking time of 7/8 of an hour by 1/2, which represents the proportion of the total time spent at the beach.

The question is asking for the amount of time that Zach and his dog spent at the beach. We know that they spent 1/2 of their total walking time, which was 7/8 hour, at the beach. To find this, we simply need to multiply those two fractions together. Multiply the numerators (top numbers) together to get the numerator of the product, and multiply the denominators (bottom numbers) together to get the denominator of the product. 1 * 7 equals 7, and 2 * 8 equals 16, so the product is 7/16 of an hour. This is the amount of time they spent at the beach.

An atom containing two more electrons than protons has a net charge of negative two (-2), as determined by the difference in number of positive protons and negative electrons.

An atom which has two more electrons than protons has a charge of -2. The charge of an atom is determined by the difference between the number of protons and electrons. Protons have a charge of +1 and electrons have a charge of -1. Hence, if the atom has two more electrons than protons, it will have a charge of -2 because electrons contribute a negative charge. For instance, for an atom with 2 protons (+2 charge) and 4 electrons (-4 charge), the overall charge would be -2.
