The measure of m∠BCA is equal to: C. 70°

In Mathematics and Geometry, a circle is a closed, two-dimensional curved geometric shape with no edges or corners.

Additionally, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis), and a full circle always has a measure of 360 degrees.

In this context, the sum of an angle around any point is equal to 360 degrees;

m∠(BOA) = 360 - 250

m∠(BOA) = 110°

Also, the sum of all the interior angles inscribed in this circle, CAOB = 360 degrees;

m∠BCA = 360 - (110 + 90 + 90)

m∠BCA = 70°

Step-by-step explanation:

The first step is to find the radius of the circle, which is half the diameter:

r = 5.6/2 = 2.8 inThe area of the entire circle is:

A = πr² = 3.14 x 2.8² = 24.616 in²To find the area of the sector, we need to multiply the area of the whole circle by the fraction of the circle represented by the central angle. Since the central angle is 130° out of 360° (a full circle), the fraction of the circle represented by the sector is:

130/360 = 13/36Therefore, the area of the sector is:

A = (13/36) x 24.616 = 8.912 in²Rounding to the nearest hundredth, we get:

A ≈ 8.91 in²Therefore, the area of the sector is approximately 8.91 in².

Step-by-step explanation:

To find the best prediction of the cost of the groceries nine years after the beginning of the study, we need to use the given data to find the values of a and b in the function C=a(b)x. So, the best prediction of the cost of the groceries nine years after the beginning of the study is $53.34.

To do this, we can use the first data point where x = 0:
30 = a(b)^0

This simplifies to:  

30 = a
So, we know that a = 30.

Next, we can use any other data point to solve for b. Let's use the second data point where x = 1:
32.10 = 30(b)^1

This simplifies to:
32.10 = 30b
b = 1.07
Now we can use the function C = 30(1.07)^x to find the best prediction of the cost of the groceries nine years after the beginning of the study:
C = 30(1.07)^9
C ≈ $53.34

Therefore, the best prediction of the cost of the groceries nine years after the beginning of the study is $53.34.

Answer: its D because Jews (Hebrew: יְהוּדִים, ISO 259-2: Yehudim, Israeli pronunciation: [jehuˈdim]) or Jewish people are an ethnoreligious group,[10] nation or ethnos[11][12] originating from the ancient Israelites[13][14][15] and Hebrews[16][17][18] of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated,[19][20] as Judaism is the ethnic religion of the Jewish people, although its observance varies from strict to none.[21][22]

Jews originated as an ethnic and religious group in the Middle East during the second millennium BCE,[9] in a part of the Levant known as the Land of Israel.[23] The Merneptah Stele of ancient Egypt appears to confirm the existence of a people of Israel somewhere in Canaan as far back as the 13th century BCE (Late Bronze Age).[24][25] The Israelites, as an outgrowth of the Canaanite population,[26] consolidated their hold in the region with the emergence of the kingdoms of Israel and Judah. Some consider that these Canaan-sedentary Israelites melded with incoming nomadic groups known as the "Hebrews".[27] The experience of life in the Jewish diaspora, from the Babylonian captivity and exile (though few sources mention this period in detail[28]) to the Roman occupation and exile, and the historical relations between Jews and their homeland in the Levant thereafter became a major feature of Jewish history, identity, culture, and memory.[29]

In the following millennia, Jewish diaspora communities coalesced into three major ethnic subdivisions according to where their ancestors settled: the Ashkenazim (Central and Eastern Europe), the Sephardim (initially in the Iberian Peninsula), and the Mizrahim (Middle East and North Africa).[30][31] Prior to World War II, the global Jewish population reached a peak of 16.7 million,[32] representing around 0.7 percent of the world population at that time. During World War II, approximately 6 million Jews throughout Europe were systematically murdered by Nazi Germany during the Holocaust.[33][34] Since then, the population has slowly risen again, and as of 2018, was estimated to be at 14.6–17.8 million by the Berman Jewish DataBank,[1] comprising less than 0.2 percent of the total world population.[35][note 1] The modern State of Israel is the only country where Jews form a majority of the population.

Answer:

The y-intercept is -3

Written as a point it is (0, -3)

Step-by-step explanation:

To find the y-intercept, let x = 0

(and to find x-intercepts, let y = 0)

So let's let x = 0

f(x) = x^2 + 2x - 3

y = x^2 + 2x - 3

y = 0^2 + 2(0) - 3

y = -3

This means the y-intercept is -3. The graph crosses the y-axis at -3. This is the point (0, -3).

The area of a right triangle with a height of 8 yards and a base of 17 yards is 136 square yards.

The area of a right triangle with a height of 8 yards and a base of 17 yards can use the formula for the area of a triangle:

Area = (base x height) / 2

Substituting the given values into the formula get:

Area = (17 x 8) / 2

Area = 136 square yards

The area of the right triangle is 136 yd².

To understand why this formula works can visualize the right triangle as half of a rectangle.

The height of the triangle is one side of the rectangle and the base of the triangle is the adjacent side of the other half of the rectangle.

The area of the rectangle is the product of its height and base is twice the area of the right triangle.

Answer:

A food manufacturer may use zero-rated goods in the manufacturing of a food product, but when the consumer buys the final product, it includes a VAT.

Step-by-step explanation:

This value is quite close to the doubling time approximation of 18 years that is often used for populations growing at a rate of 4% per year.

The given rate of growth = 4.1%

We know that,

The doubling time is the amount of time required for a population to double in size or value.

It is used to calculate population growth, inflation, resource extraction, commodities consumption, compound interest, the volume of malignant tumors, and a variety of other things that tend to develop over time. When the relative growth rate is constant (rather than the absolute growth rate), the amount grows exponentially and has a constant doubling time or period, which may be determined simply from the growth rate.

Formula for calculating the doubling time using logarithms is:

doubling time = ln(2) / (annual growth rate)

Since 41% = 0.041

doubling time = ln(2) / (0.041)

doubling time = 16.85 years

So the doubling time for South Sudan's population at this growth rate is approximately 16.85 years ≈ 18 years

In this question, measure of angle 4 is c. 60 degree. It has been calculated using properties of parallel lines.

It can be seen that in this question l and m are parallel lines and there is a transverse passing through it. We know through the properties of parallel lines that sum of ∠2 and ∠4 is 180° as they are consecutive interior angles and consecutive interior angles are supplementary meaning their sum is 180.

∠2 + ∠4 = 180° (consecutive interior angles)

120° + ∠4 = 180°

∠4 = 180 - 120

= 60°

Parallel lines are straight lines that never meet, no matter how far they are extended. Many pairs of angles are generated when two parallel lines are intersected by another line known as a transversal.

Some angles are congruent (equal), whereas others are supplementary (different).  Consecutive interior angles, also known as co-interior angles, develop on the inside of the transversal and are additional.

Answer:

9th term = 524288

Step-by-step explanation:

An equation we can use to find the nth term in a geometric sequence is:

[tex]a_{n}=a_{1}(r)^(^n^-^1^)[/tex], where

Step 1:  We're already given that a1 = 8 and that n = 9 (since we want to find the 9th term).  However, we need to find the common ratio by dividing two consecutive terms with the successive term being divided by the preceding term.  We can divide 32 by 8 to find r, the common ratio:

r = 32/8

r = 4

Thus, the common ratio of the sequence is 4

Step 2:  In order to find the 9th term of the sequence, we can plug in 8 for a1, 4 for r, and 9 for n and simplify:

[tex]a_{n}=8(4)^(^9^-^1^)\\a_{n}=8(4)^8\\a_{n}=8(65536) \\a_{n}=524288[/tex]

Thus, the 9th term of the geometric sequence is 524288.
