Anybody know what is this? (I think it's not a compass)

Answer:

A = (5, 4)

B = (4, 3)

C = (5, 2)

D = (6, 3)

Step-by-step explanation:

Before I do anything, I will write the figure's coordinates for ABCD

A = (2, 3)

B = (1, 2)

C = (2, 1)

D = (3, 2)

Now, a translation means adding and or subtracting the x and y coordinates within the ordered pairs.

3 units right means add 3 units to the value of coordinate x. Coordinate x will always be for any horizontal movement (left and right).

1 unit up means add 1 unit to the value of coordinate y. Coordinate y will always be for any vertical movement (up and down).

Make these adjustments to each ordered pair:

A = (2 + 3, 3 + 1)

A = (5, 4)

B = (1 + 3, 2 + 1)

B = (4, 3)

C = (2 + 3, 1 + 1)

C = (5, 2)

D = (3 + 3, 2 + 1)

D = (6, 3)

Unfortunately I cannot graph the points for you, but if you mark each ordered pair I've given and then connect them together with lines, it will be graphed.

Answer:

D) m<4 = 137

Step-by-step explanation:

m<3 + 56  = 180

m<3 = 124

m<1 + 43 + 56 = 180

m<1 + 99 = 180

m<1 = 81

m<4 + 43 = 180

m<4 = 137

m<2 + <1 = 180

m<2 + 81 = 180

The football hits the ground at 6.53 seconds

The height function of the football is given as:

[tex]f(t) = -4.9t^2 + 30t + 13[/tex]

When the football hits the ground, f(t) = 0 i.e. the height of the football is 0.

So, we have:

[tex]-4.9t^2 + 30t + 13 = 0[/tex]

Using a calculator, we have:

[tex]t = \{-0.41, 6.53\}[/tex]

The value of time (i.e. t) cannot be negative.

So, we have:

[tex]t = 6.53[/tex]

Hence, the football hits the ground at 6.53 seconds

Scale factor is the ratio between corresponding measurements. And a pre image is basically an (original image) while an image is the translated version of the original.

I'm not sure what the best way to explain my answer is, but you can either multiply or divide to find the answer.

4 x 2.5 = 10

8 x 2.5 = 20

10 x 2.5 = 25

5 x 2.5 = 12.5

10/4 = 2.5

20/8 = 2.5

25/10 = 2.5

12.5/5 = 2.5

Answer:

area of the figure= 58.3ft²

Step-by-step explanation:

area of the figure= area of trapezoid+ area of a rectangle

area of the figure= [½(a+b)*height]+ (length*breadth)

area of the figure= [½(3+14)*3]+ (11*3)

area of the figure=25.3+ 33

area of the figure= 58.3ft².

The volume of a trapezoidal prism is 471.5 m³.

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The altitude is the measurement of the angle perpendicular to the parallel sides.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know volume of a trapezoidal prism is [(1/2)×(b₁+b₂)×h}×H.

Therefore, The volume of this trapezoid is,

= (1/2)×(24 + 19)×21 m³.

= (1/2)×(43)×21 m³.

= 471.5 m³.

n = -18/7

Step-by-step explanation:

Represent the number with n.

Then:

n - 6 = -6n - 24

Combining like terms results in 7n = -18, so n = -18/7

Answer:

Step-by-step explanation:

Here, we want to get the number of times the graph of the function intersects the x-axis

Mathematically we need to know the number of roots the function has

We can get this by the use of the discriminant

This is:

D = b^2 - 4ac

b is the coefficient of x which is 0 here

a is the coefficient of x^2 which is 1 here

c is the last number which is 2

So;

D = 0^2 -4(1)(2) = 0-8 = -8

the discriminant value is negative

This means there are no real roots

x-y plane is used for real numbers and thus since there are no real roots, the graph of the equation will not intersect any point on the x-axis

Answer:

Length of Radius of large circle= 8

Lenght radius of first circle= 2

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION

The sum of the areas of two circles is 80π square meters. Find the length of a radius of each circle if one of them is twice as long as the other.

What is the radius of the larger circle?

Area of a circle can be calculated by Below formula

A = πr^2............eqn(1)

Let ( X) = area of first circle

Y= the area of second circle

Rx= radius of first circle

Ry = radius of second circle

From the question, we know that

[X+ Y] = 80π .......eqn(2)

Substitute the radius formula for the area,

[π(Rx)^2 + π (Ry)^2] = 80π ......eqn(3)

But from the question, Radius of second circle is twice of the second one, then

Ry = 2Rx ..........eqn(4)

If we substitute eqn (4) into eqn(3)

[ π(Rx)^2 + π (2Rx)^2 = 80π

If factorize π out, then cancel it out

π[(Rx)^2 + π (2Rx)^2 = 80π

Then we have

(Rx)^2 + 4(Rx)^2 = 80

5(Rx)^2 = 80

(Rx)^2= 80/5

(Rx)^2= 16

(Rx)= 4

From eqn(4)

Ry = 2Rx

Ry= 2(4)

Ry= 8

Rx= 2 and Ry= 8

Hence, radius of first circle= 2

Lenght Radius of second circle= 8

Answer:

D. P(10|blue)

Step-by-step explanation:

The correct expression for the probability of selecting a blue piece of paper given that it has the number 10 on it is:

C. P(blue|10)

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Here, "blue|10" means "blue given 10," which represents the conditional probability of selecting a blue paper given that the selected paper has the number 10 on it.

The formula for conditional probability is:

P(A|B) = P(A and B) / P(B)

In this case, A represents the event of selecting a blue piece of paper and B represents the event of selecting a paper with the number 10 on it.

We know that there are 10 blue pieces of paper and each color has 10 numbered pieces, so the total number of papers is 10+10+10=30.

Thus, the probability of selecting a paper with the number 10 on it is:

P(B) = 3/30 = 1/10

Out of the 10 blue pieces of paper, only one has the number 10 on it. Thus, the probability of selecting a blue piece of paper given that it has the number 10 on it is:

P(A and B) = 1/30

Therefore, the probability of selecting a blue piece of paper given that it has a number 10 on it is:

P(blue|10) = P(A and B) / P(B) = (1/30) / (1/10) = 1/3

Answer:

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."

15 * 8p = £1.20

15 pencils

"Then I will buy as many rulers as possible."

£5 - £1.20 = £3.80

£3.80/30p = 12 remainder 20p

12 rulers

"With my change, I will buy more pencils.”

20p/8p = 2 remainder 4 p

2 pencils

Total pencils: 17

Total rulers: 15
