4.) 32 answer

Step-by-step explanation:

2×2 is 4

4× 8 is 32

the correct answers are E(-4, 5) and F(3, 2). According to given probabilities  condition

How to solve the question?

To find the coordinates of Checkpoints E and F, we need to first understand what is meant by "located at CD's location in a 180° rotation of the course."

A 180° rotation means that we flip the course upside down, with the line segment connecting Checkpoints C and D acting as the axis of rotation. This means that Checkpoints E and F will be on the same line as CD, with E being the reflection of C and F being the reflection of D across the line CD.

To find the coordinates of E, we reflect C across the line CD. To do this, we first find the slope of the line CD:

slope = (2 - 5) / (-3 - (-4)) = -3

The midpoint of CD is:

midpoint = ((-3 + (-4))/2 , (2 + 5)/2) = (-3.5, 3.5)

The line perpendicular to CD passing through the midpoint has slope -1/(-3) = 1/3. Using point-slope form, we can find the equation of this line:

y - 3.5 = (1/3)(x + 3.5)

Simplifying, we get:

y = (1/3)x + 4

To reflect C across CD, we can find the intersection point of this line with the line passing through C and CD. This line has slope -3 and passes through (-4, 5). Using point-slope form, we can find its equation:

y - 5 = (-3)(x + 4)

Simplifying, we get:

y = -3x - 7

Setting these two equations equal to each other, we get:

(1/3)x + 4 = -3x - 7

Solving for x, we get:

x = -4

Substituting this value back into either equation, we get:

y = 5

Therefore, the coordinates of Checkpoint E are (-4, 5).

To find the coordinates of F, we reflect D across CD. We can use a similar method as above to find the line passing through D and CD:

slope = (2 - 5) / (-3 - (-4)) = -3

y - 2 = (-3)(x + 3)

Simplifying, we get:

y = -3x - 7

To reflect D, we find the intersection point of this line with the line perpendicular to CD passing through the midpoint:

y - 3.5 = (1/3)(x - (-3.5))

Simplifying, we get:

y = (1/3)x + 4

Setting these two equations equal to each other, we get:

(1/3)x + 4 = -3x - 7

Solving for x, we get:

x = 3

Substituting this value back into either equation, we get:

y = 2

Therefore, the coordinates of Checkpoint F are (3, 2).

So the correct answers are E(-4, 5) and F(3, 2).

Step-by-step explanation:

the total number of rows will be 15 + 7 = 22 rows. This is the least number of rows that James' brother can make while arranging the blocks in rows such that each row has the same number of blocks and contains only one color.

How to solve the question?

To find the least number of rows, we need to determine the greatest common divisor (GCD) of 56 and 120, since each row must have the same number of blocks. We can use the Euclidean algorithm to find the GCD:

120 = 2 x 56 + 8

56 = 7 x 8 + 0

Therefore, the GCD of 56 and 120 is 8. This means that each row must have 8 blocks, and there will be a total of (56+120) = 176 blocks to be arranged.

Since each row can have either only yellow or only black blocks, we need to determine which color will have the greater number of rows. To do this, we can divide the total number of blocks by the number of blocks in each row:

Yellow blocks:

Number of rows = 56 ÷ 8 = 7 rows

Black blocks:

Number of rows = 120 ÷ 8 = 15 rows

Since there are more black blocks, we will use 15 rows of black blocks. Each row will have 8 blocks, so there will be a total of (15 x 8) = 120 black blocks.

We can then use the remaining 56 yellow blocks to create rows of only yellow blocks. Each row will have 8 blocks, so there will be a total of (56 ÷ 8) = 7 yellow rows.

Therefore, the total number of rows will be 15 + 7 = 22 rows. This is the least number of rows that James' brother can make while arranging the blocks in rows such that each row has the same number of blocks and contains only one color

Answer:

  2. 139π/90 radians ≈ 4.852

  3. -(9√5 +8√7)/77

  4. 2+√3

Step-by-step explanation:

You want exact answers involving various trig identities and angle sum formulas.

There are π radians in 180°, the number of radians in 278° is ...

  278°(π/180°) = (278/180)π

  278° = (139/90)π radians ≈ 4.852 radians

The cosine of the sum of angles is ...

  cos(x +y) = cos(x)cos(y) -sin(x)sin(y)

The relationship between sine and cosine is ...

  cos(x) = ±√(1 -sin(x)²)

  sin(x) = ±√(1 -cos(x)²)

The signs will depend on the quadrant of the angle.

To use the angle sum relation, we need the sine of the angle whose cosine is given, and vice versa.

  sin(arccos(-2/7)) = -√(1 -(-2/7)²) = -(√45)/7 = (-3/7)√5 . . . . in QIII

  cos(arcsin(-3/11)) = √(1 -(-3/11)²) = (√112)/11 = (4/11)√7 . . . . in QIV

The cosine of the sum of the angles is then ...

  cos(arccos(-2/7) +arcsin(-3/11)) = (-2/7)(4√7/11) -(-3√5)/7·(-3/11)

  = -8√7/77 -9√5/77

  cos(x +y) = -(9√5 +8√7)/77

The formula for the tangent of the sum of angles is ...

  tan(x +y) = (tan(x) +tan(y))/(1 -tan(x)tan(y))

We know that tan(π/4) = 1 and tan(π/6) = 1/√3, so the tangent of the sum of the angles is ...

  tan(π/4 +π/6) = (1 +1/√3)/(1 -(1·1/√3)) = (√3 +1)/(√3 -1) = (√3 +1)²/2

  tan(π/4 +π/6) = 2 +√3

2) 278° × π/180 = 4.852rad

3) in the above given expressions, Sin(x) is negative.

Using Pythagorean rule, we can state:

sin(x ) = √(1 - cos^2(x)) =

√(1 - (-2/7)²)

= -3√(3)/7

Also,

given that cos( y) is positive, we c  n also use the Pythagorean idetity

cos  (y) = √(1 - sin ²(y) )

= √(1 - (-3/1 1)²)

= 8√(2)/11

substituting into cos (x + y)


cos(x+y) = cos(  x)cos (y ) - sin (x) sin(y)

= (-2/7)( 8 √(2)/11) - (-3√(3)/7) ( -3/11)

= -1 6 √(2) /77 + 9√( 3)/ 77

= -0.09141506142

The exact value is approximately -0.0914

3)

Using the formula for tangent of sum of angles we say

tan( ( π/4) + (π/6) )   = (tan ( π / 4) + tan (π/6))/(1 - tan ( π/4) tan( π/6))

Sutstituting ....

tan ((  π/4) + ( π/6) )  = (1 + √ 3/3)/( 1 - √ 3 /3 )

tan( (π/ 4) + (π /6 )) =   (1 + √3/   3) (1 + √3/3 )]/ [(1 - √3/ 3)(1 + √3/3)]

Simplifying

  tan ( (π /4) + ( π/6) ) = ( 2 + √3 )/  ( 2 - √ 3)

Answer: To find the area of a triangle, we can use the formula:

Area = (base x height) / 2

However, in this problem, we don't have the height of the triangle directly. Instead, we have the lengths of three sides of the triangle.

To find the height, we can use Heron's formula, which allows us to calculate the area of a triangle when we know the lengths of all three sides:

Area = √(s(s-a)(s-b)(s-c))

where a, b, and c are the lengths of the sides of the triangle, and s is the semi-perimeter (half of the perimeter) of the triangle:

s = (a + b + c) / 2

Once we have the area of the triangle, we can use the given price per square foot to calculate the cost of the lot.

So, to apply this to the problem at hand, we can first calculate the semi-perimeter of the triangle:

s = (94 + 188 + 168) / 2 = 250

Next, we can use Heron's formula to find the area of the triangle:

Area = √(250(250-94)(250-188)(250-168)) ≈ 7329.53 square feet

Finally, we can calculate the cost of the lot by multiplying the area by the price per square foot:

Cost = 7329.53 x $3 = $21,988.59

Therefore, the approximate cost of the triangular lot is $21,988.59.

Martina is learning different kinds of Latin dance she went to 6 salsa lessons and 12 rumba lessons each lessons cost 4$ let t equal the total number of lesson, the total cost of the lessons is $72.

The problem gives us two pieces of information:

1. Martina attended 6 salsa lessons and 12 rumba lessons, which means she attended a total of 18 lessons in total.

2. Each lesson costs $4.

To find an equation for the total number of lessons (t), we simply add the number of salsa lessons and rumba lessons:

t = 6 + 12

t = 18

So the total number of lessons Martina attended is 18.

To find an equation for the total cost of the lessons (c), we can multiply the total number of lessons by the cost per lesson:

c = t x 4

c = 18 x 4

c = 72

So the total cost of the lessons Martina attended is $72.

Thus, the equation for the total number of lessons is t = 6 + 12 = 18 and the equation for the total cost of the lessons is c = t x 4 = 18 x 4 = 72.

A protractor, a tool with a semicircular or circular scale and degree markings, can be used to measure angles. Angles may also be labelled using symbols, such as ∠ABC or ∠PQR, in which the letter in the middle of the symbol designates the vertex of the angle.

An auxiliary line that is parallel to XZ given is the triangle formed by XYZ and AY.
