a) The new quadrilateral points are

S¹(5 ,-4) ,T¹(4,-1), U¹(1,0), V¹( 3 ,-3)

Step-by-step explanation:

Explanation:-

Malik draws quadrilateral STUV in the coordinate plane with vertices at $(-5, -4), T-4-1). U(-1,0) , V(-3,-3)

Malik reflects quadrilateral STUV across the y-axis then the transformed to

( x, y) → (-x ,y)

a) S(-5,-4)→S¹(-(-5) , -4)

S((-5,-4)→S¹(5 ,-4)

b) T(-4,-1)→ T¹(-(-4) ,-1)

   T(-4,-1)→ T¹(4,-1)

c) U(-1,0) → U¹(-(-1),0)

  U(-1,0) → U¹(1,0)

d) V(-3,-3)→ V¹( -(-3) ,-3)

   V(-3,-3)→ V¹( 3 ,-3)

final answer:-

The new quadrilateral points are

S¹(5 ,-4) ,T¹(4,-1), U¹(1,0), V¹( 3 ,-3)

Answer:

22.1°

here u do rise/ run

and the dots there are helping you to make it

you need to join them by doing rise over run

you go 3 to the right from the dot at the bottom and 3 up

which is 3/3 that equals to 1

look at the first one in a, the denomenator is 2. to make the denomentator 6 you have to multiply it with 3, since you cant change the denomentor without changing the numerator you also multiply it with 3.

Step-by-step explanation: look at the first one in a, the denomentor is 2, to make it 6 you have to multiply it with 3, since you cant change the denomenator without changing the numerator you have to also multiply with 3. repeat with the others. good luck

Answer:

The answer is

$ 225.23 monthly payments.

Answer:

A=$1.11

B=$19.61

Step-by-step explanation:

Convert 6% to decimal so move the decimal 2 places to the left so you get 0.06. You multiply 0.06 by 18.50 and you get 1.11.(Step A)

Then you add 18.50 to 1.11 to get $19.61.

Hope this helps! <3

Answer:

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Plane B is flying faster.

Step-by-step explanation:

The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:

Plane A

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

Plane B

The slope of the graph of plane B is:

[tex]v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}[/tex]

[tex]v = 460\,\frac{mi}{h}[/tex]

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Therefore, plane B is flying faster.

Rs 720

Cost of 1 m of cloth = 450/5= Rs 90

Cost of 8 m of cloth= 90*80= Rs 720

Answer:

The cost is Rs. 720

Step-by-step explanation:

The cost of 1 meter cloth is Rs.90

So 8 x 90 = 720

Step-by-step explanation:

The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

From the question, we are to calculate the surface area of the regular pyramid

The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base

∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]

Surface area of the pyramid = 2bh + b²

Where b is the base

and h is the perpendicular height of each triangular faces

In the given diagram,

b = 7

h = 10

∴ Surface area of the pyramid = 2×7×10 + 7²

Surface area of the pyramid =  140 + 49

Surface area of the pyramid = 189 units²

Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

Answer:

10 yards

Step-by-step explanation:

;)

The required length of the longer side is 10 yards.

Perimeter, is the measure of the figure on its circumference.

Here,
Let's assume that the length of one side of the rectangle is x yards. According to the problem, the other side of the rectangle is 3 yards longer than twice the length of this side. So, the length of the other side can be expressed as 2x + 3 yards.

The perimeter of a rectangle is the sum of the lengths of all its sides. So, we can write an equation to represent the problem:

Perimeter = 2 × length + 2 × width

Substituting the expressions for length and width, we get:

27 = 2(x) + 2(2x + 3)

27 = 2x + 4x + 6

27 = 6x + 6

21 = 6x

x = 3.5

So, the length of one side of the rectangle is 3.5 yards. The other side of the rectangle is 2(3.5) + 3 = 10 yards.

Therefore, the length of the longer side is 10 yards.
