I had trouble plotting the midpoint lol but can someone plz help me :c

Answers

midpoint is (-1 and -1.5)

Answer:

Step-by-step explanation:

midpoint rule is x2+x1 / 2 , y2+y1 / 2

where point one is P1 = (x1,y1) = (4,3)

and point two is P2 = (x2,y2) = -6,-6

for x then, -6+4 / 2 = -2 / 2 = - 1

for y then, -6+3 / 2 = -3 / 2 = - [tex]\frac{3}{2}[/tex]

mid point is ( -1 , - [tex]\frac{3}{2}[/tex] )

450/30

15/3x =5

x= 5

5+2y= 315

5-5+2y =315-5

2y = 310

2y/2 = 310/2

y=155

Step-by-step explanation:

The triangle and the trapezoid have the same area. Base b2 is twice the length of base b1. What are the lengths of the bases of the trapezoid? The area of the triangle is 65 cm squared

Answers

Answer:

[tex]b_1 \approx 7.2[/tex]

[tex]b_2 \approx 14.4[/tex]

Step-by-step explanation:

Given

[tex]Area = 65cm^2[/tex] --- Area of the triangle

[tex]b_2 = 2b_1[/tex] --- the bases of the trapezoid

The missing parameters is:

[tex]h=6 cm[/tex] --- Trapezoid height

Required

Determine b1 and b2

Since the areas of the trapezoid and the triangle are the same, then:

[tex]Area = \frac{1}{2}(b_1 + b_2) *h[/tex]

So, we have:

[tex]65 = \frac{1}{2}(b_1 +b_2) * 6[/tex]

Substitute[tex]b_2 = 2b_1[/tex]

[tex]65 = \frac{1}{2}(b_1 +2b_1) * 6[/tex]

[tex]65 = \frac{1}{2}(3b_1) * 6[/tex]

[tex]65 = 3b_1 * 3[/tex]

[tex]65 = 9b_1[/tex]

Solve for [tex]b_1[/tex]

[tex]b_1 = \frac{65}{9}[/tex]

[tex]b_1 \approx 7.2[/tex]

Substitute [tex]b_1 \approx 7.2[/tex] in [tex]b_2 = 2b_1[/tex]

[tex]b_2 \approx 2 * 7.2[/tex]

[tex]b_2 \approx 14.4[/tex]

A mother bear and her cub catch fish from a river . The mother bear catch 10 fish the mother bear catch 5 times as many

Answers

Answer:

This doesn't make sense.

Step-by-step explanation:

If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.

This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.

The height of a falling pinecone can be represented by y = -16° +64 where t is the time in seconds
and y is the height of the pinecone in feet. Write and solve an equation to find the number of seconds it
will take for the pinecone to reach the ground.
A. 4 seconds
B. 6 seconds
C. 2 seconds
D. 1.5 seconds

Answers

Answer:

4 Seconds

Step-by-step explanation:

Let's say the height of the ground is set at y = 0.

Then, since 16 times 4 is 64, we substitute 4 for x.

But wait! x is being squared!

So we need to find out what squared is 4. It's 2.

So, with x being equal to two, y is equal to 0.

But what is the number of seconds? We actually got it first.

That means that the answer is 4.

The pinecone takes 4 seconds to reach the ground.

The polygons are regular polygons. What is the area of the shaded region?

Please my brain literally can’t process this...

Answers

Answer:

shaded Area hexagon = Around 281 squared feet

shaded area square 24 squared inches

Step-by-step explanation:

regular hexagon is made up of 6 equilateral triangles. All sides are equal

The formula for finding the area of a hexagon is Area = (3√3 s2)/ 2 where s is the length of a side of the regular hexagon.

Side big hexagon = 12

side small hexagon = 6

BIG A= (3√3 144)/ 2 = 374.1230...

small (3√3 36)/ 2 = 93.5307...

shaded = BIG minus small

374.1230... - 93.5307... = 280.5923... squared feet

BIG SQUARE diagonal = 8

area of a square using diagonals = ½ × d2 Square units.

= ½ × 64 = 32 Square units.

small square (diagolal 4)

½ × 16 Square units. = 8 square inches

Area shaded 32-8 = 24 square inches

if the ratio of milk and water in 45 litre is 7:2. if 4 litre water is added what will be the new ratio.

Answers

Answer:

5 : 2

Step-by-step explanation:

sum the parts of the ratio, 7 + 2 = 9 parts

Divide the quantity by 9 to find the value of one part of the ratio

45 litres ÷ 9 = 5 litres ← value of 1 part of the ratio , then

7 parts = 7 × 5 = 35 litres

2 parts = 2 × 5 = 10 litres

In 45 litres there is 35 litres of milk and 10 litres of water

Adding 4 litres of water gives

35 : 14 = 5 : 2

The roots of a quadratic function are 6 and -2. Which is a possible vertex of the function?

A (-2,-4)

B (-8,-2)

C (-2,0)

Is the letter A, thanks for you points

The possible vertex of the function is (2, -16).

What are Quadratic Functions?

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Let f(x) = ax² + b x + c be the function required.

Roots are 6 and -2.

Equation can be written in the factorized form as,

(x - 6) (x + 2) = 0

x² - 6x + 2x - 12 = 0

x² - 4x - 12 = 0

f(x) = x² - 4x - 12

Vertex of a function f(x) = ax² + b x + c is (h, k) such that h = - (b/2a) and k = f(h)

h = - (-4/2) = 2

k = f(2) = 4 - 8 - 12 = -16

Hence the vertex of the function is (2, -16).
