Step-by-step explanation:

a.) the maximum is just the vertex

-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum

which in height is

-4.9*3.5714^2+35*3.5714 +1= 63.5 metres

b.) for this just plug in 2

-4.9*2^2+35*2+1= 51.4 metres

c.) just plug in f(0) =1 meter

d.) find the x intercepts (using the quadratic formula)

[tex]\frac{-35-\sqrt{35^2-4*-4.9*1}}{2*-4.9}=7.17131519096[/tex] seconds

1. no 2: yes 3: yes 4. no 5.no 6. no

Step-by-step explanation:

Answer:

y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (2, - 3 ) , then

y = a(x - 2)² - 3

To find a substitute (4, 6 ) into the equation

6 = a(4 - 2)² - 3 ( add 3 to both sides )

9 = a(2)² = 4a ( divide both sides by 4 )

[tex]\frac{9}{4}[/tex] = a

y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3 ← in vertex form

smaller --- x

larger ---- x+10

x(x+10) = 56

x^2 + 10x = 56

x^2 + 10x + 25 = 56 + 25

(x+5)^2 = 81

x+5 = 9

x=4

one is 4, the other is 14

Hope this helps you!

Answer:

x=33 ; y=23

Step-by-step explanation:

Given that x+y=56 and x-y=10

Solve for either variable.

x=y+10

Substitute, replace, your solved variable in the other equation

(y+10)+y=56    Subtract 10 on both sides

2y=46     Divide by 2

y=23        Substitute answer into a given equation

x+23=56    Subtract 23 on both sides

x=33

The missing length of the given triangle divided into two right-angled triangle is 24.

The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Here is the solution in more detail:

The ratio 60:36:x can be written as 2:1:x.

This means that the ratio of the lengths of the three segments is 2:1:x.

The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Therefore, the missing length is 24.

All the answers to the various operations given from question 1 to 6 have been explained and answered below.

1) We want to use order of operations to solve;

105 - 7² + (72 ÷ 9)

From order of operations which is BODMAS.

First operation for our given expression is bracket. Thus;

72 ÷ 9 = 8

Thus, we now have;

105 - 7² + 8

Next is addition;

7² + 8 = 57

Thus, we now have;

105 - 57 = 48

2)   884284

   - 349407

      534877

3) 6 ÷ ²/₇

⇒ 6 × ⁷/₂

⇒ 21

4) Kevin makes $78.37 per day. Thus;

Amount he makes in 7 days = 78.37 × 7

⇒ $548.59

5) Product of 1389 and 6.58

⇒ 1389 × 6.58

⇒ 9139.62

6) We want to use distributive property to express 27 + 60.

Now, in distributive property, it implies that;

a(b + c) = ab + ac

Thus, let us get the greatest common factor of 27 and 60 and factorize it out.

GCF of 27 and 60 is 3. Thus;

27 + 60 = ((3*9) + (3*20))

⇒ 3(9 + 20)

⇒ 3(29)

⇒ 107

Answer:

x = 72° , y = 54°

Step-by-step explanation:

x and 108° are adjacent angles on a straight line and sum to 180°

x + 108° = 180° ( subtract 108° from both sides )

x = 72°

The vertex of the triangle on the left is vertically opposite x and is congruent

vertex = 72°

The sum of the 3 angles in the triangle = 180° , that is

y + y + 72° = 180°

2y + 72° = 180° ( subtract 72° from both sides )

2y = 108° ( divide both sides by 2 )

y = 54°

Answer:

so the answer is y=54°

Answer: 24

Step-by-step explanation: 180-114=66

66+90=156

180-156=24

Answer:

∠ A = 59°, ∠ B = 48° , ∠ C = 73°

Step-by-step explanation:

The interior angles of a triangle sum to 180°

sum the 3 angles and equate to 180

x + x - 11 + 73 = 180

2x + 62 = 180 ( subtract 62 from both sides )

2x = 118 ( divide both sides by 2 )

x = 59

Then

∠ A = x = 59°

∠ B = x - 11 = 59 - 11 = 48°

∠ C = 73°

Answer:

<A = 149*

<B = 138*

<C = 73*

Step-by-step explanation:

There are 360* total inside a triangle.

We subtract 73 from 360 to find the combined number of both angles a and b.

360-73 equals 287, so we know that both angles a and b add up to equal 287.

Since angle a equals x and angle b equals x - 11, we would combine the two expressions to find x. When we find x, it will allow us to know what both angles a and b equals to. So we combine x and x- 11, set it equal to 287, and solve for x.

x + x - 11 = 2x-11.

287 = 2x - 11

(Add eleven to both sides)

298 = 2x (divide both sides by two)

X = 149

Since angle a equals x, we know that angle a Is 149*.

And since angle b is x - 11, we take 149, subtract it by 11, and we get 138.
