X - the percent increase

25+25x=35 \ \ \ |-25 \\
25x=10 \ \ \ |\div 25 \\
x=\frac{10}{25} \\
\Downarrow \\
x=\frac{10}{25}=\frac{10 \times 4}{25 \times 4}=\frac{40}{100}=40\%

The answer is C. 40% increase.

Ana dives into a pool off of a springboard high dive. Her height (in meters above the water), x xx seconds after diving, is mode
vovikov84 [41]

Answer: Ana will hit the water after 3 seconds.

Step-by-step explanation:

The exercise gives you the following function which models Anna's height  above the water (in meters) after diving "x" seconds:

h(x)=-5(x+1)(x-3)

You can rewrite the function with h(x)=y:

y=-5(x+1)(x-3)

In order to calculate the number of seconds Ana will hit the water after diving, the procedure is:

- Substitute y=0 into the function:

 0=-5(x+1)(x-3)

- Solve for "x".

By the Zero Product Property, you know that if a* b = 0, then a=0 or b=0.

Then you get:

x=-1\ or\ x=3

- Choose the positive value (x=3)

Then, Ana will hit the water after 3 seconds.

Which of the following is not a correct form of the quadratic function?
aleksklad [387]

Answer:

The squared form is not a correct form of the quadratic function.

Step-by-step explanation:

Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.

As the general form and the standard form of quadratic equation is

y=ax^2+bx+c where a,b and c are constant.

Also, the vertex form is

y=m(x-a)^2+b where (a,b) is vertex.

Only the three forms of quadratic equation exist. No other form like squared form exist.

Hence, the squared form is not a correct form of the quadratic function.

I am struggling with triangles missing angles with the formula if you could explain your answer step by step that would be great
Alborosie

Answer:

See below.

Step-by-step explanation:

The 3 angles of all triangles add up to 180 degrees.

An isosceles triangle has 2 of its angles equal.

So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.

So the other 2 angles are equal and their measure is (180 - 130) / 2

= 50 / 2

= 25 degrees.

The 2 equal angles are both 25 degrees.
