the discriminant formula is b^2-4ac

so plug the values from each equation into the formula and solve, the result is the value of the discriminant

if the number is negative, there are no real roots/x-int

if it is 0 there is one real root/x-intercepts

if it is positive it has 2 real roots/x-int

and to find the actual solutions you have to plug the values into the quadratic formula

Which pair of segments are corresponding parts of the congruent quadrilaterals that are pictured below?

Lunna [17]

Answer:

Segment A B and Segment Z W

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

Sides C D and Y X are congruent,

sides C B and Y Z are congruent,

sides Z W and A B are congruent,

sides A D and X W are congruent

ABCD≅WZYX

The corresponding sides are

AB and WZ

BC and ZY

CD and YX

AD and WX

That means

AB ≅ WZ

BC ≅ ZY

CD≅ YX

AD ≅ WX

The corresponding angles are

∠A and ∠W

∠B and ∠Z

∠C and ∠Y

∠D and ∠X

That means

∠A ≅ ∠W

∠B ≅ ∠Z

∠C ≅ ∠Y

∠D ≅ ∠X

therefore

The answer is

Segment A B and Segment Z W

A rocking horse has a weight limit of 60pounds. What percentage of the weight limit is 33 pounds? What percentage of the weight

bixtya [17]

Answer:

The percentage is 55% when weight limit is 33 pounds.

The percentage is 190% when weight limit is 114 pounds.

The 95% of the limit weighs 57 pounds.

Step-by-step explanation:

Given:

Weight limit of rocking horse = 60 pounds.

We need to find:

a) What percentage of the weight limit is 33 pounds.

b)What percentage of the weight limit is 114 pounds.

c) What weight is 95% of the limit.

Now Solving for a we get;

Weight limit = 33 pounds

Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{33}{60}\times100 = 55\%$

Hence The percentage is 55% when weight limit is 33 pounds.

Now Solving for b we get;

Weight limit = 114 pounds

Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{114}{60}\times100 = 190\%$

Hence The percentage is 190% when weight limit is 114 pounds.

Now Solving for c we get;

Percentage Weight = 95%

Now Amount of weight limit can be calculated by multiplying Percentage weight limit with total weight limit and then Dividing by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{95}{100}\times60 = 57 \pounds$

Hence The 95% of the limit weighs 57 pounds.

Basically always use a^2 + b^2 = c^2 it gives you your A and C so subtract your A from you C and you have your B
