Find The Value Of X In The TrapezoidPlease Help Me Fast Ill Give You Brainly If Its Right

Answers

Answer 1

Answer: 9.95

Step-by-step explanation:

in similar trapezoids a rearranged formula can be used to solve for the missing base:

[tex]c^{2} =ab[/tex]  ⇒ [tex]c=\sqrt{ab}[/tex]

a = the top of the trapezoid

b= the base of the trapezoid

c = the missing base

[tex]c=\sqrt{(9)(11)}[/tex]

[tex]c = 9.949[/tex]

explanation i learned it in 5th grade lol

The size of the angle x is 13°

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

From the figure,

Let the triangle having ∠x have the following angles:

∠A and ∠B.

Now,

∠A is opposite to 85°.

So,

∠A = 85°

98° and one angle are corresponding angles.

So,

One angle = 98°

Now,

One angle and ∠B is a straight angle.

So,

∠B + 98 = 180

∠B = 180 - 98

∠B = 82°

Now,

The sum of the triangle is 180.

This means,

x + 82 + 85 = 180

x = 180 - 167

x = 13

Thus,

The value of x is 13.

What’s the question?

Step-by-step explanation:

Do you agree with the statement that " cubic functions must have at least 1 x-intercept but not more than 3, whereas quadratic functions may or may not have x-intercepts

Answers

Answer:

Yes, I agree

Step-by-step explanation:

For the cubic function

A cubic function is represented as:

[tex]f(x)=ax^3+bx^2+cx+d[/tex]

A cubic function may have 1, 2 or 3 x intercepts. This is shown below

For 3 x intercepts

[tex]y = x^3 - x[/tex]

Equate y to 0

[tex]x^3 - x = 0[/tex]

Expand

[tex]x(x^2 - 1) = 0[/tex]

Express [tex]x^2 - 1[/tex] as difference of two squares

[tex]x(x - 1)(x +1 ) = 0[/tex]

x = 0 or 1 or -1

For 2 x intercepts

[tex]y = x^3 - x[/tex]

[tex]y =(x-5)^2)(x+7)[/tex]

Equate y to 0

[tex](x-5)^2(x+7) = 0[/tex]

Expand

[tex](x-5)(x-5)(x+7) = 0[/tex]

x= 5 or x = -7

For 1 x intercept

[tex]y = x^3[/tex]

Equate y to 0

[tex]x^3 = 0[/tex]

Take cube roots of both sides

[tex]x = 0[/tex]

It has been shown above that a cubic function may have 1, 2 or 3.

So, I agree to the statement

For the quadratic function

A quadratic function will not have any x intercept when the function can not be factorized;

E.g.

[tex]y = x^2 + x + 17[/tex]

The above function has no x intercept.

A quadratic function will have at least 1 x intercept when the function can be factorized;

E.g.

[tex]y = x^2- 6x + 9[/tex]

Equate y to 0

[tex]x^2- 6x + 9 = 0[/tex]

Expand

[tex]x^2 - 3x - 3x + 9 = 0[/tex]

[tex](x - 3)(x-3) = 0[/tex]

[tex]x = 3[/tex]

We've shown that a quadratic may have no x intercept, and it may also have x intercept(s)

Hence, I agree to both statement

Explain why Kym is incorrect.

Answer:

Kym is wrong because instead of 25% it would be 50 percent

Step-by-step explanation:

Answer:

Sample Response: The ratio of boys to total students was 25:50. Written as a fraction, this is 25/50. Rewrite the fraction with a denominator of 100 to 50/100. So 50% of the students were boys.

So, you want to get 'x' by itself

0.25x + 7.5 = 15

           - 7.5   -7.5

0.25x = 7.5

---------   ------

0.25     0.25

x = 30

0.25x+7.5=15
subtract 7.5 from 15
0.25x=7.5
divide 7.5 by 0.25 to get (x) by itself.

x=30

The distance between town a and town b on a Map is 14.6cm. If the scale is 1cm=14miles, what is the actual distance between towns

Answers

Answer:

204.4 miles

Step-by-step explanation:

Given data

we are told that on the map the distance is 14.6cm

scale

1cm=14miles

hence if

        1cm represents 14miles

then  14.6 cm will be x

cross multiply

x= 14.6*14

x=204.4 miles

Hence the distance is 204.4 miles
