5x^2-5x-5

the constant term in the simplified expression is -5.

Diego answer is correct.

The other form of triangle can be Right angled triangle.

A right-angled triangle is a triangle in which one of the angles is 90 degrees. The sum of the other two angles is 90 degrees. The sides that include the right angle are perpendicular and form the triangle's base. The third side is known as the hypotenuse, and it is the longest of the three sides.

Diego made the triangle with base angles 45 degree each and base length of 8 cm.

Yes. I agree with Diego answer.

but this is not the only triangle can be made.

As, two of the angle is 45 degree then the third angle must be 90 degree which is a right angle with Hypotenuse 8 cm.

Answer:

We accept H₀ we don´t have enough evidence to support that the proportion of certain town differs from that of National Information

Step-by-step explanation:

National Information:

p = 10,3 %      p = 0,103

Sample

Sample size    n₁  = 100

x₁  = 8

p₁  = x₁/100         p₁  = 8 / 100     p₁ = 0,08 %  

q₁  =  1 - p₁       q₁  = 1  - 0,08      q₁  = 0,92

Confidence Interval  CI = 95 %   significance level  α  = 5 %   α = 0,05

z(c) for α = 0,05  from z-table is  : 1,64

Test Hypothesis:

Null Hypothesis                                       H₀       p₁  = p

Alternative Hypothesis                           Hₐ       p₁ <  p

The alternative hypothesis suggest a one tail test to the left

z(s)  =  (  p₁  - p ) √p₁*q₁ / n₁

z(s)  = ( 0,08 - 0,103 )/√ 0,08*0,92/100

z(s)  =  - 0,023 / 0,027

z(s)  = - 0,85

Comparing  z(s)   and  z(c)

z(s) > z(c)     - 0,85  > -1,64

z(s) is in the acceptance region, we accept H₀

Answer: B

Step-by-step explanation:

It is B Beacuse you cant say its A beacsuse that wrong to the question you asked.

Answer:

B g(x)= 1/3x^2

Step-by-step explanation:

In this question, we have that:

[tex]f(x) = x^2[/tex]

So, when [tex]x = 3, f(x) = f(3) = 3^2 = 9[/tex]

What is g(x)?

We have that [tex]g(x) = 3[/tex], when [tex]x = 3[/tex]

[tex]\frac{3}{9} = \frac{1}{3}[/tex]

This means that g is a third of f, and the correct answer is given by option B.

It is not d because the paranthesis is elevated, which means that (1/3)^2 = 1/9,

Answer:

[tex]C' = (2,8)[/tex]

[tex]A' = (4,4)[/tex]

[tex]T' = (10,10)[/tex]

Step-by-step explanation:

Given

[tex]k =2[/tex]

[tex]C =(1,4)[/tex]

[tex]A = (2,2)[/tex]

[tex]T =(5,5)[/tex]

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

[tex]New = Old * k[/tex]

So:

[tex]C' = (1,4) * 2 = (2,8)[/tex]

[tex]A' = (2,2) * 2 = (4,4)[/tex]

[tex]T' = (5,5) * 2 = (10,10)[/tex]
