Answers

Answer 1

Answer:

C is the answer. Can I get a brainliest

Answer 2

Answer:

A

Step-by-step explanation:

1* 2 + 2*0 + 0*(-3) = 2 + 0 + 0 = 2, so is not the option D

2*2 + (-1)*0 + (-1)*(-3) = 4+0+3 = 7, so is option A

will still calculate the last one just to make sure and we should get 6

0*2 + 3*0 + (-2)(-3) = 0+0+6 = 6

Answers

Answer:

11.7

Step-by-step explanation:

Step 1: Our output value 39.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 39 = 100%.

Step 4: Similarly, x = 30%.

Step 5: This results in a pair of simple equations:

39 = 100%(1)

x = 30%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

39/x = 100%/30%

Step 7: Again, the reciprocal of both sides gives

x/39 = 30/100

------> x = 11.7

Therefore, 30% of 39 is 11.7

The diagram shows a trapezium PQRS.



Calculate the area of the trapezium PQRS.

Answers

Area of trapeziaum 1/2*(6+8)*5=35

Answer:

AREA = 35cm

Formula in finding the trapezoid's area:

USE THIS FORMULA!: 1/2 × altitude × (base [tex]_{1}[/tex] + base [tex]_{2}[/tex])

(note: altitude is also known as the height)

Area = 1/2 × 5 × (6 + 8)

A = 1/2 × 5 × 14

Question:

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.

Solution:The perimeter of an equilateral triangle is 9n - 12.We know, perimeter of a triangle is the sum of the three sides of the triangle.Also, in an equilateral triangle, all the sides are equal.Therefore, the length of each side of the triangle

[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]

Answer:

The length of each side of the triangle is 3n-4.

The reflexive property of congruence states that any geometric shape is congruent to itself.

Answer:

C) Symmetric Property

Step-by-step explanation:

The Symmetric Property states that  If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.

Khan Academy also states that:

When a relation  has a symmetric property, it means that the if relation is true between two things, it is true in either order.  If VW ≅ XY, then XY ≅ VW.

Therefore, the correct answer is C) Symmetric Property.

do logarithmic functions have horizontal asymptotes?

Answers

9514 1404 393

Answer:

  not generally

Step-by-step explanation:

The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.

__

A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...

  f(x) = 1/log(x)

has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)

Perpendicular with a slope of 1/4 and

Perpendicular with a slope of 1/4

Neither, slopes are 1/4 and 5/6

O

Neither, slopes are 3/10 and 1/2

Answers

Answer:

Neither, slopes are 1/4 and 5/6

Step-by-step explanation:

Let's find the slope for Line 1: (-3,-1) and (-7,-2)

m1 = (-2+1)/ (-7+3)

= -1/-4

=1/4

Line 2: (2.-1) and (8,4)

m2= (-4+1)/ (8-2)

= -3/6

= - 1/2

These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is

Neither, slopes are 1/4 and 5/6
