Step-by-step explanation:

43. A "Square" cornfield, which means all 4 sides has the same lenght BxH

164.000 ft^2=404.96 NO

156.816 ft^2=396 Yes

174724 ft^2=418 Yes

215908 ft^2=464.66 NO

44. it's the same here, if the area is 81. then each side of the square is 9

1st figure: it has 12 sides x9 =108

2nd figure: it has 10 sides x9=90

3rd figure: has also 12 sides x9=108

45. 13^3= 13x13x13 = 2197

46. 25^2= 25x25 = 625

47. 15^3= 15x15x15 = 3375

48. 34^2= 34x34 = 1156

49. 5 root121= 5 (11)=55

50. -6.root36= - 6 (6)= -36

51. 10 root3 (8) = 10(2) = 20

52. -4. root 144= -4(12) = -48

Select the solution(s) of log2x=1−log(x+4).

mart [117]

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

Joshua used two wood beams, PC and QA, to support the roof of a model house.

Mazyrski [523]

Answer:

$\boxed{\boxed{PQ=3.6\ in}}$

Step-by-step explanation:

As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.

So,

$\dfrac{RC}{PR}=\dfrac{AC}{PQ}$

It is given as,

RC = 3.3

PR = 1.8

AC = 6.6

PQ = ??

Putting the values,

$\Rightarrow \dfrac{3.3}{1.8}=\dfrac{6.6}{PQ}$

$\Rightarrow PQ=\dfrac{6.6\times 1.8}{3.3}=3.6$

Write an equation of the parabola that has the same shape as the graph of f(x), but with the point (,) as the vertex.

erik [133]

Answer:

y=3(x-9)^2+4

Step-by-step explanation:

To move a parabola horizontally to the right, subtract 9.

To move it upward 4 units, you simply have to add 4.

These do not change the characteristics of the shape. I suggest looking at a set of rules that affect how the parabola moves horizontally and vertically.
