Answer:

her degree of accuracy in measurement is 0.05 cm (Option D)

Step-by-step explanation:

The degree of accuracy in the measurement of the botanist depends on the instrument used.

For a length of 3.56 centimeters, it shows that the length of the tomato seedling was measured using meter rule or tape.

Meter rule is graduated in 1 mm or 0.1 cm. The estimated uncertainty in measurement using meter rule is half of its graduation i.e ( ¹/₂ of 0.1 cm = 0.05 cm).

If the botanist measured the length of tomato seedling as 3.56 centimeters, then her degree of accuracy in measurement is 3.56 cm ± 0.05 cm.

Therefore, her degree of accuracy in measurement is 0.05 cm (Option D)

Harry is one third as old as his father. If his father is x 12 years old, how old is Harry? StartFraction x over 3 EndFraction 4
Mama L [17]

The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

\sqrt{3}x+4

<h3>How to write algebraic expression? </h3>

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Harry is one third as old as his father and his father is x+12 years old.To find the age of Harry, we need to convert the given statement into the algebraic expression.

Suppose the age of the Harry is <em>a</em> years and the age of his father is<em> b</em> years. Now Harry is one third as old as his father, thus

a=\dfrac{1}{3}b

Let the above equation is equation one.

As the father of Harry is x+12 years old. Thus put the value of age of his father in the equation one as,

a=\dfrac{1}{3}(x+12)\\a=\sqrt{3}x+4

The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

\sqrt{3}x+4\sqrt{3}x+4

Which statement regarding the function y=cos(x) is true?
MAVERICK [17]
<span>A. cos(x) = cos(-x)  [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph.  [false]
C. cos(x) = -cos(x)   [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin.   [false]</span>

Does -2(z+3)-z=-z-4(z+2) have one,zero or infinite solutions
Andrew [12]

Hello from MrBillDoesMath!

Answer:

One solution (z = -1)

Discussion:

-2(z+3)-z=-z-4(z+2)        =>

-2z -6 -z = -z -4z - 8       =>

-3z -6 = -5z -8                =>  add 6 to both sides

-2z = -5z -2                     => add 5z to both sides

3z = -5z +5z -3               =>

3z = -3                            =>

z = -1

Thank you,

MrB

How to graph y=-3x+15
steposvetlana [31]

Answer:

Well first you put the y-intercept on the graph. In this case it would be 15

So graph the point (0,15)

The you do the slope which is 3

so you always do rise over run for slope.

If 3 were a fraction it would be 3/1 so go up 3 points and the go right 1 point from (0,15)

hope this helps .-.
