option D

Step-by-step explanation:

the correct answer is option D

A precise measurement is one in which we can measure the smallest of the value.

In 17.775 we can measure the smallest value of 0.001

In 18.55 we can measure smallest value  up to 0.01

In 17.5 we can measure smallest value  up to 0.1

In 18  we can measure smallest value of 1.

hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.

LaTasha was presented with the following data set and argued that there was no correlation between x and y. Is LaTasha correct?
andrezito [222]

Answer:

LaTasha is correct. There is no correlation between x and y. The slope of the line of best fit is zero, which shows that there is no negative or positive correlation.

I need to know the answer and how to solve this
AURORKA [14]

Answer:

135

Step-by-step explanation:

subtract 180 by 45 since a line is 180, that is what you get for the angle that is adjacent to angle 2, there is a rule if it is adjacent, they equal each other. thus, angle 2 is 135

I dont really know how to do soh cah toah. please help me find x.
Ipatiy [6.2K]
First notice that the triangle with sides x,y,a and the triangle with sides z,a+b,x are similar. This is true because the angle between sides x,y in the smaller triangle is clearly 30^\circ, while the angle between sides y,z in the larger triangle is clearly 60^\circ. So the triangles are similar with sides x,y,a corresponding to a+b,z,x, respectively.

Now both triangles are 30^\circ-60^\circ-90^\circ, which means there's a convenient ratio between its sides. If the length of the shortest leg is \ell_1, then the length of the longer leg is \ell_2=\sqrt3\ell_1 and the hypotenuse has length \ell_3=\sqrt{{\ell_1}^2+{\ell_2}^2}=2\ell_1.

Since x is the shortest leg in the larger triangle, it follows that a+b=2x, so a+b=15=2x\implies x=\dfrac{15}2

Suppose a baseball is thrown vertically upward from the ground with an initial velocity of Subscript[v, 0] ft/s. Its height abov
Zina [86]

Answer:

90.5

Step-by-step explanation:

Velocity is a time-derivative of displacement or the height, in this case.

s(t)=-16t^2+v_0t

v(t) = -32t+v_0

At maximum height, the velocity is 0 and the height is 128.

Substitute these values into both equations above,

0 = -32t+v_0

t=\dfrac{v_0}{32}

From the first equation,

128 = -16t^2 + v_0t

Substitute for t.

128 = -16(\dfrac{v_0}{32})^2 + v_0\times\dfrac{v_0}{32}

128 = -v_0^2/64 + v_0^2/32

128=\dfrac{v_0^2}{64}

v_0^2=8192

v_0=64\sqrt{2}=90.5
