Hi! You have to put the protractor on the middle dot to figure it out. I can’t figure it out because of that. Good luck!

Sorry but I see that you can use the “interactive protractor” and see how many degrees the angle is. But all I can tell you is that it’s an acute angle

What units could you use to measure the height of a hexagonal prism?

LenaWriter [7]

The answer is centimeters (cm)

Height is 1D dimension so we cannot use cm^2 or cm^3 to measure some distance. With cm^2 we measure surface (because surface is 2D that is why it has this ^2 next to cm) and cm^3 is unit for measuring volume (volume is 3D it has height, width and thickness that is why it has ^3)
cm^4 cannot be the answer since there is no more than 3 dimensions.

Round 27346 to 2 significant figures i need a step by step expansion

belka [17]

Answer:

27000

Step-by-step explanation:

We want to round 27346 to 2 significant figures.

Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.

Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.

Whats the answer to 2y^0-(3y)^0

mrs_skeptik [129]

Answer:

Step-by-step explanation:

To answer this question, we need to that any number (except zero) raised to power 0 is equal to 1. With that in mind, let's solve this:

2y^0 - (3y)^0

= 2(1) - (1)

= 1

Note: 2y^0 = 2(y^0) = 2(1) = 2 whereas

(2y)^0 = 1

the standard for of the equation of a parabola is y=x^2+4x+11. What is the vertex for of the equation?

Eva8 [605]

Convert to vertex form

or easier
for y=ax²+bx+c
the x value of the vertex is $\frac{-b}{2a}$
and the y value is found by subsituting the x value in for x

so
y=1x²+4x+11
a=1
b=4

the x value of the vertex is $\frac{-4}{2(1)}=\frac{-4}{2}=-2$

the y value is found by subsituting -2 for x
y=(-2)²+4(-2)+11
y=4-8+11
y=7

the vertex is (-2,7)
