Answer:

a) -2 degrees celsius

b) -5<-2

C) There would be an open dot on -2 and the line would go till the right end of the graph.

Step-by-step explanation:

a)-2 is warmer because -2 is a higher number than -5

b) -5 is less than -2

c) Every number above -2 on the graph is warmer than -2 so the line continues from -2 to then end.

Hope this helped:) maybe I could get brainliest?

Step-by-step explanation:

The area for a trapezoid is

$A=\frac{1}{2}h(b_{1}+b_{2})$

h is the length of ST, one of the bases is the length of MK, and the other base is the length of AS. First we'll find h:

The coordinates for S are (0, -2) and T are (1, 2). Using the distance formula:

$d=\sqrt{(1-0)^2+(2-(-2))^2$ and

$d=\sqrt{17}$ . So h = √17

Now for the length of MK. The coordinates for M are (-7, 4) and for K (5, 1). Using the distance formula again:

$d=\sqrt{(-7-5)^2+(4-1)^2}$ and

$d=\sqrt{(-12)^2+(3)^2}$ so

$d=\sqrt{153}$ which simplifies to

$d=3\sqrt{17}$ . So MK = 3√17.

Now for the length of AS. The coordinates for A: (-4, -1) and for S: (0, -2). Using the distance formula one more time:

$d=\sqrt{(-4-0)^2+(-1-(-2))^2}$ and

$d=\sqrt{(-4)^2+(1)^2}$ and

$d=\sqrt{17}$ . So AS = √17.

Now we can fill in our area formula:

$A=\frac{1}{2}(\sqrt{17})(3\sqrt{17}+\sqrt{17})$

Simplifying a bit:

$A=\frac{1}{2}(\sqrt{17})(4\sqrt{17})$ and simplifying a bit more:

$A=\frac{4*17}{2}$ and

A = 34

A recipe requires 3 cups of milk for every 4 cups of flour. Write a linear equation that describes the relationship.

Dmitry_Shevchenko [17]

Answer: $y=\dfrac{3}{4}x$

Step-by-step explanation:

Given

3 cups of milk are required for 4 cups of flour

Suppose there are x cups of milk and y cups of flour

So, according to the question

$\Rightarrow 3x=4y\\\\\Rightarrow y=\dfrac{3}{4}x$

The above equation represents the linear equation.

Use a(t) = −9.8 meters per second per second as the acceleration due to gravity. (Neglect air resistance.) A canyon is 2100 mete

Umnica [9.8K]

Answer:

$t \approx 20.7\,s$

Step-by-step explanation:

Given that rock experiments a constant acceleration, position function can be obtained by integrating twice:

$v(t) = v_{o} - a\cdot t$

$s(t) = s_{o} + v_{o}\cdot t -\frac{a}{2}\cdot t^{2}$

The initial conditions of the rock are, respectively:

$s_{o} = 2100\,m$

$v_{o} = 0\,\frac{m}{s}$

Position of the rock as a function of time is:

$s(t) = 2100\,m -(4.9\,\frac{m}{s^{2}})\cdot t^{2}$

The time taken for the rock to hit the canyon floor is:

$0\,m = 2100\,m - (4.9\,\frac{m}{s^{2}} )\cdot t^{2}$

$2100\,m = (4.9\,\frac{m}{s^{2}} )\cdot t^{2}$

$t = \sqrt{\frac{2100\,m}{4.9\,\frac{m}{s^{2}} } }$

$t \approx 20.7\,s$
