Rate=\frac{\Delta temp}{\Delta time}
Rate=\frac{temp_{2}-temp_{1}}{time_{2}-time_{1}}
Rate=\frac{11.7\°-0\°}{6hr-0hr}
Rate=\frac{11.7\°}{6hr}
Rate=1.95\frac{\°}{hr}

The equation a = 50m + 100 represents the amount of money in Malorie’s bank account as a function of time, in months. The table
Gnesinka [82]

Answer:

A: 300 B: Malorie

Step-by-step explanation: Katina's account starts at $200 and increases by $20 each month. Malorie starts at only $100 but increases at a rate of $50 per month. for "A", Katina is 4 months in which equals $280. so, you take Malorie's $50 rate times the 4 months and you get $200. You then add that $200 to the starting $100 to equal $300.

B: 50m>20m. Malorie's monthly rate is listed in the equation as $50. Katina's rate of $20 comes from the $20 increase in her account each month.

Need help solving for x
yawa3891 [41]

Answer:

9.2

Step-by-step explanation:

The given triangle is a right angled triangle. To solve for any of the side length of such triangle, apply the trigonometry ratio formula which can easily be remembered as SOHCAHTOA.

SOH is Sin θ = opposite/hypothenuse,

CAH is Cos θ = Adjacent/hypotenuse

TOA is Tan θ = Opposite/adjacent

Thus, in the right triangle given, we have:

θ = 38°

Opposite side to the given angle = x

Hypotenuse = 15

We're going to use, sin θ = opposite/hypotenuse

Sin(38) = x/15

Multiply both sides by 15 to solve for x

15*sin(38) = x

15*0.616 = x

9.24 = x

<em>x ≈ 9.2 (to nearest tenth)</em>

F(x) ≥ -(x+4)^2<br>axis of symmetry: <br>vertex:
BlackZzzverrR [31]

Answer:

so the vertex is (-4, 0) and the axis of symmetry is x=-4

Step-by-step explanation:

f(x) ≥ -(x+4)^2

f(x) ≥ -(x- -4)^2

this is in the form

f(x)> a(x-h)^2 +k

where (h,k) is the vertex and h is the axis of symmetry

so the vertex is (-4, 0) and the axis of symmetry is x=-4

Input in standard form the equation of the given line.
mario62 [17]
Use equation of line which passes through the 2 points A(x_1,y_1),B(x_2,y_2).

y-y_1= \frac{y_2-y_1}{x_2-x_1}(x-x_1) \\ \\A(1,5),B(-2,3)&#10;\\ y-5= \frac{3-5}{-2-1}(x-1)&#10;\\y-5= \frac{2}{3} (x-1)&#10;\\y-5=\frac{2}{3}x-\frac{2}{3}&#10;\\3y-15=2x-2&#10;\\-2x+3y=-2+15&#10;\\-2x+3y=13

What is the solution for the system of equations?<br><br> -4x+y=-2<br> y+5=-6x
Aliun [14]

Answer:

(-3/10,-16/5)

Step-by-step explanation:

One way to solve a system of equations is by elimination.  We can take one equation and subtract the other equation from it to cancel out on of the variables making the equation into something we can solve.  In this case the Y's will cancel out because we have 1 Y in each equation

-4x+y=-2

6x+y=-5 subtract

-4x-6x=-10x

y-y=0

-2-(-5)=3

so our equation is -10x=3 and we can solve for x giving us x=-3/10

now we can plug -3/10 in for x into either of the original equations and solve for Y

y+5=-6(-3/10)

y+5=9/5

y=-16/5

so our answer is (-3/10,-16/5)

I hope this helps and please don't hesitate to ask if there is anything still unclear!
