The line tilts up to the right, so the slope is positive.

The shading is below the line, so the inequality sign is <=.

Answer: C. y <= 4x + 2

4 0

First, look if y is greater or less than on the graph. Y is less than the line so the sign will be a less than symbol ≤.

Second, look at the slope. The slope is going up 4 and right 1 so the slope is 4.

Therefore, your answer is C. y ≤ 4x + 2

A cereal box is a rectangular prism that is 8 inches long and 2 1/2 inches wide. The volume of the box is 200in3. What is the he
Zarrin [17]

Answer:

Height=10\, inches

Step-by-step explanation:

Volume of a Rectangular Prism is :

             Length\times Width \times Height

For,

Volume=200\,inch^3\\\\Length= 8\,inches\\\\Width=2\dfrac{1}{2}=\dfrac{5}{2}\\\\  Height=?\\

200=8\times \dfrac{5}{2}\times Height\\\\ 200=4\times 5\times Height\\\\200=20\times Height\\\\Height=\dfrac{200}{20}\\\\ Height=10\,inches

The Height of the rectangular prism is: 10\,inches

the function below represents the number of zombies, N, where t is the number of years since the zombies gained control of earth
raketka [301]
There is missing information about this question that I found online.
Given function is:
N(t) = 300\cdot 2^{-\frac{t}{8}}
The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay. 
In general, we can write down exponential functions like this:
f(x)=b^{ax}
Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:
f(x)=b^{-ax}=\frac{1}{b^{ax}}
We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.

Indique la propuesta correcta con respecto a los instrumentos de medida: a) El Voltímetro A.C. Mide valor medio b) El Voltímetro
Gre4nikov [31]

Answer:

Las propuestas correctas son;

a) Voltímetro de CA Mide el valor medio

La magnitud del voltaje de corriente alterna varía periódicamente con el tiempo, dentro de un rango dado

El voltímetro de CA proporciona la lectura y, por lo tanto, mide el valor medio del voltaje, el voltaje pico o el R.M.S. valor de la tensión

b) El voltímetro de CC mide el valor máximo

Los valores de voltaje de un circuito de corriente de CC se fijan con el tiempo y, por lo tanto, el voltímetro de CC mide los voltajes máximos en el circuito.

c) El amperímetro de CA mide el valor medio

Similar a la medición de voltaje de CA, el amperímetro de CA mide el valor de corriente medio

d) El A.C. mide el valor efectivo

La raíz cuadrada media o R.M.S. valor es el valor medido por un R.M.S. Medidor de A.C.

e) El D.C. se conecta en paralelo

Todos los voltímetros se colocan en paralelo con el circuito desde el que se va a medir el voltaje.

Sin embargo, un amperímetro de CC está conectado en serie
