Answer:

20y^7. this is because the exponents are added together because the variable attached to the coefficient are the same therefor the coefficients are multiplied, and the exponents are added together.

Answer:

10y^7

Step-by-step explanation:

2y^4\times 5y^3

In order to multiply powers of the same base, add their exponents, add 4+3=7,

2y^7\times 5

Multiply 2 × 5=10

10y^7

Hope this helps! :)

¿por que en los mapas se respeta la misma escala? Ayudenme por favor esta es otra pregunta ¿qué pasaría si una parte del mapa se
7nadin3 [17]

Answer:

Ok, supón que conoces exactamente tu posición en un mapa, y también sabes a donde quieres ir.

Podes ver en ese mapa la distancia entre tu posición y el lugar al que quieres ir, ahora, si la escala del mapa es conocida (por ejemplo 1cm = 1km) y constante, entonces vos podes medir la cantidad de centímetros entre tu posición y tu destino, y multiplicar ese numero por la escala, de esta forma conociendo la distancia real entre tu posición y tu destino.

Ahora, si la escala no es constante, entonces es imposible saber exactamente la distancia entre nuestra posición y nuestro destino, entonces este mapa no sirve realmente para ubicarnos/guiarnos, entonces no funciona como un mapa.

En el caso de que una parte este en una escala y otra parte en otra, en la primera parte un centímetro en el mapa equivaldría a una distancia X en la realidad, y en la otra zona un centímetro en el mapa equivaldría a una distancia Y en la realidad.

Donde X es diferente de Y, ahora, cuando queremos calcular la distancia entre dos lugares tendríamos que saber exactamente en que lugar se da el cambio de escala (para saber si usamos X o Y). Lo que hace que leer este mapa sea bastante mas difícil que leer un mapa normal.

Which statement best describes the function h(t) = 210 – 15t? h is the function name; h(t) is the input, or independent variable
vazorg [7]
<span>The function h(t) = 210 – 15t has the slope-intercept form of the equation of a straight line.  The y-intercept represents the amount h at the very beginning (when t=0).  The negative slope (-15) represents the amount by  which h will decrease if t is increased by 1.

We are manipulating the value of time, t, so time, t, is the independent variable, and h(t) = y is the dependent variable.</span>

The data set below has an outlier.
nika2105 [10]
Data set: <span>2, 10, 10, 11, 11, 12, 12, 12, 13, 14, 14
</span>
range: 14 - 2 = 12
median: 12
lower quartile = 10
interquartile range = 4

Data set w/o outlier 2: <span>10, 10, 11, 11, 12, 12, 12, 13, 14, 14

range: 14 - 10 = 4
median: 12
lower quartile: 10.5
interquartile range = 3.5

The value that change the most by removing the outlier is A.) THE RANGE.</span>
