A block is cut into equal units.

Mathematics
1 answer:
kvasek [131]4 years ago

Answer:

140 g

Step-by-step explanation:

Note that

  • 10=\underline{2}\cdot \mathbf{5};
  • 20=\underline{2}\cdot 2\cdot \mathbf{5};
  • 35=\mathbf{5}\cdot 7

As you can see 5 is the common factor for all three numbers and 2 is the common factor only for the first two numbers. So, the greatest common factor

GCF(10,20,35)=5\cdot 2\cdot 2\cdot 7=140\ g.

The smallest mass of the block should be 140 g (it can be cut into 14 pieces of 10 g weight, 7 pieces of 20 g weight or 4 pieces of 35 g weight).

The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative
sertanlavr [38]

The true statement about the function f(x) = -x² - 4x + 5 is that:

  • The range of the function is all real numbers less than or equal to 9.
<h3 /><h3>What is the domain and range for the function of y = f(x)?</h3>

The domain of a function is the set of given values of input for which the function is valid and true.

The range is the dependent variable of a given set of values for which the function is defined.

  • The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞

For a parabola ax² + bx + c  with the vertex \mathbf{(x_v,y_v)}

  • If a < 0, then the range is f(x) ≤ \mathbf{y_v}
  • If a > 0, then the range f(x) ≥  \mathbf{y_v}
  • Here; a = -1,

The vertex for an up-down facing parabola for a function y = ax² + bx + c is:

\mathbf{x_v = -\dfrac{b}{2a}}

Thus,

  • vertex \mathbf{(x_v,y_v)} = (-2, 9)

Range: f(x) ≤ 9

Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.

50 Pts!! Brainliest!! Answer ASAP, thx.
Y_Kistochka [10]

Answer:

1/625

Step-by-step explanation:

When you multiply, you add the exponents. You now have 6^{-4}. This is equivalent to \frac{1}{5^{4} } which equals 1/625.

Please solve these two questions :) - Use the graphs to solve the equations provided.
harkovskaia [24]

Answer:

7.(1,0) and (-4,0)

8.  (-3,0) and (-2,0)

Step-by-step explanation:

7.

When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are 1 and -4

(1,0) and (-4,0)

8.  When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are -3 and -2

(-3,0) and (-2,0)
