Answer:

  False

Step-by-step explanation:

This is an erroneous statement, so we presume it is supposed to be a true/false question. It is false.

__

Corresponding angles are only congruent in certain geometries. One such is where a transversal crosses parallel lines. There are a number of sets of corresponding angles in that geometry, and additional congruent angles that are not "corresponding."

Base angles in an isosceles triangle are equal, but not "corresponding." The presumption that equal angles are corresponding is FALSE.

Find the dot product of two vectors if their lengths are 4 and 1/2 and the angle between them is π/4.
Luba_88 [7]
The dot product is a technique that solves the resultant vector through the use of matrices. Since we have no coordinates, we can't use matrices. However, we can still solve the resultant vector (red line) through cosine law. The solution is as follows:

R² = 4² + (1/2)² - 2(4)(1/2)(cos π/4)
R = √13.42
R = 3.66

The resultant vector has a magnitude of 3.66.

Fraction of household owning pets = \frac{2}{5}

Fraction \; of \; household \; owning \; cats \; \\\\=\; \frac{1}{3} \; of\; Fraction \; of\; household\; owning \; pets \\\\=\frac{1}{3}  \times\frac{2}{5}  \\ \\Multiply \; numerator\; with\; numerator\; and\; denominator\; with\; denominator\\\\=   \frac{1 \times 2}{3 \times 5}= \frac{2}{15}

Conclusion:

The fraction of the household own cats is <em>two-fifteenth </em>

PLEASE HELP!! Please show your work in explanation no nonsense or blank answers please ;)
krok68 [10]

Answer:

r = 4.908

Step-by-step explanation:

V  = 885

height (given in the picture) = 11.7

V = \pi r^2h

V = (3.14)(r^2)(h)

885 = (3.14)(r^2)(11.7)

885/3.14/11.7 = r^2

Take the square root and you get 4.908.
