Answer:

40cm

Step-by-step explanation:

1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².

2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15

3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.

A train ticket in a certain city is $2.00. People who use the train also have the option of purchasing a frequent rider pass for

DENIUS [597]

Answer:

the number of times in a month the train must be used, so that the total monthly cost without the pass is the same as the total monthly cost with the pass, is b. 24 times

Step-by-step explanation:

in normal purchase, train ticket (A) = $2.00

using frequent pass,

frequent pass (P) = $18

train ticket using frequent pass (B) = $1.25

Now, let assume the number of times in a month the train must be used = M

so,

A x M = P + (B x M)

$2.00 x M = $18 + ($1.25 x M)

($2.00 x M) - ($1.25 x M) = $18

M x ($2.00 - $1.25) = $18

M = $18 : $0.75

M = 24

Thus, the number of times in a month the train must be used is 24 times

The vertex of this parabola is at (-5, -2). When the x-value is -4, the y-value is 2. What is the coefficient of the squared exp

Montano1993 [528]

Answer:

The coefficient of the squared expression in the parabola equation is $a=4$

Step-by-step explanation:

The equation of a parabola in its vertex form is:

$y = a(x-h) ^ 2 + k$

Where the vertex of the parabola is the point (h, k)

a is the ceoficiente of the term to the square.

We need to find the equation of a parabola that has its vertex in the point:

(-5, -2)

So:

$h = -5\\\\k = -2$

Therefore the equation is:

$y = a(x - (-5)) ^ 2 -2\\\\y = a(x + 5) ^ 2 -2$

We know that the point (-4, 2) belongs to this parable. Then we can find the value of a by replacing the point in the equation of the parabola

$(2) = a((-4) + 5) ^ 2 -2\\\\2 = a(1) ^ 2 -2\\\\2 = a -2\\\\a = 4$

Finally the coefficient is a = 4

xz_007 [3.2K]

Answer:

397.7 m²

Step-by-step Explanation:

Step 1: find m < W

W = 180 - (33+113) (sum of ∆)

W = 34°

Step 2: find side UV using the law of sines

$\frac{UV}{sin(W)} = \frac{VW}{sin(U)}$

$\frac{UV}{sin(34)} = \frac{29}{sin(33)}$

Multiply both sides by sin(34)

$\frac{UV}{sin(34)}*sin(34) = \frac{29}{sin(33)}*sin(34)$

$UV = \frac{29*sin(34)}{sin(33)}$

$UV = 29.8 m$ (approximated)

Step 3: find the area using the formula, ½*UV*VW*sin(V)

area = ½*29.8*29*sin(113)

Area = 397.7 m² (rounded to the nearest tenth.
