Answer:

x=38.5

Step-by-step explanation:

$\sqrt{23^{2}- 18^{2}} =\sqrt{205}$

cos(x)= $\frac{18^{2} +23^{2} -205}{2(18)(23)}$

x=38.5(correct to the nearest tenth)

Deja has two baskets of berries. One of the baskets has 3 3/8 pounds of berries and the other basket has 2 7/8 pounds of berries

ElenaW [278]

Answer:

(b) The number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

Step-by-step explanation:

The amount of berries in first basket = 3 3/8 pounds

Now, $3\frac{3}{8} = 3+\frac{3}{8} = 3 + 0.375 = 3.375$

So, the amount of berries in first basket = 3.375 pounds

The amount of berries in second basket = 2 7/8 pounds

Now, $2\frac{7}{8} = 2+\frac{7}{8} = 2 + 0.875 = 2.875$

So, the amount of berries in second basket = 2.875 pounds

Now, the total berries = Berries in ( First + Second) basket

= 3.375 pounds + 2.875 pounds

= 6.25 pounds

So, the number of pounds each person would have = $\frac{\textrm{Total weight of viable berries}}{\textrm{4}} = \frac{6.25}{4} = 1.5625$

Now, $1.5625 = 1 + 0.5625 = 1 + \frac{5625}{10000} = 1 + \frac{5}{8} = 1\frac{5}{8}$

So, the number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

Suppose a parabola has an axis of symmetry at x = -8 , a maximum height of 2, and passes through the point (-7, -1). Write the e

lidiya [134]

As it has a maximum value the coefficient of x^2 will be negative

The vertex will be at (-8,2) so in vertex form it is

y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:

-1 = a(-7+8)^2 + 2

-1 = a + 2 so a = -3

answer is y = -3(x + 8)^2 + 2

in standard form this is y = -3x^2 -48x - 190
