Step-by-step explanation:

Given

Mr. Claussen needs 15 Pounds of ground beef

It is stated that 2 pounds of beef cost $4.40

Using unitary method

1 Pound cost $\frac{4.4}{2}=\$2.2$

An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river 20 meters wide. The hei

Title:

<h2>Check the explanation.</h2>

Step-by-step explanation:

The standard form of an ellipse is $\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } = 1$ .

The span of the river is 20 meters. As per the given condition, y-axis will pass through the middle point of the river. That is why, the value of a will be $\frac{20}{2} = 10$ .

Since the height of the arc is 6, the value of b is 6.

The equation of the arc will become $\frac{x^2}{{10}^2} + \frac{y^2}{6^2} = 1$ .

What is a11. A12. A21. A22

Ierofanga [76]

Answer:

$a_{11} =-1\\a_{12} =3\\a_{21} =5\\a_{22} =3/2\\$

Step-by-step explanation:

$2X-\left[\begin{array}{ccc}-4&8\\2&-2\end{array}\right] =\left[\begin{array}{ccc}2&-2\\8&5\end{array}\right]\\X=\frac{1}{2} (\left[\begin{array}{ccc}-4&8\\2&-2\end{array}\right] +\left[\begin{array}{ccc}2&-2\\8&5\end{array}\right])\\X=\frac{1}{2} (\left[\begin{array}{ccc}-4+2&8-2\\2+8&-2+5\end{array}\right] )\\X=\frac{1}{2} (\left[\begin{array}{ccc}-2&6\\10&3\end{array}\right] )\\X= (\left[\begin{array}{ccc}\frac{1}{2}(-2)&\frac{1}{2}(6)\\\frac{1}{2}(10)&\frac{1}{2}(3)\end{array}\right] )\\$

$X= (\left[\begin{array}{ccc}-1&3\\5&3/2\end{array}\right] )$

$a_{11} =-1\\a_{12} =3\\a_{21} =5\\a_{22} =3/2\\$

Answer is 9

A(x)=f(b)-f(a)/b-a

where a=-10 b=10
f(x)= x^2+9x+18

f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9
