To find the volume of an assumed rectangular-prism-shaped loaf of bread, use $V=l\times w\times h$ , where $V$ is the volume, $l$ is the length, $w$ is the width, and $h$ is the height.

there aren't any specific measurements given in the image but i would multiply the length of the bread with its width and then mulitply that with the bread's height.

V= l*w*h

Which type of function best models the data shown on the scatterplot?

Due to the u-shaped graph suggested by these data points, this would best be matched with a quadratic function.

Evaluate the function for the given value. If f(x) = -3x2 – 8, then f(-4)= ?

Ganezh [65]

Answer:

The answer is

Step-by-step explanation:

$f(x) = - 3 {x}^{2} - 8 \\$

To find f(-4) , substitute the value of x that's - 4 into f(x). That is for every x in f(x) , replace it with - 4

We have

$f( - 4) = - 3 ({ - 4})^{2} - 8 \\ = - 3(16) - 8 \\ = - 48 - 8 \: \: \: \: \:$

We have the final answer as

$f( - 4) = - 56$

Hope this helps you

Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, proj,u

11Alexandr11 [23.1K]

Answer:

Take $b = \frac{-17}{25}(7,1)$ as the projection of u onto v and $w \frac{1}{25}(-31,217)$ as the vector such that b+w =u

Step-by-step explanation:

The formula of projection of a vector u onto a vector v is given by

$\frac{u\cdot v}{v\cdot v}v$ , where $cdot$ is the dot product between vectors.

First, let b ve the projection of u onto v. Then

$b = \frac{u\cdot v}{v\cdot v}v= \frac{-6\cdot 7+8\cdot 1}{7\cdot 7+1\cdot 1}(7,1) = \frac{-34}{50}(7,1) = \frac{-17}{25}(7,1)$

We want a vector w, that is orthogonal to b and that b+w = u. From this equation we have that w = u-b = (-6,8)-\frac{-17}{25}(7,1)= \frac{1}{25}(-31,217)[/tex]

By construction, we have that w+b=u. We need to check that they are orthogonal. To do so, the dot product between w and b must be zero. Recall that if we have vectors a,b that are orthogonal then for every non-zero escalar r,k the vector ra and kb are also orthogonal. Then, we can check if w and b are orthogonal by checking if the vectors (7,1) and (-31, 217) are orthogonal.

We have that $(7,1)\cdot(-31,217) = 7\cdot -31 + 217 \cdot 1 = -217+217 =0$ . Then this vectors are orthogonal, and thus, w and b are orthogonal.
