20.3

Step-by-step explanation:

Answer:

Step-by-step explanation:

u=6i-j

v=7i-4j

u.v=|6i-j||7i-4j| cos α,where α is the angle between u & v.

(6i-j).(7i-4j)=√(6²+(-1)²)√(7²+(-4)²) cos α

(6)(7)+(-1)(-4)=√37√65 cos α

42+4=√37√65 cos α

[tex]\cos \alpha =\frac{46}{\sqrt{37} \sqrt{65} } \\\alpha =\cos^{-1}\frac{46}{\sqrt{37} \sqrt{65} } \approx 20.28^\circ \approx 20.3^\circ[/tex]

For what value(s) of x is the expression undefined?
х/(x+2)(x-3)
a) 0, 2, 3
b) -2,3
c) 2, -3
d) -2,-3
Choose

Answers

Answer:

Answer b): -2, 3

Step-by-step explanation:

Recall this is a rational function with vertical asymptotes at the points where the denominator becomes zero. That is:

for x = -2 (that brings x+2 = 0) and for x = 3 (that brings x - 3 = 0)

Therefore, select answer b).

What are the coordinates of the point on the directed line segment from (-10, -3)
to (-3, -3) that partitions the segment into a ratio of 3 to 4?

Answers

9514 1404 393

Answer:

(-7, -3)

Step-by-step explanation:

The point is the weighted sum of the end point coordinates. The weights are the reverse of the adjacent segment proportions.

P = (4(-10, -3) +3(-3, -3))/7 = (-40-9, -12-9)/7 = (-49, -21)/7

P = (-7, -3)

The point that partitions the segment in the desired fashion is (-7, -3).

_____

Alternate solution

The given segment can be recognized as a horizontal segment of length 7. Then the desired point is 3 units from the first end, so at (-10+3, -3) = (-7, -3).

6. HANG GLIDING Aida
was hang gliding. After losing
35 feet in altitude, she was
gliding at 125 feet. Write and
solve an equation to find her
height when she started hang
gliding.

Answers

Answer:

35+125=160

She was 160 feet up when she began hang gliding

Answer:

160

Step-by-step explanation:

let A represent Aida hang gliding

we know that she was at 125 ft in the air

we know that she lost 35 ft in altitude

so the equation would be

125=A[-35]

what is boxed you change the opposite so the opposite of subtraction would be addition.

125=A[-35]

125=A+35

now we move the +35 under 125

if we add 125 and 35 it would give us 160 so the answer would be 160

What is the total interest earned in two years on an account containing $500 at 3.5% interest, compounded annually?

Answers

Answer: $35.6125

Step-by-step explanation:

3.5% = 0.035

Let's find the deposit amount with interest at the end of the first year:

500 + 500 · 0.035 = 517.5

Let's find the amount of the deposit with interest at the end of the second year:

517.5 + 517.5 · 0.035 = 535.6125

Find the total interest earned over two years:

535.6125 - 500 = 35.6125

Read the excerpt from Seaplanes by Roberto BarerraFlying boats have a fuselage, or body, that looks and acts like a ships hull. This hull enables them to float on the water very easily. Two small floats underneath its wings keep the flying boat stable in rough water. These seaplanes are usually larger and more stable on water than floatplanes are. A floatplane is a seaplane that has two long floats, called pontoons, under the fuselage. This is the only part of the plane that touches the water. Unlike flying boats, floatplanes often come in a wide variety of sizes. An amphibious vehicle can be either a flying boat or a floatplane with wheels. This allows the aircraft to land on both land and water.Which BEST describes the purpose of the paragraph?A.to explain how seaplanes are usedB.to encourage people to use seaplanesC.to list all of the types of seaplanesD.to describe the different parts of seaplanes what is the work done when a 400.n force is use to lift a 400.n object 3.5 meters strait up what is the molar mass of Br2 in grams Find the value of x.ABCD EFGH During operations outside declared hostilities, you may delay contact with local authorities.
