Okay you can set them equal to each other...

5.) y = x^2-7x+4; y = x-3
x-3 = x^2-7x+4
x^2-8x+4 = 0
(x-1) (x-7)
x = 1, 7

6.) y = x^2-5x+10; y = 2x^2-6x+4
x^2-5x+10 = 2x^2-6x+4
x^2-x-6 = 0
(x-3)(x+2)
x = 3, -2

Leslie invest 42,000 into an account that pays 7%compounded weekly. How much is the account worth after 5 years?

Answers

Answer:

$41,998.58

Step-by-step explanation:

The computation of the account worth after 5 years is shown below:

As we know that

Future value = Present value ×(1+ rate of interest)^number of years

= 42,000 × (1 + 0.07 ÷ 52)^5× 52

find the length . IF necessary round to the tenth

Answers

Answer:

24

Step-by-step explanation:

Finding the lengths of a Triangle is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

Your triangle is [tex]7^{2}[/tex] + [tex]b^{2}[/tex] = [tex]25^{2}[/tex]

Which is 49 + b = 625

Subtract the difference 625 - 49. then you get the following

A collection of coins contains a total of sixteen dimes and quarters. It is worth $2.20 in all. How many dimes are in the collection?

Answers

9514 1404 393

Answer:

  12 dimes

Step-by-step explanation:

Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...

  0.25q +0.10(16 -q) = 2.20

  0.15q +1.60 = 2.20 . . . . . . . simplify

  0.15q = 0.60 . . . . . . . . subtract 1.60

  q = 4 . . . . . . . . . . . divide by 0.15

  16-q = 12

There are 12 dimes in the collection.

In ATUV, the measure of _V=90°, the measure of ZT=66°, and TU = 93 feet. Find
the length of VT to the nearest tenth of a foot.
U
93
660
T
V
X

Answers

Answer:

VT = 37.8 ft

Step-by-step explanation:

Here, we want to get the measure of VT

We need the diagram of the triangle here

We can get this in the attachment

From the diagram, we have it that the hypotenuse is the length UT since it faces the right angle

VT does not face the given angle , nor the right angle; this mean VT is the adjacent

Mathematically, the trigonometric ratio that connects the adjacent to the hypotenuse is the cosine

Thus;

cos 66 = VT/UT

cos 66 = VT/93

VT = 93 * cos 66

VT = 37.83

To the nearest tenth of a foot, VT = 37.8 ft
