The value of a if the lines 5x-ay+26=0 and 3x-y+2=0 intersect on the y-axis is; a = 13
How to solve the equation of a line?The general form of the equation of a line in slope intercept form is given as;
y = mx + c
where;
m is slope
c is y-intercept
We are given two equations of two lines as;
Line 1; 5x - ay + 26 = 0
Line 2; 3x - y + 2 = 0
Now, since they both intercept each other at the y-axis, it means that at the point of intersection, the value of x will be 0.
Thus, line 2 equation becomes;
3(0) - y + 2 = 0
y = 2
Putting 2 for y in line 1 equation gives;
5(0) - a(2) + 26 = 0
2a = 26
a = 26/2
a = 13

Answer:
[tex]\huge\purple {\boxed {m\angle FEG =23\degree}} [/tex]
[tex] \huge \orange {\boxed {m\angle FEH=113\degree}} [/tex]
Step-by-step explanation:
In the given circle, [tex] \overline{EG} [/tex] is diameter and [tex] \overline{EH} [/tex] is tangent at point E.
[tex]\therefore \widehat {EFG} [/tex] is a semicircular arc.
Since, measure of semicircular arc is 180°
[tex]\therefore m(\widehat {EFG})=180\degree... (1)[/tex]
[tex]\because m( \widehat {EF}) +m(\widehat {FG}) = m(\widehat {EFG}) [/tex] .... (2)
From equations (1) & (2)
[tex]\therefore 134\degree +m(\widehat {FG}) = 180\degree[/tex]
[tex]\therefore m(\widehat {FG}) = 180\degree-134\degree [/tex]
[tex]\therefore m(\widehat {FG}) = 46\degree [/tex]
By inscribed angle theorem:
[tex] m\angle FEG =\frac{1}{2} m(\widehat {FG} ) [/tex]
[tex] m\angle FEG =\frac{1}{2} \times 46\degree [/tex]
[tex]\huge\purple {\boxed {m\angle FEG =23\degree}} [/tex]
By tangent secant theorem:
[tex] m\angle FEH=\frac{1}{2} (46\degree +180\degree) [/tex]
[tex] m\angle FEH=\frac{1}{2} (226\degree) [/tex]
[tex] \huge \orange {\boxed {m\angle FEH=113\degree}} [/tex]
Use a net to find the surface area of the cone to the nearest
square centimeter. Use 3.14 for it.
23 cm
(The figure is not drawn to scale.)
The surface area of the cone is about cm2.
(Round to the nearest whole number as needed.)
Answer:
[tex]V=497.16\ cm^3[/tex]
Step-by-step explanation:
The attached figure shows a cone of radius 5 cm and height 19 cm. The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Substitute all the values,
[tex]V=\dfrac{1}{3}\times 3.14\times 5^2\times 19\\\\V=497.16\ cm^3[/tex]
So, the volume of the cone is equal to [tex]497.16\ cm^3[/tex].

4) If there was a coupon for 40% off, what is the final deconstructed
percent written as a DECIMAL? *. A.1.4
B.0.6
C.0.4
D.60%
Answer:
c
Step-by-step explanation:
Think of it like this. When you convert a percent to a decimal, just put a decimal point before the number. For example, 40%. You would put . before 40, making it 0.40, and you don't need the zero, so it becomes 0.4. For something like 8%, you would first put a zero before the 8, and then put a period before the zero, like so: 8%= 08%=0.08

If you deposited $10,000 in to a bank savings account on your 18th birthday....Said account yielded 3% compounded a nnually, how much money would be in your account on your 58th birthday?
Answer:
$32600
Step-by-step explanation:
Given data
Principal= $10000
Rate= 3%
Time= 58-18= 40 years
The compound interest expression is
A=P(1+r)^t
Substitute
A=10000(1+0.03)^40
A=10000(1.03)^40
A=10000*3.26
A=$32600
Hence the amount at the 58th birthda is $32600

Esh deposits $3500 in an account that
earns 3.75% interest each year. After the
first year, Esh has $3631.25 in the account.
After the second year, Esh has $3767.42 in
the account, and after the third year Esh has
$3908.70 in the account.
Answer:
Compound interest
Step-by-step explanation:
The question requires us to determine if the interest earned is a simple or compound interest
Simple interest = amount deposited x time x interest rate
Future value with compounding = A( 1 + r)^n
A = amount deposited
r = interest rate
n = time
We would calculate the simple interest and the future value in year 2
Simple interest in year 2 = $3500 x 0.0375 x 2 = 262.50
Future value in 2 years with a simple interest = 262.50 + 3500 = $3762.50
Future value in year 2 with compounding = 3500 x (1.0375)^2 = $3767.42
The value provided in year 2 with compounding matches that provided in the question. Thus, it is compounding of interest that is done

Simon bought a 10-pound bag of cat food. He gives his cat 0.3 pound of food per day. Which equation with two variables to describe how the amount of cat food in the bag changes over time.
Answer:
y = 10 - 0.3t
Step-by-step explanation:
Amount of cat food purchased= 10 pounds
Daily pounds fed to dog = 0.3 pounds
How the amount of cat food in bag changes over time ;
Let y = amount of cat food left in bag
t = number of days since cat food was purchased
Amount of cat food left in bag = amount of cat food purchased - (daily pounds fed to dog * Number of days since cat food was purchased)
y = 10 - 0.3t

will be graded
Use the evidence you gathered to tell the story of a hypothetical indigenous
community in the Americas and its experience involving the Columbian Exchange.
Come up with a community whose circumstances are typical of many in Central
America, the West Indies, or another part of the Americas that had direct contact with
Europeans. Tell the story in chronological order, but feel free to skip whole years or
decades so that you can cover each of the important topics related to the activity: the
availability of goods, the effects of disease, and the impact of European culture
(language and religion, for example), at the very least.
